The native macOS harness for AI agents. Any model, persistent memory, autonomous execution, cryptographic identity. Built in Swift. Fully offline. Open source.
You describe Osaurus as an AI agent platform rather than just an assistant. Long term, do you envision users interacting with a single persistent agent that accumulates years of context, or a collection of specialized agents with separate memory and identities?
Osaurus
@tarqiya_forgah There's use cases for both, having a single agent (or orchestrator) that accumulate years of context, and having multiple agents (or subagents) that are specialized with contexts that can perform specialized tasks.
What we're discovering now is, local models trained with specific set of tasks, they are capable of performing at the same level (if not better) than frontier models for those tasks.
We believe this is just the beginning of a local-first AI harness. We call it a platform because we expect others to join us in shaping what this future would look like.
honestly this looks great for mac users, the offline angle is a big plus. one thing i'd love to see is a simple visual diff or timeline for what the agent changed locally, like a little activity log you can scrub through. would make it way easier to trust what it's doing in the background
Osaurus
@doyranl58403 That's a great suggestion! If you are using sandbox to edit files, it does keep an internal log of changes. You can ask the agent to undo a file operation, and it will do it. We just need to make it stand out visually
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!
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.
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.
the fully-offline bit is the whole selling point for me tbh... most agent tools are just api wrappers that fall over the second the wifi does. running local on the mac with persistent memory is an actual edge, not a checkbox... swift instead of yet another electron thing is a nice touch too.
Osaurus
@alex_watson2110 Exactly. Electron is purely for companies to expand their reach, for Mac users, we're getting the shorter end of the stick. Mac users deserve better. That's why we built it in Swift.
