TechCrunch·medium signal

Osaurus, covered by TechCrunch on May 15, is an open-source macOS AI runtime that runs local MLX models and cloud APIs through a single interface with MCP tool sharing and drop-in OpenAI/Anthropic compatibility. It supports MiniMax M2.5, Gemma 4, Qwen3.6, GPT-OSS, Llama, DeepSeek V4, and Apple's on-device foundation models, all running in a hardware-isolated virtual sandbox. The 64GB RAM requirement for local models reflects the growing 'own your AI' movement where developers want provider-independent infrastructure on Apple Silicon.
