Key Points
- A recent update to llama.cpp reportedly broke web search tool calling when using the Qwen 3.6 27B model in Open WebUI.
- The only noted change was on the backend (the llama.cpp update), suggesting an incompatibility introduced by that update.
- The reported model used is the unsloth Q4-K-XL GGUF, and users are asking for confirmation of the cause and affected configurations.
- The issue appears to be tool-calling specific rather than a general failure, indicating a regression in how tool calls are handled through the updated backend.
