View guide →Snowflake's Agent World Model: synthesise 1,000 executable MCP tool-use environments for agentic RL.
agent-world-model is an open-source ai agents project by Snowflake-Labs (Snowflake-Labs/agent-world-model on GitHub). It has 465 GitHub stars and 50 forks, is released under the NOASSERTION license, and was last updated on GitHub on 28 May 2026.
Decide whether to use the 1,000 released environments directly or synthesise your own from seed scenarios.
Clone the repository, run uv sync, and download the released environments dataset from Hugging Face if you are using them.
Set your LLM provider credentials and model choices for synthesis and verification.
Start an environment's MCP server, run the demo agent against a task, and verify its trajectory with the built-in judges.
The awm CLI generates scenarios, tasks, database schemas and sample data, API specifications, MCP environment code, and verifiers, or runs the whole pipeline at once.
The synthesised environments, tasks, databases, and verification are published on Hugging Face and can also be tried in a live demo Space.
Every environment is exposed as an MCP server, so agents interact through the same list_tools and call_tool protocol.
Start servers per scenario, health-check one or all environments, and reset databases to their initial state between runs.
Verify agent trajectories with a code-augmented LLM-as-a-judge or a purely code-based judge.
An adapted evaluation harness covers BFCLv3, tau2-bench, and MCP-Universe under the same MCP tool protocol, with trained Arctic-AWM models released alongside.
The project uses uv for its Python environment.

awm agent --task "show me the top 10 most expensive products" --mcp_url http://localhost:8001/mcp --api_url http://localhost:8000/v1 --model Snowflake/Arctic-AWM-4BIt is developed by Snowflake AI Research with UNC-Chapel Hill collaborators, under the Snowflake-Labs organisation; the README notes its infrastructure was merged into Meta PyTorch's OpenEnv.
The code and the 1,000 environments are openly released on GitHub and Hugging Face, but the catalog metadata lists no license, so check the repository's license file before relying on specific terms.
For synthesis and LLM-judge verification, yes: you configure an OpenAI or Azure OpenAI key. Using the released environments with a locally served model needs no key.
Hand-built environments like a single benchmark suite are fixed; AWM generates environments itself, so you can scale to a thousand worlds and synthesise new ones for new domains.
Clone the repo, uv sync, download Snowflake/AgentWorldModel-1K from Hugging Face, start an environment with awm env start, and run the demo agent.
