Small. Fast. Never leaves your machine.
Raptor is our own model, fine-tuned to work efficiently on Osaurus, and small enough to live on the Mac you already own. It does all its thinking on your laptop instead of in someone else's data center.
Helpers that work under your rules.
Raptor and other local models, right on your computer, no internet needed. Nothing leaves unless you choose a cloud model.
Give a Helper a folder of notes, documents or references, and it works from your own material.
Helpers build memory from your conversations and keep it on your computer.
The Privacy Filter spots things like names and account numbers, and lets you remove them before anything is sent online.
File changes need your approval, stay inside the folder you chose, and can be undone.
Insights logs everything Osaurus did, including anything that left your computer.

When I teach builders how to keep agent memory and tools on their own machine, I point them at Osaurus first.
It is a native Mac harness for AI agents. You pick a local model or a cloud one, and the memory, tools, sandbox, and identity stay on your Mac. Agents can remember what matters, run code in a sandbox, and speak OpenAI, Anthropic, and Ollama APIs on one local port so the SDKs you already use keep working. MCP works in and out, which matters when I wire Cursor into the same tool surface.
github.com/osaurus-ai/osaurus (opens in a new tab)@OsaurusAI is so damn good right now that if they ever add a feature for building apps, a LOT of apps are going to be in trouble. 😂
Seriously, Osaurus is absolutely on fire right now. 🔥A lot of time passed from the first time I tried Osaurus on my Macs. It has improved like crazy! Lot of skills, tools and more polished UI.
What a pleasant surprise! Great job @OsaurusAI 🙌And the most exciting part...
