Agent0-VL: Exploring Self-Evolving Agent for Tool-Integrated Vision-Language Reasoning (2511.19900v1)
Abstract: Vision-language agents have achieved remarkable progress in a variety of multimodal reasoning tasks; however, their learning remains constrained by the limitations of human-annotated supervision. Recent self-rewarding approaches attempt to overcome this constraint by allowing models to act as their own critics or reward providers. Yet, purely text-based self-evaluation struggles to verify complex visual reasoning steps and often suffers from evaluation hallucinations. To address these challenges, inspired by recent advances in tool-integrated reasoning, we propose Agent0-VL, a self-evolving vision-language agent that achieves continual improvement with tool-integrated reasoning. Agent0-VL incorporates tool usage not only into reasoning but also into self-evaluation and self-repair, enabling the model to introspect, verify, and refine its reasoning through evidence-grounded analysis. It unifies two synergistic roles within a single LVLM: a Solver that performs multi-turn tool-integrated reasoning, and a Verifier that generates structured feedback and fine-grained self-rewards through tool-grounded critique. These roles interact through a Self-Evolving Reasoning Cycle, where tool-based verification and reinforcement learning jointly align the reasoning and evaluation distributions for stable self-improvement. Through this zero-external-reward evolution, Agent0-VL aligns its reasoning and verification behaviors without any human annotation or external reward models, achieving continual self-improvement. Experiments on geometric problem solving and visual scientific analysis show that Agent0-VL achieves an 12.5% improvement over the base model.

Agent0-VL: Self-Evolving Tool-Integrated Vision-Language Reasoning
Introduction and Motivation
Agent0-VL addresses limitations in current open-ended vision-language agents, specifically their dependence on human-annotated supervision and the unreliability of text-only self-evaluation mechanisms, which frequently induce hallucinations in evaluation and reasoning. The core innovation of Agent0-VL is the introduction of a unified agent framework that enables self-evolving reasoning through fully integrated tool use—both during reasoning and in the model's own stepwise verification and repair. This advances prior approaches in self-improvement and tool-integrated reasoning by closing the loop with tool-grounded self-correction, removing the need for external reward or annotation.
System Architecture and Learning Paradigm
Agent0-VL is realized as a single LVLM that bifurcates its operation into two internal modes: the Solver—which performs multi-turn, tool-integrated reasoning—and the Verifier—which evaluates and critiques the Solver's actions via tool-grounded evidence, providing interpretable, dense feedback and repair guidance. Both modes are governed by a shared parameterization and optimized throughout a Self-Evolving Reasoning Cycle (SERC). The SERC is structured hierarchically: within each training cycle, Agent0-VL rolls out multimodal reasoning trajectories, the Verifier audits each step with external tools as necessary, and on detecting low-confidence, injects local, minimal repairs which the Solver then integrates into corrected rollouts.
Figure 1: The framework alternates unified policy between the Solver (reasoning/tool calls) and Verifier (generative verification and rewards), forming a closed self-improving learning loop.
Reinforcement is achieved without recourse to static, externally provided reward signals. Instead, rewards are generated based on stepwise factual correctness, semantic alignment, and tool-based validation, with regularization to guarantee alignment between solving and verifying distributions. Policy optimization is performed with Group Relative Policy Optimization (GRPO), effectively leveraging relative advantage among a group of trajectories to stabilize training and tune stepwise corrections.
Self-Evolving Reasoning Cycle and Repair Operation
The core iterative loop underlying Agent0-VL couples tool-integrated multimodal reasoning with introspective verification and precise local repair. Upon hypothesis or answer generation by the Solver, the Verifier inspects each computational trajectory phase using tools for evidence checking. Suboptimal or ambiguous reasoning triggers a confidence-gated mechanism: only when the Verifier's certainty falls below a prescribed threshold does the agent initiate a minimal patch, thus limiting unnecessary or redundant repair and encouraging conservative, high-evidence updates.

This cycle continually aligns the solving and verifying heads, enforcing self-consistency and enhancing both factual reliability and the agent's ability to generalize across domains. The method is robust to noise accumulation since verification is dynamically grounded in external tool evidence, not mere linguistic plausibility.
Empirical Evaluation
Agent0-VL undergoes extensive evaluation across a heterogeneous suite of seven vision-language reasoning benchmarks, including MathVerse, MathVision, MathVista, WeMath, HallusionBench, ChartQA, and MMMU. Comparative studies establish Agent0-VL's dominance over both open-source and closed-source state-of-the-art LVLMs in reasoning-centric and general multimodal settings. Specifically, Agent0-VL-7B demonstrates a 12.5% improvement over its Qwen2.5-VL-7B base model, while Agent0-VL-8B surpasses closed-source models, notably GPT-4o, on challenging math and perception benchmarks.
Performance gains are particularly strong in multi-step mathematical and visual analysis domains, with the framework yielding an 18.1% improvement on math-centric benchmarks due to its ability to validate and repair multistage symbolic calculation and visual interpretation. The performance benefits accrue monotonically with additional SERC iterations, showing consistent, stable self-improvement curves without reward collapse or degeneration.

Figure 4: Self-evolving reasoning workflow: error made by the Solver is pinpointed by Verifier, self-repair is triggered, and corrected logic leads to the right answer.
Case Analysis: Multifaceted Reasoning and Tool Usage
Qualitative case studies emphasize the generality of the approach. Agent0-VL dynamically invokes mixed toolchains (e.g., image cropping, code execution for math problems, visual question answering) within its reasoning process:
- In single-step image reasoning, the agent employs vision manipulation tools to isolate image regions critical for fact extraction, then integrates resulting observations into its textual chain-of-thought.
- In geometric or scientific analysis, the agent decomposes visual input, performs symbolic computation with code tools, and validates results numerically—achieving both interpretability and correctness.
- As a stepwise process Verifier, the model demonstrates granular error localization and process-level critique, outperforming contemporaries that either lack grounding or cannot introspect beyond final-answer correctness.

Implications and Future Directions
Agent0-VL establishes a scalable, annotation-free template for vision-language agent self-improvement, setting a new state-of-the-art in open vision-language tool reasoning and compositional process verification. Explicit integration of external tools during both reasoning and self-evaluation/repair decouples progress from annotation bottlenecks and enhances interpretability, transparency, and factual correctness.
Subsequent research might explore hierarchical tool orchestration, more sophisticated confidence-driven exploration policies, curriculum-based self-generation, and integration with planning for long-horizon tasks. Its process-level reward modeling is generalizable, as demonstrated by outperformance of the built-in Verifier when used as a reward model for external policies. Thus, the blueprint provided by Agent0-VL may facilitate advances in scalable RLHF for vision-language and other multimodal domains, especially where external labels or human oversight are impractical.
Conclusion
Agent0-VL demonstrates that fully unified reasoning, verification, and self-repair via tool integration and self-aligned reinforcement drives superior performance and robustness in multimodal agents. The innovations in policy alternating architecture, confidence-gated repair, and tool-grounded process rewarding yield both strong empirical results and practical pathways for further refinement and generalization in AI agents. Agent0-VL thus represents an instructive reference point for future developments in multimodal RL and self-improving agents operating in open-ended, partially observable environments.

What is this paper about?
This paper introduces Agent0‑VL, a smart computer program that can look at pictures and read text, then figure things out step by step. Unlike many models that depend heavily on people to label right and wrong answers, Agent0‑VL teaches itself to get better over time. It does this by using helpful tools (like calculators or code) not only while solving problems, but also while checking and fixing its own work.
What questions does it try to answer?
To make the ideas clear, here are the main questions the researchers wanted to explore:
- How can a vision‑LLM improve its reasoning without relying on human‑provided labels or external reward judges?
- Can using tools during both “thinking” and “checking” reduce mistakes like visual misunderstandings or math errors?
- Will a model that learns to verify and repair its own steps get steadily better over multiple training rounds?
- Can the model’s “checker” be reused to help other models pick better solutions?
How did the researchers approach the problem?
They built Agent0‑VL with two “jobs” inside one model and a repeated practice loop that helps it learn on its own.
Two roles inside one model: Solver and Verifier
- Solver: Think of this as the student. It reads the question, looks at the image, and works through the solution step by step. If needed, it calls tools—like running simple code, measuring, calculating, or reading values from charts—to make sure the steps are grounded in facts and numbers.
- Verifier: Think of this as a coach. It reviews each step the Solver took, checks facts (also using tools), gives a score for correctness, a confidence level (how sure it is), and a short explanation of what might be wrong. If confidence is low, the Verifier suggests how to fix the mistake.
This setup is like doing homework with a calculator and a measuring tool, then having a coach point out errors and explain how to improve.
Using tools during both thinking and checking
Many models only “think in words” (text) when solving and checking. That can lead to “hallucinations,” where the model guesses something that sounds right but doesn’t match the picture or the math. Agent0‑VL avoids this by:
- Calling tools during solving to compute exact numbers, read chart values, or perform geometry calculations.
- Calling tools during checking to verify each step with real evidence, not just words.
The Self‑Evolving Reasoning Cycle (SERC)
Agent0‑VL trains in two phases and loops through them:
- Warm‑up with supervision (SFT): It learns the basic format of using tools and how to write and check step‑by‑step solutions.
- Practice with self‑feedback (RL): It repeatedly:
- Solves tasks while using tools.
- Verifies each step, scoring correctness and confidence.
- Repairs low‑confidence steps with guided fixes.
- Gives itself “process rewards” based on how correct and well‑verified each step was.
For the RL part, they use something called Group Relative Policy Optimization (GRPO). In simple terms, the model tries many solution paths and then favors those that perform better than the group’s average, while keeping changes stable and safe.
You can think of SERC like training for a sport:
- Inner loop: Practice one routine, get feedback from your coach, fix weak parts.
- Outer loop: Update your overall strategy based on which routines performed better than average.
What did they find?
The model was tested on several visual reasoning benchmarks (like math problems with diagrams, chart reading, and scientific questions). Here’s what stood out:
- Clear performance gains: Agent0‑VL improved about 12.5% over its base model on average. The larger 8B version beat many strong open‑source models and even matched or surpassed closed‑source systems on some tasks (like MathVista, HallusionBench, and ChartQA).
- Steady improvement over iterations: Training in multiple rounds led to consistent gains each time. The model didn’t just get lucky once—it kept getting better.
- Fewer hallucinations: Using tools to check facts reduced mistakes where the answer sounded plausible but didn’t match the image or the math.
- Important parts matter: Removing tool use, the repair step, or the self‑evolving loop made the model worse. This shows each piece—solving with tools, verifying with tools, and repairing low‑confidence steps—works together to boost performance.
- Useful to other models: The Verifier can be reused as a “process reward model” (a smart scorer of solution steps) to help other vision‑LLMs pick better answers during test time. This gave those models an average 7.3% boost.
Why does this matter?
- Less dependence on human labels: Agent0‑VL shows that a model can keep improving without needing people to label tons of data. That makes training more scalable and affordable.
- More trustworthy reasoning: When a model checks itself using tools, it’s more likely to give accurate answers—especially for tasks involving numbers, geometry, or charts.
- Reusable checks: The Verifier is like a portable coach. Other models can use it to select better solutions, even if they weren’t trained with Agent0‑VL.
Simple takeaways
- Think, check, repair: Agent0‑VL solves problems, double‑checks with tools, and fixes low‑confidence steps. This loop helps it learn from its own mistakes.
- Tools reduce guesswork: Calculators, code, and visual measurements make reasoning concrete rather than just “wordy.”
- Practice makes progress: With repeated self‑guided practice, the model steadily improves across math, charts, and scientific reasoning.
- Shared coaching helps everyone: The Verifier can help other models pick stronger answers, spreading the benefits of careful, tool‑grounded checking.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a single, focused list of what remains missing, uncertain, or unexplored in the paper. Each point is framed to be actionable for follow-up research.
- Ambiguity in “zero external rewards”: the training objective includes a final outcome reward (Eq. 7), but the paper does not clarify whether this uses ground-truth answers (external supervision) or is disabled; concrete specification and experiments with vs. are missing.
- Unspecified and sometimes undefined notation and components impede reproducibility (e.g., in Eq. 5, “EE” and “RA” in Algorithm 1, role-gating mechanics, and broken/math typos across equations).
- Confidence calibration is assumed but not validated: the Verifier’s confidence gates repairs, yet no calibration metrics (e.g., ECE/Brier score), reliability diagrams, or temperature-tuning procedures are reported; robustness of gating under distribution shift remains unknown.
- Repair penalty design () is under-specified: how “unnecessary repairs” are detected, how penalty magnitudes are chosen, and their sensitivity to task/domain are not analyzed.
- Tool selection policy is underspecified: how the agent chooses which tool to call, when to call, and how to sequence multi-tool pipelines (e.g., solver vs. verifier tool orchestration) lacks formalization and ablation.
- Tool inventory and capabilities are unclear for vision tasks: beyond “Python code,” the paper does not detail vision-specific tools (e.g., OCR, detection, segmentation, chart parsers) or their APIs, coverage, accuracy, and error modes.
- Robustness to tool failures/noise is not evaluated: the agent’s behavior under erroneous, delayed, adversarial, or missing tool outputs is unstudied; failure injection and recovery strategies are absent.
- Safety and security of tool execution are not addressed: no sandboxing, resource isolation, permission controls, or mitigations against malicious code/data returned by tools are described.
- Data decontamination is unreported: the SFT dataset sources include known benchmarks (e.g., MM-Eureka, Retool) and possibly overlaps with evaluation sets; there is no contamination audit, split-level isolation, or leakage analysis.
- Reliance on “GPT-5” and Qwen2.5-VL-72B as teachers is opaque: teacher model configurations, availability, prompt templates, and quality checks for auto-generated trajectories are not provided; reproducibility and licensing are unclear.
- Compute, efficiency, and cost are not quantified: the overhead of multi-turn tool calls, verifier passes, self-repair loops, and RL iterations (wall-clock time, GPU hours, memory, tool latency) is not reported; sample efficiency studies are absent.
- Reward hacking risks are not assessed: alignment between Solver and Verifier distributions could incentivize superficial agreement; there is no adversarial analysis of reward exploitation, mode-collapse, or shortcutting (e.g., language priors masquerading as tool-grounding).
- Convergence and stability lack theoretical or empirical guarantees: GRPO with dual roles has no formal convergence analysis; long-horizon evolution (>3 iterations), oscillations, or catastrophic forgetting of perception are untested.
- Limited evaluation domains: tasks focus on math, charts, and hallucination; generalization to other modalities (video, audio), embodied or interactive environments (robotic control, web navigation), or real-world noisy settings is untested.
- No comparison to two-model architectures: the unified Solver–Verifier policy is not benchmarked against specialized or decoupled models (separate PRM, or separate solver and verifier) to quantify interference vs. benefits.
- Missing baselines on alternative RL algorithms: only GRPO is used; comparisons to PPO, VPG, DPO/sequence-level preference optimization, and off-policy methods (e.g., SAC) are absent, as are credit-assignment studies for process vs. outcome rewards.
- Step-level reward design is not validated: the weighting of tool correctness, semantic reliability, and KL alignment () lacks sensitivity analyses; cross-task tuning and generality are unproven.
- PRM evaluation lacks ground-truth correlation: the Verifier’s step-wise scores are not validated against labeled intermediate correctness or human judgments; rank correlations, ROC/AUC, or agreement analyses are missing.
- Best-of-N (BoN) gains may conflate sampling with evaluation: improvements using the Verifier as a PRM are reported for BoN but not top-1; disentangling selection bias from genuine reasoning improvement is not done.
- Error analysis and failure taxonomy are thin: beyond a single case paper, there is no systematic categorization of failure modes (e.g., visual misreads, numeric errors, tool misuse, repair misfires) or actionable diagnostics.
- ChartQA/HallBench improvements are modest and unexplained: the paper does not analyze why certain domains benefit less or what bottlenecks (vision tooling, parsing) limit gains; targeted interventions are not proposed.
- Role-switching mechanics are not stress-tested: the conditions, frequency, and costs of alternating between Solver and Verifier are not profiled; potential interference or role confusion is unquantified.
- Outcome vs. process reward trade-offs are unstudied: the balance parameter (Eq. 7) is introduced without tuning studies; how process rewards alone perform vs. combined rewards remains unclear.
- Generalization across languages and formats is unknown: cross-lingual performance, non-English benchmarks, and robustness to varied prompt styles or layouts (e.g., handwritten math, scanned charts) are untested.
- Dataset construction and curation details are missing: filtering, deduplication, diversity metrics, tool-augmented label quality, and license compliance for the 200k SFT and 40k RL datasets are not documented.
- Ethical and environmental impacts are not considered: energy footprint, carbon cost of multi-iteration RL with tool calls, and responsible use of executable tooling are not discussed.

- Use case: Visual reasoning over traffic dashboards and camera feeds
- What: Verify computed KPIs in dashboards; reconcile counts from charts with observed video/image samples; trigger plan “self-repair” when inconsistencies arise.
- Tools/products/workflows: VMS/CCTV ingestion; spatiotemporal analytics; incident response playbooks.
- Assumptions/dependencies: Video privacy and retention policies; edge compute for latency.
- Sector: Retail/Logistics
- Use case: Shelf and planogram compliance with step-wise verification
- What: Compare store shelf images to planograms; compute deviations; propose corrective steps; self-improve on store-specific layouts without annotated labels.
- Tools/products/workflows: Planogram parsers; inventory connectors; field-ops apps.
- Assumptions/dependencies: Store variability; occlusions; data-sharing agreements.
- Sector: General AI Infrastructure
- Use case: “Self-Evolving Agent Platform” for domain-specific LVLMs
- What: Offer SERC-based training as a managed service for enterprises to build domain-adapted, tool-grounded self-improving agents with zero external rewards.
- Tools/products/workflows: GRPO training loops; tool orchestration; evaluation harnesses; governance and audit.
- Assumptions/dependencies: Significant compute; safety policies for tool calls; monitoring for evaluation drift.
Notes on Cross-Cutting Assumptions and Dependencies
- Tooling: Reliable access to external tools (Python, OCR, chart parsers, retrieval, domain calculators, GIS/CAD/EDA/medical APIs) and a secure, sandboxed execution environment.
- Data and domain shift: Performance outside math/chart/visual scientific domains depends on domain-specific corpora and tools; additional SFT/RL may be required.
- Compute and latency: BoN selection, verification, and iterative self-repair add cost/latency; batching and caching strategies may be necessary.
- Safety and compliance: Regulated sectors (healthcare, finance, critical infrastructure) require validation, auditability, and adherence to standards; human oversight is essential.
- Interpretability: Structured critiques and confidence scores can aid adoption but may need domain-tailored templates and thresholds.
- IP/licensing: Use of base models, teacher models, datasets, and third-party tools must respect licenses and data governance.
