A Reddit user reports that the Qwen3.6-27B model suffers from tool-call failures and infinite loops, making it unreliable for fully local use without constant monitoring.
To address this, the user developed an extension for the Pi coding agent that monitors the JSON stream for looping behavior and checks if the user's goal has been reached. If the main model stops prematurely or goes off track, the extension automatically injects prompts to encourage the model to continue.
The author notes that this workaround allows them to safely walk away from large tasks and asks the community what other methods are being used to handle local model quirks.
