Autonomous Evolution of Reasoning LLMs
R-Zero represents a significant leap towards artificial superintelligence by enabling Large Language Models to self-evolve. Unlike traditional methods heavily reliant on human-curated data and labels for fine-tuning or reinforcement learning, R-Zero operates without any pre-existing tasks or human intervention. It sets up a co-evolutionary loop between a Challenger and a Solver, driving continuous improvement in reasoning.
The Challenger-Solver Co-Evolutionary Loop
R-Zero initializes a base LLM into two distinct roles: a Challenger and a Solver. The Challenger generates novel, challenging tasks, while the Solver attempts to solve them. Their interaction forms a self-improving curriculum. The Challenger is rewarded for creating tasks at the edge of the Solver's current capabilities, using an uncertainty reward based on solver self-consistency. The Solver is rewarded for successfully tackling these increasingly difficult tasks. This process leverages Group Relative Policy Optimization (GRPO) for training both models.

Robust Performance Across Diverse Reasoning Benchmarks
Our experiments showcase R-Zero's model-agnostic effectiveness, improving reasoning across various backbone LLMs (Qwen3-4B/8B-Base, OctoThinker-3B/8B). It demonstrates substantial gains on both mathematical (e.g., +6.49% on Qwen3-4B-Base) and general-domain reasoning benchmarks (e.g., +7.54% on Qwen3-4B-Base SuperGPQA/MMLU-Pro/BBEH average).

Understanding the Dynamics of Self-Evolution
An in-depth analysis confirms the critical roles of all R-Zero components: Challenger's RL training, repetition penalty, and task filtering. Disabling any of these leads to significant performance degradation. We also observe that the Challenger successfully generates progressively more difficult questions over iterations, but this increasing difficulty correlates with a drop in pseudo-label accuracy and an eventual performance collapse, particularly for smaller models.

Impact of Task Filtering (General AVG)
Disabling Task Filtering caused a >6-point drop in general-domain average, highlighting its crucial role in data quality and curriculum calibration.
The Iterative Collapse of Self-Evolving LLMs
Our analysis reveals that while R-Zero initially delivers significant performance improvements, this virtuous cycle does not continue indefinitely. After multiple iterations, we observe a consistent trend of performance degradation across all models, with smaller models collapsing earlier. This suggests an inherent instability or limitation within current self-improvement frameworks, driven by factors beyond just pseudo-label noise, potentially including model collapse from training exclusively on self-synthesized data.
- Performance degradation occurs after several iterations, especially for smaller models.
- Pseudo-label accuracy degradation is a factor, but not the sole cause.
- Likely points to a form of model collapse from training on self-synthesized data.
