Agent0 is a fully autonomous framework that enables large language model agents to evolve without external data by using a multi‑step co‑evolution process. It pits a curriculum agent against an executor agent, both derived from the same base LLM, where the curriculum agent creates increasingly challenging tasks and the executor learns to solve them. By integrating external tools into the executor’s workflow, the system creates a self‑reinforcing cycle that continuously generates high‑quality curricula, leading to significant gains in reasoning performance—an 18% improvement on mathematical reasoning and 24% on general reasoning for the Qwen3‑8B‑Base model.

The paper argues that large language models need adaptive reasoning rather than fixed reasoning budgets. It shows that over‑reasoning leads to high computational cost without accuracy gains, while under‑reasoning results in incorrect or incomplete solutions. The authors evaluate these failure modes on MATH‑500 and the GAIA benchmark, highlighting the need for dynamic reasoning allocation in agentic AI systems.

CoSkill introduces a unified multi‑agent reinforcement learning framework that jointly trains a Reasoning Agent and a learnable Meta‑Skill Agent over a hierarchical skill library. By treating the meta‑skill workflow as a trainable agent and sharing a single backbone, CoSkill enables end‑to‑end co‑adaptation, allowing the Reasoning Agent to condition actions on retrieved task and step skills while the Meta‑Skill Agent refines those skills based on task performance. Experiments on ALFWorld and WebShop demonstrate that CoSkill outperforms prior skill‑based and RL baselines, achieving higher success rates and improved sample, asymptotic, and wall‑clock efficiency.
