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.

Freshness 58 out of 100. Repository age: 140 days old, Jun 22, 2026. Measures age, not quality.
Popularity 57 out of 100. 10,200 downloads in 30 days; 746 lifetime likes. Checked Nov 8, 2026. Measures adoption, not quality.
What do these scores mean?

Two ways to compare models. Neither score measures answer quality, benchmark performance, or whether a model fits your machine.

Freshness · release age

A new release starts at 100. The score halves every 180 days: 100 × 2^(−age in days / 180). When the release date is unavailable, a repository date is a fallback—not proof of when the model was released. Missing dates stay unscored.

Popularity · adoption

Downloads over the past 30 days carry 80% of the score; lifetime likes carry 20%. Both use a logarithmic scale, capped at 10 million downloads and 100,000 likes. If likes are unavailable, downloads carry all the weight. Missing download statistics stay unscored.

round(80 × min(1, log10(1 + downloads) / 7) + 20 × min(1, log10(1 + likes) / 5))

Best for

  • Simulating agentic environments by predicting next environment states from agent actions and interaction history
  • Serving as a language world model for MCP tool-calling environments
  • Simulating Search, Terminal, SWE, Android, Web, and OS interaction domains
  • Supporting zero-shot generalization experiments in out-of-domain environments
  • Acting as a warm-up foundation for multi-turn, tool-calling agentic tasks

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
