What is Osaurus?
Native, Apple Silicon–only local LLM server. Similar to 
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, 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
