Use GPT-OSS for Mac Mini with Macfleet Cloud

GPT-OSS is OpenAI's series of open-weight language models designed for powerful reasoning, agentic tasks, and versatile developer use cases. With Apache 2.0 licensing, these models offer production-ready AI capabilities that run entirely on your hardware.

Key Features

• Two Model Variants: GPT-OSS-120B (117B parameters) for production use and GPT-OSS-20B (21B parameters) for lower latency
• Apache 2.0 License: Build freely without copyleft restrictions or patent risk
• Configurable Reasoning: Easily adjust reasoning effort (low, medium, high) based on your needs
• Full Chain-of-Thought: Complete access to the model's reasoning process for debugging and trust
• Agentic Capabilities: Native function calling, web browsing, Python code execution, and Structured Outputs
• Native MXFP4 Quantization: Optimized to run GPT-OSS-120B on a single H100 GPU

Getting Started

1. Install Ollama on your Mac Mini
2. Pull the model: ollama pull gpt-oss:20b or ollama pull gpt-oss:120b
3. Start using: ollama run gpt-oss:20b

Alternative installation via Hugging Face:

huggingface-cli download openai/gpt-oss-20b --include "original/*" --local-dir gpt-oss-20b/
