What is Osaurus?

Native, Apple Silicon–only local LLM server. Similar to Ollama icon Ollama, but built on Apple's MLX for maximum performance on M-series chips. SwiftUI app + SwiftNIO server with OpenAI-compatible endpoints.

Created by Dinoki icon Dinoki, a fully native desktop AI assistant and companion.

Highlights:

  • Native MLX runtime: Optimized for Apple Silicon using MLX/MLXLLM
  • Apple Silicon only: Designed and tested for M-series Macs
  • OpenAI API compatible: /v1/models and /v1/chat/completions (stream and non-stream)
  • Function/Tool calling: OpenAI-style tools + tool_choice, with tool_calls parsing and streaming deltas
  • Chat templates: Uses model-provided Jinja chat_template with BOS/EOS, with smart fallback
  • Session reuse (KV cache): Faster multi-turn chats via session_id
  • Fast token streaming: Server-Sent Events for low-latency output
  • Model manager UI: Browse, download, and manage MLX models from mlx-community
  • System resource monitor: Real-time CPU and RAM usage visualization
  • Self-contained: SwiftUI app with an embedded SwiftNIO HTTP server
