From v0.40.0, Ollama automatically runs model architectures that its MLX engine supports on Apple Silicon Macs, with no change to `ollama run`. The release names Qwen3.8, Gemma 4, Qwen3.6 and Qwen3.5 among the covered models, and adds MLX versions of its decision models and of the EmbeddingGemma 2 embedding model. Ollama says it will keep testing and enabling more models.

## Why it matters locally

Mac users get Apple's own machine-learning framework under the hood without new commands, while models outside the MLX list keep running as before; if a model behaves differently after updating, check this switch first.
