## Tool calling improvements ### New tool calling support The following models now support tool calling: * [DeepSeek-R1-2508](https://ollama.com/library/deepseek-r1:671b) (671B model) * [Magistral](https://ollama.com/library/magistral) Tool calling reliability has also been improved for the following models: * [Llama 4](https://ollama.com/library/llama4) * [Mistral](https://ollama.com/library/mistral) To re-download the models, use `ollama pull`. ## New Ollama for macOS and Windows preview A new version of Ollama's macOS and Windows applications are available to test for early feedback. New improvements to the apps will be introduced over the coming releases: * [Download for macOS](https://github.com/ollama/ollama/releases/download/v0.9.1/Ollama-Preview.dmg) * [Download for Windows](https://github.com/ollama/ollama/releases/download/v0.9.1/OllamaSetup-Preview.exe) If you have feedback, please create an issue on GitHub with the `app` label. These apps will automatically update themselves to future versions of Ollama, so you may have to redownload new preview versions in the future. <img width="1073" alt="Screenshot 2025-06-17 at 11 41 43 AM" src="https://github.com/user-attachments/assets/fe69e299-3d62-49c1-a16f-65b6ac426c83" /> ### New features #### Expose Ollama on the network Ollama can now be exposed on the network, allowing others to access Ollama on other devices or even over the internet. This is useful for having Ollama running on a powerful Mac, PC or Linux computer while making it accessible to less powerful devices. #### Allow local browser access Enabling this allows websites to access your local installation of Ollama. This is handy for developing browser-based applications using Ollama's [JavaScript library](https://github.com/ollama/ollama-js). #### Model directory The directory in which models are stored can now be modified! This allows models to be stored on external hard disks or alternative directories than the default. #### Smaller footprint and faster starting on macOS The macOS app is now a native application and starts much faster while requiring a much smaller installation. ## What's Changed * [Magistral](https://ollama.com/library/magistral) now supports disabling thinking mode. Note: it is also recommended to change the system prompt when doing so. * Error messages that previously showed `POST predict` will now be more informative * Improved tool calling reliability for some models * Fixed issue on Windows where `ollama run` would not start Ollama automatically ## New Contributors * @JasonHonKL made their first contribution in https://github.com/ollama/ollama/pull/10174 * @hwittenborn made their first contribution in https://github.com/ollama/ollama/pull/10998 * @krzysztofjeziorny made their first contribution in https://github.com/ollama/ollama/pull/10973 **Full Changelog**: https://github.com/ollama/ollama/compare/v0.9.0...v0.9.1
