Qwen3-Next-80B-A3B-Instruct
Support summary
Qwen3-Next-80B-A3B-Instruct is a checkpoint published by Qwen, built on the Qwen3NextForCausalLM architecture. The newest indexed releases vLLM 0.28.0 and SGLang 0.5.19 both document support. TensorRT-LLM lists its architecture, but not this exact checkpoint.
vLLM documents support in 20 of 20 indexed releases, from 0.17.0 to 0.28.0. SGLang documents support in 13 of 13 indexed releases, from 0.5.10 to 0.5.19.
