Qwen3.6-27B Gets Stuck in Claude Code Loop

A Reddit user reports that Qwen3.6-27B-FP8, served through vLLM and used in Claude Code, sometimes announces that it will continue with remaining edits and then pauses for user input instead of executing the next step. The behavior appears intermittent and can repeat even when the model claims the user already replied “continue.” The report suggests a workflow mismatch between Claude Code’s prompting/tooling contract and the model’s agent behavior, rather than an obvious vLLM failure.

// ANALYSIS

Qwen3.6-27B can get stuck in Claude Code’s “continue” loop instead of finishing the job.

–The failure mode is conversational, not infrastructural: the model is still responding, but it’s dropping into a user-turn expectation instead of advancing the tool/action loop.
–The fact that it happens in Claude Code but not OpenCode points to prompt- and host-specific behavior, not a universal model defect.
–Qwen3.6-27B’s agentic coding strengths may still require tighter system prompts or host-side guardrails to keep it from “asking permission” mid-task.
–If you are evaluating this stack, test for tool-loop continuity, not just one-shot coding quality; that is where the weakness shows up.
