# Qwen AgentWorld Explained: Predict Before Agents Act

**Source:** https://binaryverseai.com/qwen-agentworld-language-world-model/

## Key Takeaways

1. **Qwen AgentWorld is a LANGUAGE WORLD MODEL, not a chatbot.** It predicts the next environment state after an agent action. Normal LLM asks "What should I say or do?" → Qwen AgentWorld asks "If the agent does that, what will the world return?"

2. **Open weights available:** `Qwen-AgentWorld-35B-A3B` (open weights). Research model: `Qwen-AgentWorld-397B-A17B`.

3. **7 domains:** MCP, Search, Terminal, SWE (Software Engineering), Web, OS, Android.

4. **Training pipeline:** "CPT injects, SFT activates, RL sharpens"
   - **Continual Pre-Training (CPT):** Injects environment knowledge into the model
   - **Supervised Fine-Tuning (SFT):** Activates next-state prediction capability
   - **Reinforcement Learning (RL):** Sharpens simulation fidelity

5. **10M+ real environment interaction trajectories** used in training.

6. **AgentWorldBench scores (Overall):**

   | Model | Overall Score |
   |-------|-------------|
   | Qwen-AgentWorld-397B-A17B | 58.71 |
   | GPT-5.4 | 58.25 |
   | Claude Opus 4.8 | 56.59 |
   | Claude Sonnet 4.6 | 56.04 |
   | Qwen-AgentWorld-35B-A3B | 56.39 |
   | Qwen3.5-35B-A3B | 47.73 |

7. **GUI domains (Web, OS, Android)** use structured text representations (accessibility trees, HTML, XML), NOT raw pixels.

8. **Core loop:** interaction history → agent action → model predicts next observation → use prediction for evaluation, planning, or RL training.
