 This is  a summary of a book titled “We are eating the Earth: the race to fix our food system and save our climate” written by Michael Grunwald and published by Simon and Schuster in 2025.

In “We are eating the Earth: the race to fix our food system and save our climate,” Michael Grunwald embarks on a compelling journey through the tangled web of food production, land use, and climate change. The book opens with a stark warning: humanity stands at a crossroads, and the choices we make about how we produce and consume food will determine whether we avert or accelerate a climate disaster. For years, the global conversation about climate mitigation has centered on replacing fossil fuels with cleaner energy sources. Yet, as Grunwald reveals, this focus overlooks a critical truth—our current methods of land use and food production account for a full third of the climate burden. The story unfolds as a true-life drama, populated by scientists, policymakers, and activists, each wrestling with the complexities of science and politics, and each striving to find solutions before it’s too late.

Grunwald’s narrative draws readers into the heart of the problem: the way we produce food and use land must change. He explores the paradoxes and unintended consequences of well-intentioned climate policies. For example, the idea of using crops to replace fossil fuels—once hailed as a climate-friendly innovation—proves to be counterproductive. The production of ethanol from corn, which gained popularity in the 1970s and surged again in the early 2000s, was promoted as a way to reduce dependence on foreign oil and lower greenhouse gas emissions. However, as former Environmental Defense Fund attorney Tim Searchinger discovered, the reality is far more complex. Ethanol production not only fails to deliver the promised climate benefits, but also increases demand for farmland, leading to deforestation and the loss of natural carbon sinks. The research that supported biofuels often neglected the fact that natural vegetation absorbs more carbon than farmland, and the push for biofuels has threatened rainforests and contributed to food insecurity.

The book also examines the environmental harm caused by burning wood for fuel. Policies in the European Union and elsewhere encouraged the use of biomass, primarily wood, to generate electricity, under the mistaken belief that it was climate-friendly. In reality, burning wood releases carbon and diminishes the land’s future capacity to absorb it. The way carbon loss is accounted for—at the site of tree cutting rather than where the wood is burned—has led to flawed policies that exacerbate climate change rather than mitigate it. Even as the US Environmental Protection Agency initially rejected the climate benefits of biomass, political shifts reversed this stance, further complicating efforts to address the crisis.

Grunwald’s exploration of food production reveals a host of challenges. Meeting the world’s growing demand for food without increasing greenhouse gases or destroying forests is no easy task. Raising animals for meat and dairy requires far more cropland than growing plants, and animal products account for half of agriculture’s climate footprint. Searchinger’s message—“Produce, Reduce, Protect, and Restore”—serves as a guiding principle for climate-friendly strategies. These include making animal agriculture more efficient, improving crop productivity, enhancing soil health, reducing emissions, and curbing population growth. The book highlights the importance of reducing methane from rice cultivation, boosting beef yields while cutting consumption, restoring peat bogs, minimizing land use for bioenergy, cutting food waste, and developing plant-based meat substitutes.

The narrative delves into the promise and pitfalls of meat alternatives. While companies have invested heavily in alternative proteins, the path to scalable, affordable, and palatable meat replacements has been fraught with difficulty. The rise and fall of fake meat products follow the Gartner Hype Cycle, with initial excitement giving way to disappointment and skepticism about their environmental benefits. For many, meat replacements serve as a transitional product, but the future of the industry remains uncertain, as scaling up remains a significant hurdle.

Regenerative agriculture, once seen as a panacea, is scrutinized for its limitations. Practices such as reduced chemical use, less tilling, and managed grazing do help store carbon and provide social and economic benefits. However, Searchinger argues that regenerative agriculture alone cannot solve the climate crisis, as much of its benefit comes from taking land out of production, which can inadvertently increase pressure to convert more open land into farms.

Grunwald also explores technological innovations that could help increase crop yields and reduce the land needed for food production. Artificial fertilizers have boosted yields but are costly pollutants. New approaches, such as introducing nitrogen-fixing microbes, offer hope for more sustainable agriculture. Advances in animal agriculture, including high-tech farming techniques and gene editing, show promise for increasing efficiency and reducing emissions, though resistance to these innovations persists. Aquaculture, too, presents opportunities and challenges, as fish are more efficient than land animals but raising them in captivity introduces new problems.

Gene editing emerges as a beacon of hope, with scientists experimenting to enhance crop yields, combat pests, and improve food quality. The development of drought- and flood-resistant trees like pongamia, and the investment in biofuels and animal feed, illustrate the potential of biotechnology, even as skepticism and financial barriers remain.

Throughout the book, Grunwald emphasizes the difficulty of changing agriculture. Precision farming and other tech advances have made megafarms more productive and environmentally friendly, but these gains are not enough to meet global food demands, especially as climate change complicates implementation. Vertical farms and greenhouses offer solutions for some crops, but scaling these innovations is slow and challenging.

Grunwald’s narrative is one of cautious optimism. He points to Denmark as an example of how climate-friendly policies—taxing agricultural emissions, restoring natural lands, and encouraging less meat consumption—can make a difference. The ongoing struggle between food production and climate damage is complex, with trade-offs involving animal welfare, plastic use, and political opposition to climate action. Yet, Grunwald insists that even imperfect solutions can move us in the right direction. More funding for research, ramping up existing technologies, and linking subsidies to forest protection are among the measures that could help. In the end, innovation, grounded in reality and supported by sound policy, remains humanity’s best hope for saving both our food system and our climate.

 Across aerial drone analytics, the comparison between visionLLMs and classical CNN/YOLO detectors is beginning to look like a tradeoff between structured efficiency and semantic flexibility rather than a simple accuracy leaderboard battle. YOLOs evolution from v1 through v8 and into transformeraugmented variants has been driven by exactly the kinds of requirements that matter in urban aerial scenesrealtime detection, small object robustness, and deployment on constrained hardware. The comprehensive YOLO survey by Terven and CordovaEsparza systematically traces how each generation improved feature pyramids, anchor strategies, loss functions, and postprocessing to balance speed and accuracy, and emphasizes that YOLO remains the de facto standard for realtime object detection in robotics, autonomous vehicles, surveillance, and similar settings. Parking lots in oblique or nadir drone imagerydense, small, often partially occluded carsfit squarely into the hard but wellstructured regime these models were built for.

VisionLLMs enter this picture from a different direction. Rather than optimizing a single forward pass for bounding boxes, they integrate largescale imagetext pretraining and treat detection as one capability inside a broader multimodal reasoning space. The recent review and evaluation of visionlanguage models for object detection and segmentation by Feng et al. makes that explicit: they treat VLMs as foundational models and evaluate them across eight detection scenariosincluding crowded objects, domain adaptation, and small object settings—and eight segmentation scenarios. Their results show that VLMbased detectors have clear advantages in openvocabulary and crossdomain cases, where the ability to reason over arbitrary text labels and semantically rich prompts matters. However, when we push them into conventional closedset detection benchmarks, especially with strict localization requirements and dense scenes, specialized detectors like YOLO and other CNNbased architectures still tend to outperform them in raw mean Average Precision and efficiency. In other words, VLMs shine when we want to say “find all the areas that look like improvised parking near stadium entrances” even if we never trained on that exact label, but they remain less competitive if the task is simply “find every car at 0.5 IoU with millisecond latency.”

A qualitative comparison of vision and visionlanguage models in object detection underscores this pattern from a different angle. Rather than only reporting mAP values, Rakic and Dejanovic analyze how visiononly and visionlanguage detectors behave when confronted with ambiguous, cluttered, or semantically nuanced scenes. They note that VLMs are better at leveraging contextual cues and language priorsunderstanding that cars tend to align along marked lanes, or that certain textures and shapes cooccur in parking environments—but can suffer from inconsistent localization and higher computational overhead, especially when used in zeroshot or textprompted modes. CNN/YOLO detectors, by contrast, exhibit highly stable behavior under the same conditions once they are trained on the relevant aerial domain: their strengths are repeatability, tight bounding boxes, and predictable scaling with resolution and hardware. For an analytics benchmark that cares about usable detections in urban parking scenes, this suggests that YOLOstyle models will remain our baseline for hard numbers, while VLMs add a layer of semantic interpretability and openvocabulary querying on top.

The VLM review goes further by explicitly varying finetuning strategies—zeroprediction, visual finetuning, and textprompt tuningand evaluating how they affect performance across different detection scenarios. One of their core findings is that visual finetuning on domainspecific data significantly narrows the gap between VLMs and classical detectors for conventional tasks, while preserving much of the openvocabulary flexibility. In a drone parkinglot scenario, that means a VLM finetuned on aerial imagery with car and parkingslot annotations can approach YOLOlike performance for find all cars while still being able to answer richer queries like highlight illegally parked vehicles or find underutilized areas in this lot by combining detection with relational reasoning. But this comes at a cost: model size, inference time, and system complexity are higher than simply running a YOLO variant whose entire architecture has been optimized for singleshot detection.

For aerial drone analytics stacks like the ones we are exploring, the emerging consensus from these surveys is that visionLLMs and CNN/YOLO detectors occupy complementary niches. YOLO and related CNN architectures provide the backbone for highthroughput, highprecision object detection in structured scenes, with wellunderstood tradeoffs between mAP, speed, and parameter count. VisionLLMs, especially when lightly or moderately finetuned, act as semantic overlays: they enable openvocabulary detection, naturallanguage queries, and richer scene understanding at the cost of heavier computation and less predictable performance on dense, smallobject detection. The qualitative comparison work reinforces that VLMs are most compelling when the question isnt just is there a car here? but what does this pattern of cars, markings, and context mean in human terms?. In a benchmark for urban aerial analytics that includes tasks like parking occupancy estimation, illegal parking detection, or semantic tagging of parking lot usage, treating YOLOstyle detectors as the quantitative groundtruth engines and VLMs as higherlevel interpreters and judges would be directly aligned with what the current research landscape is telling us.

 Across aerial drone analytics, the comparison between vision‑LLMs and classical CNN/YOLO detectors is beginning to look like a trade‑off between structured efficiency and semantic flexibility rather than a simple accuracy leaderboard battle.

 In the aerial drone analytics space, the comparison between plain visionLLMs, ReActstyle agents, and broader agentic frameworks is about how we want our system to behave under pressure: do we want a single powerful model that “understands” scenes, or an ensemble of agents that can plan, probe, and correct themselves over time. The recent UAVCodeAgents work is a clean illustration of the second camp. It builds a multiagent framework on top of large language and visionlanguage models, using the ReAct (Reason + Act) paradigm to interpret satellite imagery, ground highlevel natural language instructions, and collaboratively generate UAV trajectories. A visiongrounded pixelpointing mechanism lets agents refer to precise locations on aerial maps, while a reactive thinking loop supports iterative reflection and dynamic goal revision in evolving environments. Evaluated on largescale fire detection missions, this ReAct+agentic stack achieves a 93% mission success rate with an average mission creation time of 96.96 seconds at a low decoding temperature, demonstrating that structured, multistep reasoning and tool use can deliver high reliability without blowing up latency.  

 By contrast, pure visionLLMs, even when multimodal and fairly large, tend to be evaluated on perceptual or questionanswer tasks rather than missionlevel outcomes. Sapkota and colleagues’ broader work on multimodal LLMs in domains like agriculture underscores the pattern: generalpurpose or domainadapted visionlanguage models excel at flexible perception and instruction following, but their performance is typically reported as accuracy on classification, detection, or description benchmarks, not as endtoend success in complex workflows. dblp In a benchmarking context like ezbenchmark, which is inspired by TPCH’s workloadcentric philosophy, that distinction matters. A visionLLM can certainly answer “What structures do we see in this tile?” or “Which parcels are likely orchards?” with impressive zeroshot competence, but those answers are rarely tied directly to operational metrics like “Did the mission achieve its analytic goal without reflight?” or “How many followup queries or human corrections were needed?” The agentic literature, especially around UAVs, starts from those operational questions and works backward to architecture.  CatalyzeX

 The Agentic UAVs survey by Sapkota, Roumeliotis, and Karkee makes that shift explicit. They define Agentic UAVs as systems that integrate perception, decisionmaking, memory, and collaborative planning to operate adaptively in real environments, with goaldriven behavior and contextual reasoning as firstclass design targets.  CatalyzeX In their taxonomy, visionLLMs and other multimodal models are enabling technologies inside a larger agentic stack rather than the entire solution. Perception components transform aerial imagery and other sensor data into structured representations; cognitive agents plan and replan missions; control agents execute actions; and communication agents manage interaction with humans and other UAVs across domains like precision agriculture, construction, disaster response, environmental monitoring, and inspection.  From an effectiveness standpoint, the survey argues that these agentic stacks surpass traditional UAV autonomy by improving mission flexibility, learning capacity, and systemlevel robustness, but they also incur more architectural complexity. For a benchmark like ezbenchmark or a spatiotemporal query engine like SpatialSky, this implies that evaluating “just the visionLLM” only tells part of the story; we also want metrics that capture how an agentic wrapper uses perception, memory, and planning to deliver reliable analytics over time.  CatalyzeX

 UAVCodeAgents sits at the intersection of these ideas and gives we quantitative hooks to work with. It exemplifies a multiagent ReAct framework where each agent is powered by an LLM or VLM but constrained by a structured action space: interpret imagery, reference map locations, synthesize mission code, revise plans, and coordinate with peers. The authors show that finetuning Qwen2.5VL7B on 9,000 annotated satellite images substantially improves spatial grounding, which is a direct nod to the strength of visionLLMs as perception cores.  Yet the headline numbers—93% success rate, roughly 97second planning times—are achievements of the full agentic system, not the VLM alone.  If we imagine swapping that ReAct framework into an ezbenchmark workload, the effectiveness metrics we would record are not only pixel or objectlevel accuracies but also how many reasoning–action iterations the agents need to converge, how often they recover from ambiguous instructions without human help, and how consistently they satisfy constraints akin to TPCH’s query semantics when operating over a drone scenes catalog.

 The broader survey of Agentic LLMs reinforces why that ReAct pattern has become so central. It distinguishes between “plain” LLM use—where the model simply maps prompts to outputs—and agentic use, where LLMs plan, call tools, manage memory, and interact with other agents in pursuit of goals. alphaxiv.org UAVCodeAgents is explicitly cited as an example of this agentic turn in UAV mission planning: multiagent ReAct plus visionlanguage grounding yields scalable, autonomous mission generation with minimal supervision. alphaxiv.org When we transfer that lens back to benchmarking, we get a natural threeway comparison. Pure visionLLMs are costeffective for singlestep perception and natural language querying; ReAct frameworks wrap those models in explicit “think–act–observe–think” loops that can interrogate data and tools; full agentic UAV architectures, as surveyed by Sapkota et al., extend this further by embedding ReActlike cycles into a distributed system that includes collaboration, persistent memory, and multimission learning.  alphaxiv.org  Each step up the ladder tends to increase implementation cost and complexity but also improves missionlevel robustness and adaptability in domains that look a lot like the use cases in SpatialSky and what we are sketching in ezbenchmark—multitile analytics, evolving spatiotemporal queries, and feedbackdriven missions over large areas.

 For the specific kinds of workloads in ezbenchmark and SpatialSky—workload chains over a spatial schema, spatiotemporal pattern detection, and comparative evaluation of alternative pipelines—the existing literature suggests a division of labor rather than a straight winner. VisionLLMs, especially when domaintuned like the Qwen2.5VL7B variant in UAVCodeAgents, serve as powerful perception and explanation modules, mapping imagery and schemalevel metadata into natural language and structured hints.  dblp ReAct frameworks, exemplified by UAVCodeAgents, convert that perception into iterative planning and tool use, achieving high mission success and bounded planning time.  Agentic UAV architectures, as surveyed by Sapkota and colleagues, frame everything as part of a larger ecosystem where agents can accumulate experience, coordinate across missions, and adapt to new tasks and domains.  CatalyzeX If we encode those three regimes as configurations in ezbenchmark—visionLLM only, visionLLM+ReAct controller, and full agentic stack—we can attach metrics that reflect what the literature actually measures: tasklevel accuracy and descriptive quality for the VLM, convergence behavior and missionsuccess rates for ReAct, and crossmission adaptability and systemlevel robustness for the agentic frameworks.  alphaxiv.org  CatalyzeX

 In that sense, incorporating ReAct and agentic metrics into ezbenchmark is less about chasing a trend and more about turning the UAV and agentic AI survey results into concrete benchmark dimensions. UAVCodeAgents gives us  model of how to quantify ReActbased mission planning performance in aerial scenarios, including success rates and planning time under different reasoning temperatures.  The Agentic UAVs survey gives us a taxonomy of capabilities—goaldriven behavior, contextual reasoning, collaborative planning—that we can translate into workloads and evaluation criteria at the analytics level.  CatalyzeX And the broader Agentic LLMs perspective explains why simply swapping in a bigger or better visionLLM will not give us the same systemlevel behavior as a ReAct or agentic framework; what matters is how the model is embedded in a loop of reasoning, action, and feedback. alphaxiv.org Together, they give us a roadmap for evolving ezbenchmark from a TPCHinspired catalog of queries into a testbed that can meaningfully compare visionLLMs, ReAct controllers, and full agentic UAV stacks on the very kinds of aerial analytics workloads embodied in our own repository and in systems like SpatialSky.

 The ReAct family of frameworks, where agents interleave explicit reasoning with concrete actions, has become one of the most natural ways to structure aerial drone analytics once we move beyond static perception into mission‑ and workflow‑level intelligence. In the UAV literature, we see this most clearly in the distinction between traditional “sense–plan–act” autonomy and what Sapkota and colleagues call Agentic UAVs: systems that integrate perception, decision‑making, memory, and collaborative planning into goal‑driven agents that can adapt to context and interact with humans and other machines in a loop, not just execute precomputed trajectories. ReAct‑style agents fit neatly into this picture as the cognitive core: they look at aerial data and task context, think through possible interpretations and actions in natural language or a symbolic trace, then call tools, planners, or control modules, observe the results, and think again. For drone image analytics, that “reason + act” cycle is where scene understanding, query planning, and mission evaluation start to blur together.

Sapkota et al.’s survey is useful precisely because it doesn’t treat this as a single pattern but as a spectrum of agentic architectures for UAVs. At one end are perception‑heavy agents where the “act” step is little more than calling specialized detectors or segmenters over imagery; the ReAct loop becomes a way to sequence image analytics: detect, reflect on the result, refine the region of interest, detect again, and so on. In the middle are cognitive planning agents that take higher‑level goals—“inspect all bridges in this corridor,” “prioritize hotspots near critical infrastructure”—and use ReAct loops to decompose them into analyzable subproblems, continuously grounding their reasoning in visual and geospatial feedback. At the far end are fully multi‑agent systems where different agents specialize in perception, planning, communication, and oversight, coordinating via shared memories and negotiation; here, ReAct is no longer a single loop but a pattern repeated inside each agent’s internal deliberation and in their interactions with each other. Across these types, aerial image analytics is both the substrate (what perception agents operate on) and a source of constraints (what planning and oversight agents must respect).

UAV‑CodeAgents by Sautenkov et al. is arguably the clearest instantiation of a multi‑agent ReAct framework for aerial scenarios. Built explicitly on large language and vision‑language models, it uses a team of agents that interpret satellite imagery and natural‑language instructions, then iteratively generate UAV missions via a ReAct loop: agents “think” in natural language about what they see and what the instructions require, “act” by emitting code, waypoints, or tool calls, observe the updated plan and environment, and then continue reasoning. A key innovation is their vision‑grounded pixel‑pointing mechanism, which lets agents refer to precise locations on aerial maps, ensuring that each act step is anchored in real spatial structure rather than abstract tokens. This is not just a conceptual nicety; in their large‑scale fire‑detection scenarios, the combination of multi‑agent ReAct reasoning and grounded actions yields a reported 93% mission success rate with an average mission creation time of 96.96 seconds at a lower decoding temperature, showing that we can get both reliability and bounded planning latency when the ReAct loop is carefully constrained.

If we step back and treat these works as a de facto “survey” of ReAct variants for drone analytics, a few archetypes emerge. Single‑agent ReAct patterns appear when a single vision‑language model is responsible for both scene understanding and action selection, often in simpler or more scripted environments. Multi‑agent ReAct, as in UAV‑CodeAgents, distributes reasoning and action across specialized agents—one may focus on interpreting imagery, another on code synthesis for trajectory generation, another on constraint checking—with the ReAct loop dictating both their internal thought and their coordination. Sapkota et al. broaden this further by embedding ReAct‑like cycles into a layered cognitive architecture where perception, cognition, and control agents all perform their own micro “reason + act” sequences, coordinated through shared memory and communication protocols. In all cases, the ReAct pattern is what allows these systems to treat aerial imagery not as a static input to a one‑shot model, but as a dynamic environment that agents can interrogate, test, and respond to.

For ezbenchmark, which is inheriting TPC‑H’s workload sensibility into drone image analytics, these ReAct variants suggest natural metrics to encode into the benchmark. UAV‑CodeAgents already gives u two: mission success rate and mission creation time under a multi‑agent ReAct regime. Sapkota et al. implicitly add dimensions like adaptability to new tasks and environments, collaborative efficiency among agents, and robustness under partial observability, all tied to how effectively agents can close the loop between reasoning and action in complex aerial scenarios. Translating that into ezbenchmark means we can, for each workload, not only measure traditional analytics metrics (accuracy, latency, cost) but also evaluate how different ReAct configurations perform when used as controllers or judges over the same scenes: how many reasoning–action iterations are needed to converge on a correct analytic conclusion, how sensitive mission‑level outcomes are to the agent’s decoding temperature, and how multi‑agent versus single‑agent ReAct architectures trade off between planning time and success rate.

Framing ReAct this way turns it into a first‑class axis in our benchmark rather than a hidden implementation detail. A workload in ezbenchmark could specify not just “find all overloaded intersections in this area” but also the agentic regime under test: a single vision‑LLM performing a ReAct loop over tools, a UAV‑CodeAgents‑style multi‑agent system, or a layered Agentic UAV architecture where oversight and planning are separated. The metric is then not only whether the analytic answer matches ground truth, but how the ReAct dynamics behave: convergence speed, stabiliuty under repeated runs, and resilience to minor perturbations in input or prompt. The survey‑style insights from Agentic UAVs and the concrete results from UAV‑CodeAgents together give u enough structure to define those metrics in a principled way, letting ezbenchmark evolve from a static TPC‑H‑inspired harness into a testbed that can actually compare ReAct frameworks themselves as part of the drone analytics stack.

 Cost–effectiveness is where the romantic idea of “just use a giant vision‑LLM” runs into the hard edges of drone operations. When we look for explicit economic comparisons between vision‑LLMs used directly on aerial imagery and more structured agentic frameworks, we quickly discover that the literature is still thin: most papers report computational and operational efficiency (latency, success rate, mission duration), but stop short of a full dollar‑per‑mission analysis. Still, the numbers they do provide already hint at how the trade‑offs play out when we try to build something like ezbenchmark into a realistic pipeline.

UAV‑CodeAgents is a useful anchor because it is unambiguously an agentic framework: a team of language and vision‑language model–driven agents using a ReAct loop to interpret satellite imagery, ground natural language instructions, and generate detailed UAV missions in large‑scale fire detection scenarios. Rather than asking a single vision‑LLM to go from pixels to trajectories, the system delegates: one agent reads the task and context, another reasons about waypoints in map space, and others refine plans through iterative “think–act” cycles, all grounded by a pixel‑pointing mechanism that can refer to precise locations on aerial maps. From a cost perspective, this is clearly heavier than a single forward pass through a monolithic VLM, but the paper quantifies why developers might accept that overhead: at a relatively low decoding temperature, UAV‑CodeAgents achieves a 93% mission success rate with an average mission creation time of 96.96 seconds for complex industrial and environmental fire scenarios. Those two numbers—success rate and planning latency—are effectively stand‑ins for mission‑level cost: fewer failed missions and sub‑two‑minute planning windows translate into fewer re‑flights and less human babysitting.

In contrast, work that relies on vision‑LLMs alone for aerial or satellite reasoning generally reports per‑task accuracy and qualitative flexibility, but not system‑level success metrics. A vision‑LLM that can answer “Where are the highest‑risk areas in this scene?” or “Which roofs look suitable for solar?” in a single forward pass is computationally attractive in isolation: one model, one call, no orchestration overhead. However, without an agentic layer to manage tools, refine outputs, and correct itself, any errors must be caught either by humans or by additional guardrail logic that is usually not part of the evaluation. What UAV‑CodeAgents implicitly shows is that we can treat the additional compute for multi‑agent reasoning as a kind of insurance premium: more tokens and more calls per mission, but dramatically higher odds that the resulting trajectory actually satisfies operational constraints. When we factor in the cost of failed missions—wasted flight time, re‑runs, delayed detection—the agentic system’s 93% success rate looks less expensive than it first appears.

None of this means that agentic frameworks are always cheaper in a narrow cloud‑bill sense. A pure vision‑LLM approach keeps our architecture simple and our per‑call overhead low. We can batch images, run them through a single VLM, and get scene descriptions or coarse analytics with predictable latency. If our benchmark only cares about perception‑level accuracy on static tasks, that simplicity is compelling. But once we move toward workload‑level benchmarking—chains of queries, mission‑like sequences, or “LLM‑as‑a‑judge” roles—errors propagate. A cheap VLM judgment that nudges a pipeline in the wrong direction can incur downstream costs far larger than the initial savings. UAV‑CodeAgents’ design, where agents iteratively reflect on observations and revise mission goals, is essentially an explicit acknowledgement that paying for more reasoning steps up front can reduce expensive mistakes later.

For ezbenchmark, which inherits TPC‑H’s focus on whole workloads rather than micro‑tasks, this suggests a specific way to think about cost‑effectiveness studies. Instead of trying to price each VLM token or GPU second in isolation, we treat the combination of “analytics accuracy + mission success + human oversight time” as our cost metric, and then compare three regimes: vision‑LLM alone, vision‑LLM embedded as a component in an agentic judge, and a full multi‑agent ReAct‑style framework like UAV‑CodeAgents wrapped around our catalog and tools. The existing literature gives us at least one anchor point on the agentic side—around 97 seconds of planning with 93% success for complex missions—while the vision‑LLM‑only side gives us per‑task accuracy but typically omits mission‑level reliability. A genuine cost‑effectiveness study in our setting would fill that gap, measuring not only GPU minutes but also re‑runs, operator interventions, and time to trustworthy insight over a suite of benchmark workloads

What’s missing in current research, and where ezbenchmark could be genuinely novel, is a systematic, TPC‑H‑style analysis that treats agentic frameworks and vision‑LLMs as first‑class design choices and quantifies their end‑to‑end economic impact on drone image analytics. UAV‑CodeAgents proves that multi‑agent ReAct with vision‑language reasoning can deliver high mission success with bounded planning time; our benchmark can extend that logic to analytics and judging: how many agentic reasoning steps, how many tool calls, and how many vision‑LLM passes are worth spending to get one unit of “better decision” from a drone scene. Framed that way, cost‑effectiveness stops being an abstract question about model sizes and becomes something our framework can actually measure and optimize.
