Qwen3.8 2.4T-A95B
qwenqwen/qwen3.8-2.4t-a95b
How TheRouter serves this differently from the vendor
As the vendor operates it
Alibaba publishes Qwen3.8-2.4T-A95B as an Apache 2.0 open-weight checkpoint and also lists a DashScope model ID with Qwen3.8 family serving behavior.
On TheRouter
TheRouter serves qwen/qwen3.8-2.4t-a95b as a text-only OpenAI-compatible chat model. Catalog price, context, output cap, and request parameters come from standard-models.yaml rather than the open-weight model cards.
API guide
Chat completion
Use the standard OpenAI-compatible chat route with TheRouter's public model id for text-only requests.

TheRouter catalog lists tools and tool_choice for this text route. Keep tool schemas small enough for the 1M context budget you actually want to reserve for user content.
