Ollama – v0.20.6-rc0: gemma4: update renderer to match new jinja template (#15490)
New update for the Ollama crew! 🛠️
If you’ve been running Google’s Gemma 4 models locally, there is a fresh release candidate (v0.20.6-rc0) ready for testing. This update focuses heavily on keeping Ollama in perfect sync with the latest changes from Google to ensure your local inference stays rock solid.
What’s new in this release:
- Gemma 4 Template Parity: The renderer has been updated to match Google’s new Jinja template. This ensures that how your prompts are structured matches exactly what the model expects, preventing weird formatting issues.
- Parser Adjustments: Since the upstream parsing logic changed slightly, the Ollama parser has been tweaked to maintain compatibility and prevent broken inputs during model interaction.
- Improved Type Handling for Tool-Calling:
- Added special handling for simple `AnyOf` structures by treating them as type unions.
- Fixed edge cases specifically around type unions to make tool-calling much more robust and reliable.
- Better Tool Result Logic:
- The parser now prefers “empty” over “None” for certain results, which is crucial for handling legitimate empty tool calls correctly without crashing the logic.
- Added extra care when processing tool results that might have missing IDs to prevent errors in complex workflows.
It’s a great update for anyone doing heavy lifting with tool-calling and complex prompt engineering on Gemma 4! 🚀
