vLLM users hit Qwen 3.5 version friction
A Reddit post in r/LocalLLaMA asks whether anyone can successfully serve new Qwen 3.5 models on vLLM, citing dependency conflicts between vLLM and Transformers versions. The thread reflects early adopter pain around model-support timing and package compatibility rather than a formal product release.
// ANALYSIS
This is classic open-model ecosystem lag: model drops fast, serving stacks catch up unevenly.
- –The post is a developer support signal, not an official announcement from vLLM or Qwen.
- –The core issue is dependency alignment, especially Transformers compatibility with newly introduced model architectures.
- –Similar recent community threads suggest this is a recurring rollout problem for Qwen 3.5 serving workflows.
- –Practical impact is highest for self-hosters and infra teams trying to deploy new Qwen variants quickly.
