Tip: Watch for Extra Spaces in chat-template-kwargs When Running Qwen3.6 via llama-server — Breaks preserve_thinking

r/LocalLLaMA·low signal

A PSA on r/LocalLLaMA warns that extra whitespace in the chat-template-kwargs parameter silently breaks preserve_thinking when running Qwen3.6 through llama-server. The parameter parses as a string literal including the spaces, so 'preserve_thinking = true' fails while 'preserve_thinking=true' works. This is a non-obvious gotcha that can waste hours debugging, especially for developers integrating local Qwen3.6 into agentic coding pipelines where thinking/reasoning traces are critical for chain-of-thought workflows.
