gptoss-mlx

Experimental MLX-backed Ollama build of GPT-OSS 20B.

This model requires a custom Ollama build with experimental MLX safetensors support and GptOssForCausalLM support. It will not run on the regular public Ollama app/build.

Tags

  • pd95/gptoss-mlx:20b - recommended default, currently MXFP4
  • pd95/gptoss-mlx:20b-mxfp4 - explicit MXFP4 artifact
