  • How is Qwen3.8 2.4T A95B different from Qwen3.8 Max?

    Qwen3.8 2.4T A95B is the open-weight release and Qwen3.8 Max is the hosted endpoint. The open version omits some cloud features, including image input and a non-thinking mode.

  • How many parameters does Qwen3.8 2.4T A95B use per request?

    95 billion active out of 2.4 trillion total, routed across 512 experts. Only the active parameters take part in any single forward pass.

  • What is the context window for Qwen3.8 2.4T A95B?

    The context window is 262.1K tokens, with up to 131.1K tokens per response. Linear attention on most layers replaces a growing KV cache with a bounded recurrent state, which is what keeps long context servable.

  • Is Qwen3.8 2.4T A95B free to use commercially?

    The weights are open but the license is not unrestricted. Model providers earning more than 50 million US dollars in a twelve-month period must obtain a commercial license from Alibaba Cloud. Read the license before building a hosted product on it.

  • How does Qwen3.8 2.4T A95B perform on coding benchmarks?

    Unevenly. It reaches 86.6 on Terminal Bench 2.1, but DeepSWE 1.1 at 56.6 and FrontierSWE at 73.5 sit lower relative to the field. Benchmark it on your own repository before committing a coding workload.

  • Do I need my own hardware to run Qwen3.8 2.4T A95B?

    Not through AI Gateway. Self-hosting the full weights takes roughly 4.89 TB, though 4-bit quantized checkpoints reduce that substantially for NVIDIA and AMD nodes.

  • Does Qwen3.8 2.4T A95B support Zero Data Retention?

    Yes, Zero Data Retention is available for this model. Zero Data Retention is offered on a per-provider basis. See https://vercel.com/docs/ai-gateway/capabilities/zdr for details.
