Start with MLX. PR seventeen-oh-two-two wires up MLX unit tests directly into PR runs, downloading matching Darwin release payloads so tests can exercise MLX without a full rebuild, and pinning those tests to a single worker to keep thread-local state stable. That lands alongside PR eighteen-oh-eighty, a version…
In the same vein, PR eighteen-one-sixty bumps llama.cpp to b10729, and required regenerating the compat hooks patch because upstream restructured how tensor data gets loaded during quantization. The fix adds a caching path for text tensor reads. This is maintenance work, but it's the kind that keeps Ollama…
Second theme: correctness of model behavior. PR sixteen-four-seven-one fixes a real precedence bug — sampler defaults baked into a model's GGUF metadata or Hugging Face config were being silently overridden by Ollama's built-in defaults, unless a user explicitly set them.
