MARTI is an open-source framework for training LLM-based Multi-Agent Systems (MAS) with Reinforcement Learning (RL). It enables powerful, scalable, and adaptive workflows by combining centralized multi-agent interactions with distributed policy training. MARTI supports both built-in graph-based workflows and popular third-party multi-agent frameworks.

MARTI-v2 extends the framework with tree search-augmented RL for complex reasoning tasks like code generation. By integrating multi-agent tree search, MARTI-v2 enables efficient multi-turn exploration with adaptive node expansion and refinement, allowing agents…
