Checked 2026-11-05

Qwen3.8 2.4T A95B is the open-weight version of Alibaba's Qwen3.8 Max, for teams with a serious GPU cluster who want a frontier-size model they can host. The Hugging Face card gives 2.4 trillion parameters in total with 95 billion active per token, a native context of 262,144 tokens that can stretch to 1,010,000, and an August 2026 date. It takes text only, thinking cannot be switched off, and every reply opens with a reasoning block. The card recommends recent SGLang, vLLM or TokenSpeed builds and states no memory needs. The licence is a custom Qwen3.8-Max licence, not Apache. Use is free, but a company running a model-as-a-service or coding-assistant business over $50 million in twelve months needs a separate licence, and large products must show the model name. OpenRouter lists it from 12 August 2026 at $2 per million input tokens and $6 per million output tokens on its cheapest route as listed on 5 November 2026. We have not run it ourselves. We would use the API route first and read the licence before self-hosting.
