Osaurus

You've been renting your AI. This is what owning it looks like. Local model. No account. No API key. Free. Open source. No Electron. github.com/osaurus-ai/osaurus

Osaurus is on Windows now. Free. Watch it close out a month of books on a PC: invoices matched, a double payment caught, workbook written. No cloud, no subscription. Native C#, no Electron. Public beta is open. Thanks to the community member who built the port. osaurus.ai/windows

Most Macs have 8 or 16GB. Model releases pretend they don't. Raptor 0.5: a local agent model built for the Macs everyone actually owns. 8B MoE, ~1B active per token, 6.3 GB, free, MIT. Reads files, checks spreadsheets, drafts emails. github.com/osaurus-ai/osaurus osaurus.ai/models/raptor-05

Solid open source harness that can create agents with just a request 👇🏻

Osaurus now has an Orchestrator. Talk to it and it configures the app, creates agents, and schedules work. Every change shows an approval card first. It plans and delegates, your agents execute. Free, open source, native macOS. github.com/osaurus-ai/osaurus

Your chats shouldn't start from zero. Projects are live in Osaurus. Related chats share one set of instructions, knowledge, and memory. Tell one agent your bench max. Ask a different agent on a different model. It knows. Free and open source: github.com/osaurus-ai/osaurus

Qwen3.8 27B, hours after the weights dropped: writing and testing its own code, fully local on a Mac. Pure Swift. No Electron. No cloud round trips. Open source: github.com/osaurus-ai/osaurus

Osaurus can now import your chat history from ChatGPT, Claude, Grok, Gemini, and Open WebUI. Export from the app, drop the file in, continue every conversation with any model. Your conversations shouldn't be locked to one app. Free and open source: github.com/osaurus-ai/osaurus

Every bot in your Slack runs on someone else's GPUs. This one runs on my Mac. Ornith 1.0 9B, open weights, answering a mention in our team channel with a tool call and a formatted table. Free and MIT licensed: github.com/osaurus-ai/osaurus

A 9B model just checked my Amazon shopping cart. Opened a real browser. Signed in. Read the page. Reported back. Running locally on a Mac. Free and open source. github.com/osaurus-ai/osaurus
