The native macOS harness for AI agents. Any model, persistent memory, autonomous execution, cryptographic identity. Built in Swift. Fully offline. Open source.






Hi, this is cool. What are some exciting and unique ways that people are using Osaurus and is there a roadmap?
Osaurus
Hey @andrea_j , great question!
Honestly the sandbox stuff surprises me the most. Agents spin up an isolated Linux VM and make real things: slide decks, 3D games, deployed websites. Recently I watched an agent write its own skill to solve a task, which was a little surreal.
Roadmap: personal AI you actually own. Agents, memory, skills that live on your Mac and compound over time. Lots left to build.
Curious what you'd want your Mac to do on its own!
@tpae Are the latest local models to download updated regularly? How do I know which ones work well on my machine? What's the best way to find ones that meet my needs? Thanks
Osaurus
@andrea_j great question! We add new models very frequently, we quantize them ourselves for the best experience and compatibility with the harness. We let you know which models are too big, or which models are just the right fit.
@tpae Thanks - I'm starting to play with Osaurus atm. Could I give my dino agent a set of pdf books to read and he could talk/speak to me about them as an expert on those topics? Could he then research these topics daily and build a memory? Oh, and what makes this different than LLM Studio/ Ollama?
@Osaurus Congrats on the Launch. The Osaurus dino is super cute.
I have been waiting to try locally run models and see the performance. What the hardware requirement? is a M4 Mac mini 16gb enough? Eager to try it.
Osaurus
Hey @roopesh_donde !
16gb would be usable, although 24gb would be recommended. I would suggest using Gemma 4 e4b, it's not crazy smart like the others but is able to call tools in a meaningful way. Let me know if you run into any questions!
Does it take a lot of space in my computer?
Osaurus
@doganakbulut Depends on which model you download, but it ranges between 6GB ~ 20GB for smaller models, and could be more than 200GB+ for larger ones
DiffSense
Third and final question 🙏 Does Osaurus have a cli input? Like is it possible to invoke an action via cli to it? If you know what I mean?
Osaurus
@conduit_design Osaurus does have CLI input! You can read more about it here: https://docs.osaurus.ai/cli
You can invoke actions using our MCP server.
Downloading to check this out now! Just the branding of the dinosaurs is unique enough to pique my interest, would love to know where you got the idea to use them. Make the internet fun again!

@rick_mcclelland Let's make it fun!
My son was getting into dinosaurs (he's turned 3), and I wanted to build something fun with AI. I built Dinoki (pixel dinosaur desktop AI companion), and realized there's a growing need to run local models (for costs and privacy). Dinoki will be central to what we do, so when we built Osaurus, we decided to keep the same branding.

Swift-native, fully offline, and open source is a rare combo — most agent harnesses assume you're fine piping everything to the cloud. The cryptographic identity piece is intriguing; I'd love to hear more about how persistent memory works across sessions and whether it's local-only storage. This feels built for people who actually care about owning their stack. Nice work.
Osaurus
@kelly_king3 Thank you Kelly! Memory is stored locally on device, using local embeddings. It works fully offline as well. We believe everyone should own their AI.
Finally a Swift-native agent harness that doesn't feel like a wrapper around a Python script. The persistent memory across sessions actually held context from yesterday, which surprised me.
Osaurus
Hey@hargdeansa20796 I'm tired of wrappers too. Mac users deserve something better. Which is why we built Osaurus.
Let us know if there's any feedback or suggestions on how to make it better.
