Bug Fix

Ollama v0.17.3 resolves a parsing issue that affected tool calling capabilities in Qwen 3 and Qwen 3.5 model families. The bug specifically occurred when tool calls were emitted during the model's extended thinking process, causing the calls to be parsed incorrectly and preventing proper execution.

What You Need to Know

If you're using Ollama with Qwen 3 or Qwen 3.5 models and relying on tool/function calling features, this update is recommended. The fix ensures that tool calls are correctly parsed regardless of whether they occur during normal inference or during the model's thinking phase.

Action Items

  • Update recommended: Pull the latest v0.17.3 release to restore proper tool calling functionality for Qwen models
  • No breaking changes: This is a backward-compatible patch with no API changes required
