Qwen AgentWorld 35B A3B
Qwen-AgentWorld-35B-A3B is an Apache-2.0 licensed text-generation language world model from the Qwen repository. It is a causal language model based on Qwen/Qwen3.5-35B-A3B-Base, trained through CPT, SFT, and RL stages for agentic environment simulation. The model predicts the next environment state given an agent's action and interaction history, covering seven agent interaction domains: MCP (tool calling), Search, Terminal, SWE, Android, Web, and OS. It has 35B total parameters with 3B activated, a context length of 262,144 tokens, and is compatible with Hugging Face Transformers, vLLM, and SGLang.

Tradeoffs
- The supplied source does not specify hardware requirements or performance benchmarks for deployment
- No information is provided about license compatibility, licensing restrictions, or commercial-use terms beyond the stated Apache-2.0 license
- The source states the model is not trained on outputs from external API services, which may limit behavior involving such services
- The supplied performance table is incomplete; no full benchmark results are available to assess real-world capabilities
- The source does not include testing claims or independent validation; no claims about actual performance or reliability are made here
