Arctic-AWM-4B is a multi-turn tool-use agent model trained with agentic reinforcement learning on Qwen3-4B, using the fully synthetic environments from AgentWorldModel-1K.
The model is trained to interact with tool-use environments exposed via a unified MCP (Model Context Protocol) interface, enabling strong multi-turn agentic capabilities.
