📖 Overview

The Agent0 Series explores a new direction for autonomous agent development, showing that capable agents can improve and evolve without relying on human-curated datasets or handcrafted supervision. This repository brings together two complementary studies that advance self-improving agents through tool-integrated reasoning.

🤖 Agent0: Self-Evolving Language Agents

Unleashing Self-Evolving Agents from Zero Data via Tool-Integrated Reasoning

A fully autonomous framework that evolves high-performing language agents through multi-step co-evolution and seamless tool integration. Agent0 establishes a symbiotic competition between two agents:

• Curriculum Agent: Proposes increasingly challenging frontier tasks
• Executor Agent: Learns to solve them using external tools

Key Results:

• ✅ +18% improvement on mathematical reasoning benchmarks
• ✅ +24% improvement on general reasoning benchmarks
• ✅ Zero external data required for training
• ✅ Multi-turn interaction support

👁️ Agent0-VL: Self-Evolving Vision-Language Agents

Exploring Self-Evolving Agent for Tool-Integrated Vision-Language Reasoning

A self-evolving vision-language agent that extends the Agent0 paradigm to multimodal reasoning tasks. Agent0-VL incorporates tool usage not only into reasoning but also into self-evaluation and self-repair through a dual-role architecture:

• Solver: Performs multi-turn tool-integrated reasoning
• Verifier: Generates structured feedback and fine-grained self-rewards

Key Results:

• ✅ +12.5% average improvement on visual reasoning benchmarks
• ✅ +7.3% improvement in test-time scaling performance
• ✅ State-of-the-art among open-source vision-language models
• ✅ Zero external reward for self-evolution

🎯 Key Features

Shared Philosophy

Both Agent0 and Agent0-VL are built on the principle of zero-data self-evolution:

• No Human Annotations: Completely eliminates dependency on external data or human supervision
• Tool-Integrated Reasoning: Leverages external tools to enhance problem-solving capabilities
• Autonomous Evolution: Self-generates training data through intelligent exploration
