Qwen2.5-Max: Exploring the Intelligence of Large-scale MoE Model

Qwen's Qwen2.5-Max announcement described a model trained first on more than 20 trillion text units, then refined with curated examples and feedback-based rewards. The distinction matters: exposure to a large training corpus was followed by training intended to shape how the model responds to requests. The January 2025 release reported separate evaluations of the base and instruction-tuned models.

The announced access was through chat and a developer API. For builders, this offered a way to integrate the hosted model into applications. The article did not provide downloadable weights or a parameter count, so it did not establish a self-hosting option or the hardware that would require.

“Many critical details regarding this scaling process were only disclosed with the recent release of DeepSeek V3.”
