Vision-Zero: Scalable VLM Self-Improvement via Strategic Gamified Self-Play (2509.25541v1)
Abstract: Although reinforcement learning (RL) can effectively enhance the reasoning capabilities of vision-LLMs (VLMs), current methods remain heavily dependent on labor-intensive datasets that require extensive manual construction and verification, leading to extremely high training costs and consequently constraining the practical deployment of VLMs. To address this challenge, we propose Vision-Zero, a domain-agnostic framework enabling VLM self-improvement through competitive visual games generated from arbitrary image pairs. Specifically, Vision-Zero encompasses three main attributes: (1) Strategic Self-Play Framework: Vision-Zero trains VLMs in "Who Is the Spy"-style games, where the models engage in strategic reasoning and actions across multiple roles. Through interactive gameplay, models autonomously generate their training data without human annotation. (2) Gameplay from Arbitrary Images: Unlike existing gamified frameworks, Vision-Zero can generate games from arbitrary images, thereby enhancing the model's reasoning ability across diverse domains and showing strong generalization to different tasks. We demonstrate this versatility using three distinct types of image datasets: CLEVR-based synthetic scenes, charts, and real-world images. (3) Sustainable Performance Gain: We introduce Iterative Self-Play Policy Optimization (Iterative-SPO), a novel training algorithm that alternates between Self-Play and reinforcement learning with verifiable rewards (RLVR), mitigating the performance plateau often seen in self-play-only training and achieving sustained long-term improvements. Despite using label-free data, Vision-Zero achieves state-of-the-art performance on reasoning, chart question answering, and vision-centric understanding tasks, surpassing other annotation-based methods. Models and code has been released at https://github.com/wangqinsi1/Vision-Zero.

Vision-Zero: Scalable VLM Self-Improvement via Strategic Gamified Self-Play
Motivation and Paradigm Shift
Vision-LLMs (VLMs) have achieved strong performance on multimodal reasoning tasks, but their scalability is fundamentally constrained by the reliance on human-curated datasets and annotation-intensive reinforcement learning pipelines. The Vision-Zero framework introduces a zero-human-in-the-loop paradigm for VLM self-improvement, leveraging strategic self-play in a visual social deduction game ("Who Is the Spy?") constructed from arbitrary image pairs. This approach eliminates the need for manual data labeling and expert-designed reward functions, enabling scalable, domain-agnostic training.

Strategic Game Environment and Data Construction
Vision-Zero operationalizes self-play through a multi-agent game environment. Each round consists of civilians and one spy, each assigned an image: civilians receive the original, while the spy receives a subtly modified version. The game proceeds in two stages:
- Clue Stage: Each agent provides a verbal clue about their image, with the spy aiming to blend in and civilians aiming to be informative yet non-revealing.
- Decision Stage: Civilians analyze all clues and vote to identify the spy.
This environment is highly strategic, requiring agents to reason about object attributes, spatial relations, and the intentions of other players. The input is simply an image pair, making the framework label-free and domain-agnostic. Datasets are generated via automated rendering (CLEVR), programmatic chart editing (ChartQA), and real-world image editing (ImgEdit), with costs orders of magnitude lower than traditional annotation pipelines.

Iterative Self-Play Policy Optimization (Iterative-SPO)
To achieve sustainable performance gains and avoid equilibrium stagnation, Vision-Zero introduces Iterative-SPO, an alternating optimization algorithm:
- Clue Stage: Self-play policy optimization with zero-sum rewards based on votes received, regularized by role advantage estimation (RAE) to mitigate information asymmetry.
- Decision Stage: RL with verifiable rewards (RLVR), using group-normalized advantage-weighted log-likelihood and KL regularization.
The training alternates between stages based on moving averages of accuracy and "n/a" rates, switching when stagnation or saturation is detected. This dynamic gating prevents premature convergence and ensures continuous skill escalation.

Empirical Results and Performance Analysis
Vision-Zero was evaluated on Qwen2.5-VL-7B, InternVL3-8B, and InternVL3-14B across 14 benchmarks in reasoning, chart/OCR, and vision-centric domains. Key findings include:
- Sustained Performance Growth: Win rates against reference models increased from 50% to 71% over training, with substantial growth in token length, indicating deeper reasoning.
- Generalization: Models trained in Vision-Zero environments (CLEVR, Chart, Real-World) achieved 2.8–3% higher accuracy on MathVista, MathVision, and LogicVista compared to baselines trained on large annotated datasets.
- Negative Transfer Mitigation: Unlike RLVR-trained baselines, Vision-Zero models did not suffer performance drops on chart/OCR tasks when post-trained for reasoning, demonstrating effective multi-capability learning.
- Cost Efficiency: Dataset construction required only tens of GPU hours and minimal financial cost, compared to months of manual annotation for RLVR baselines.

Implementation Details
Vision-Zero is implemented using the VLM-R1 codebase, supporting distributed training with FlashAttention-2 and DeepSpeed ZeRO-3. Key hyperparameters include civilians, for clue-stage rewards, for decay coefficients, and KL regularization weights of $0.04$. Stage-switching thresholds are empirically set to ensure robust alternation between clue and decision stages. Training is performed for 100–150 iterations with batch sizes of 1024.
Dataset generation pipelines are fully automated:
- CLEVR: Procedural rendering with Blender, random object attribute changes.
- ChartQA: Chart parsing and editing via GPT-4o, followed by Python-based chart rendering.
- Real-World: Image editing using advanced multimodal models (ChatGPT, Gemini).
Prompts are dynamically templated for role-aware generation, enforcing behavioral separation and supporting batched multi-agent simulation.
Theoretical and Practical Implications
Vision-Zero demonstrates that strategic self-play in a multimodal game environment can drive scalable, generalizable VLM self-improvement without human supervision. The framework is robust to domain shifts, supports multi-capability learning, and is highly cost-efficient. The alternating optimization of Iterative-SPO is empirically superior to single-mode training, providing a stable learning signal and preventing role collapse or stagnation.
Theoretically, Vision-Zero extends self-play paradigms from board and language games to the multimodal domain, leveraging competitive dynamics to surpass the knowledge ceiling imposed by human-annotated data. Practically, it enables rapid, low-cost development of VLMs for diverse real-world applications, including reasoning, chart analysis, and visual understanding.
Future Directions
Potential future developments include:
- Extension to more complex game environments and multi-image scenarios.
- Integration with agentic frameworks for embodied reasoning and action.
- Exploration of emergent communication and theory-of-mind capabilities in multi-agent VLMs.
- Scaling to larger models and datasets, leveraging synthetic data generation for open-ended skill acquisition.
Conclusion
Vision-Zero establishes a new paradigm for VLM self-improvement, combining strategic gamified self-play with domain-agnostic, label-free data construction and a robust alternating optimization algorithm. It achieves state-of-the-art performance across reasoning, chart/OCR, and vision-centric tasks, while dramatically reducing training costs and mitigating negative transfer. Vision-Zero provides a scalable, flexible, and economical solution for advancing VLM capabilities in both research and deployment contexts.

Overview
This paper introduces Vision-Zero, a new way to train vision-LLMs (VLMs) without using expensive human-made labels. A VLM is a computer system that looks at images and reads text to answer questions or explain what it sees. Vision-Zero teaches these models by turning learning into a visual “Who Is the Spy?” game, so the model improves by playing—no humans needed to prepare data or correct answers.
What are the main questions?
The researchers wanted to know:
- Can a VLM teach itself to reason better using games instead of human-labeled data?
- Can this game work with almost any kind of image (charts, simple shapes, real photos) and still help the model?
- How do we keep improving the model over time, instead of getting stuck at “good enough”?
- Can this label-free training match or beat methods that rely on large, expensive datasets?
How does Vision-Zero work?
The game: “Who Is the Spy?”
Think of a strategy game like Mafia or Among Us, but with images:
- Several “civilian” players each get the same image.
- One “spy” gets a slightly different image (maybe a color changed, an object added or removed, or a number swapped in a chart).
- In the clue stage, players take turns giving short descriptions of their image. The spy tries to sound normal and hide the difference. Civilians try to be accurate without giving away too much.
- In the decision stage, civilians vote on who they think the spy is, based on everyone’s clues and their own image.
Because the model plays all roles, it generates its own training examples and gets feedback from the game’s outcome.
Training without human labels
Vision-Zero only needs pairs of images: one original and one slightly edited. No labels like “correct answer,” “object name,” or “bounding boxes” are required. The game itself produces feedback:
- If civilians correctly identify the spy, they get positive points.
- If they pick the wrong person, they lose points.
- The spy earns points by tricking civilians. This is called “verifiable rewards” because the game can check whether votes were correct.
Alternating training to keep improving
The team created a two-part training method called Iterative-SPO:
- Self-play phase (clue stage): The model learns how to give better clues. Rewards are “zero-sum,” meaning one side’s gain is the other side’s loss—this encourages smarter strategies.
- RLVR phase (decision stage): The model learns to judge clues and vote correctly. RLVR stands for reinforcement learning with verifiable rewards, which means the model receives clear points for correct or uncertain answers and penalties for wrong ones.
They switch between these phases based on how well the model is doing. If identifying the spy gets too easy, they train the clue stage to make the game harder. If it gets too hard or the model guesses too much, they train the decision stage. This back-and-forth avoids getting stuck and keeps progress steady.
Works with many types of images
Vision-Zero is “domain-agnostic,” which means it can use:
- Synthetic scenes with simple shapes (CLEVR)
- Charts (bar, line, pie) with numbers swapped
- Real-world photos slightly edited
These can be created quickly and cheaply with modern image-editing tools.
What did they find, and why is it important?
The main results show:
- Better reasoning: Models trained with Vision-Zero improved on multiple reasoning and math-related benchmarks, beating or matching methods that use large, human-labeled datasets.
- Generalization: Even though the game doesn’t directly teach math, the skills learned—careful observation, logical clues, spotting inconsistencies—carry over to math and logic tasks.
- Fewer trade-offs: Other methods often improve one skill (like math) but hurt others (like understanding charts). Vision-Zero improved several abilities at once and reduced these negative side effects.
- Sustainable growth: The model keeps getting better over time, rather than hitting a plateau, thanks to the alternating training phases.
- Low cost: Instead of months of human labeling, Vision-Zero uses simple image edits and game outcomes. It’s far cheaper and faster to build datasets this way.
In short, Vision-Zero shows that self-play with smart game design can produce strong, broad improvements without human labels.
Why does this matter?
- Lower barriers: Training powerful VLMs no longer requires massive, expensive, hand-labeled datasets.
- Faster progress: Teams can build new, specialized datasets quickly using image edits and still get good results.
- Broader skills: Because it blends visual detail, language, and strategy, Vision-Zero strengthens multiple abilities at once—reasoning, spatial understanding, OCR for text in images, and more.
- Practical impact: This approach could help create smarter assistants for education, data analysis, science, and everyday tools that need to understand both pictures and words.
Overall, Vision-Zero shows a promising path toward “zero-human-in-the-loop” training: models that improve themselves through play, becoming more capable while saving time, money, and effort.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a concise list of what remains missing, uncertain, or unexplored in the paper, articulated to be actionable for future research.
- Difficulty scaling of the environment is not operationalized: there is no mechanism to progressively increase the subtlety or number of visual differences, the number of rounds, or the complexity of strategic constraints; alternation between stages adjusts agent behavior but not task difficulty itself.
- Ambiguity and quality control of edited images are unaddressed: no automatic validation ensures a single, visible, unambiguous difference per pair (or that differences are not inadvertently trivial or undetectable), which risks noisy rewards and mislabelled “spy” rounds.
- Reward design vulnerability to collusion or reward hacking: since rewards depend on votes from model copies, agents could learn to coordinate (e.g., under-disclose or over-disclose) to inflate group rewards; anti-collusion mechanisms, opponent diversity, or audit checks are not explored.
- Lack of theoretical guarantees: Iterative-SPO has no convergence, stability, or monotonic improvement guarantees; conditions under which the alternating scheme avoids equilibrium stagnation or oscillations are not analyzed.
- Sensitivity to hyperparameters is unknown: no systematic sweeps or robustness analysis for β, λ, α, KL weights, group normalization parameters, and phase-switch thresholds; their impact on performance and stability remains unclear.
- Verifiable signals are confined to the decision stage: the clue stage relies solely on peer voting; there are no semantic consistency checks of clues against ground-truth diffs (e.g., automated object/attribute detectors), leaving truthfulness and relevance of clues unverified.
- Token length as a proxy for reasoning quality is unvalidated: longer outputs are reported, but the relationship to actual reasoning correctness, structure, or faithfulness is not quantified; more rigorous reasoning metrics are needed.
- Statistical rigor is limited: results lack confidence intervals, multiple seeds, or variance reports; significance of the 2–3% gains versus noise is unclear across tasks and models.
- Baseline comparability is imperfect: some baselines are missing or reported from original papers under different settings; compute budgets, data sizes, and training recipes are not controlled, limiting fairness of comparisons.
- Scalability to larger models and longer training horizons is unknown: only 7B–14B models and ~100 iterations are tested; scaling laws, sample efficiency, and asymptotic behavior with more data/compute remain unexplored.
- Opponent diversity is narrow: self-play occurs against current/reference policies without a league or archive; whether a population-based or curriculum league improves robustness and prevents overfitting is an open question.
- Fixed game configuration is unablated: number of civilians (n_c=4), number of clue rounds (two), and role assignment strategies are fixed; the effect of varying these parameters on learning dynamics and transfer is not studied.
- Environment difficulty gating is heuristic: phase switching relies on hand-tuned thresholds (accuracy, “n/a” rate) without principled derivation or generalization evidence across datasets/models; alternative gating signals are not tested.
- Transfer mechanisms are not causally identified: the paper shows generalization gains but does not analyze which learned behaviors (e.g., inconsistency detection, visual grounding, strategic discourse) drive improvements on math/reasoning benchmarks.
- Robustness to imperfect or adversarial inputs is untested: performance under occlusions, compression artifacts, multiple simultaneous edits, or “no-diff” pairs (requiring systematic “n/a” responses) is unknown.
- Potential degradation of truthfulness and honesty is unmeasured: the spy role incentivizes deception; impacts on truthfulness, safety, and alignment in general-purpose use are not evaluated; countermeasures (e.g., honesty constraints, truthfulness rewards) are absent.
- Domain coverage is limited to static images: there is no exploration of video, temporal reasoning, embodied tasks, or interactive environments; extension to multimodal sequences (vision+audio) and longer-horizon games is open.
- Data generation relies on proprietary tools (Gemini/ChatGPT): reproducibility and licensing concerns exist; open-source pipelines and quantitative quality audits for edits are not provided.
- Ground-truth “spy” labels are programmatic but not semantically verified: while the spy index is known, no automated check confirms that the modified attribute is the one agents should reason about (e.g., multiple unintended differences).
- Role parameterization is unclear: it is not specified whether roles share parameters or use role-specific heads/policies; the impact of role-specific architectures versus shared weights on learning and stability is not explored.
- KL regularization and reference policy choice are under-specified: how the reference distribution is updated or selected, and its effect on exploration/exploitation and degeneration avoidance, is not ablated.
- Negative transfer analysis is shallow: while some mitigation is reported, a broader audit across safety, hallucination rates, instruction following, and OCR fidelity (especially under domain shifts) is missing.
- Difficulty curriculum via environment generation is absent: no algorithm adapts edit magnitude, object count, distractor density, or textual constraints to match agent skill; a principled curriculum could improve sustained growth.
- Failure modes are not dissected: there is no taxonomy or qualitative analysis of incorrect votes (e.g., visual grounding errors, linguistic misinterpretations, strategic misjudgments), which would inform targeted improvements.
- Compute and energy accounting is opaque: claims of “tens of GPU hours” lack full details (hardware type, fp16/bf16 settings, memory footprint, optimizer schedules), hindering reproducibility and cost-benefit analyses.
- Cross-lingual and cultural generalization is untested: how clue/vote strategies transfer across languages, cultural priors, and diverse visual domains remains unknown.
- Integration with RLHF/SFT is unexplored: how Vision-Zero complements human-aligned post-training (e.g., mixing self-play with RLHF or instruction tuning) and its effects on alignment and utility are open.
- Evaluation relies partly on GPT-based scoring without human validation: the qualitative improvements in reasoning are assessed by an external model; human studies or grounded rubrics are missing.
- Data leakage risks are unaddressed: potential unintended cues (filenames, metadata, encoding artifacts) that reveal the spy or civilian identity are not audited or sanitized.

Cross-cutting feasibility notes
- Transfer assumptions: The paper shows generalization from spy-game training to downstream reasoning/chart/OCR tasks with modest but consistent gains; transfer to safety-critical domains will require domain-faithful edits, stronger validation, and uncertainty calibration.
- Data generation: Success depends on generating subtle, domain-relevant image edits. For specialized fields (e.g., medical, satellite), high-fidelity simulators or expert-in-the-loop editing may be necessary.
- Compute and ops: Although cheaper than human labeling, Vision-Zero still needs GPU time and RL plumbing (self-play orchestration, KL regularization, reference policies, stage switching).
- Safety and governance: The competitive setup can incentivize deceptive strategies; alignment, red-teaming, and guardrails (e.g., calibrated “n/a” responses) are essential before real-world deployment.
- IP and privacy: Ensure rights to edit and process images; adopt privacy-preserving pipelines for sensitive enterprise data.
