vLLM makes Qwen3.8-Flash-Next deployable with 262K context
You can now serve Qwen3.8-Flash-Next through vLLM, but its 262,144-token context still needs serious memory planning. The 125B-parameter model activates 6B parameters per token, while a separate 51B N-gram embedding table can be offloaded to host memory; the official recipe requires at least 51GB for that table plus runtime headroom. Use vLLM's dedicated Docker image, since PyPI installation is not supported.
