Journalists can't upload a leak to the cloud. So we turned off the Wi-Fi. A 1.7B model read the whole case file, followed the money, and cited its sources. LFM3. Day 0 on Osaurus.

You've been renting your AI. This is what owning it looks like. Local model. No account. No key. Free. Open source. No Electron.

We shrank a frontier model to 102GB. DeepSeek V4 Flash 0731 now runs on a 128GB Mac. One prompt, it wrote Minesweeper, checked its own code with Node, shipped a working game. Free on Osaurus.

This is what native feels like. No Electron. No Python runtime. Just Swift on Apple Silicon.

This is a 9B model running a full agentic loop with Wi-Fi off. Ornith 1.5. It read three sheets, cross-referenced the monthly rollups, and wrote a revenue analysis on its own. Nothing left the Mac.

Most Macs have 8 or 16GB. Model releases pretend they don't. About 40% of Osaurus users are on those machines. So we built them an agent model. It reads your files, checks your spreadsheets, drafts your emails. Raptor 0.5. 8B MoE. ~1B active per token. 6.3 GB. Resident all day. Free.

Congrats to the Ornith team. Ornith-1.5-122B is a monster. It’s in Osaurus on day one. Running on a Mac, no cloud, no subscription. One prompt. It built a flying car game.

Claude Code just booked me a flight to Japan. Opened Safari. Searched Google Flights. Selected the cheapest option. Got to checkout. I just watched.

No Electron. No CLI. No Python. No vision model. Just native Swift reading the accessibility tree and driving your real apps. Free. MIT licensed.

Bonsai 2 dropped hours ago. It's already doing real work in Osaurus. Read two CSVs. Wrote the Python. Drew the chart. Then found the one channel losing money and told me why. 27B. Ternary. Nothing left the Mac.

This is what "Personal Computer" should mean. Fully offline. Any model. Isolated sandbox. No subscription. Open source.

Qwen 3.6. 35B. Running locally. 0.25s TTFT. 70 tok/s.

Raptor 0.6 just shipped. Most Macs have 8 or 16 GB. Most AI models pretend they don't. Raptor is our agent model built for those machines. Reads folders, checks spreadsheets, drafts emails. Local, free. 3.7 GB, down 41% from the last version.

AppleScript is the oldest way to drive a Mac. Frontier models butcher it. So we trained two small ones that don't. Open weights. On-device. 100% compile.

Gemini on your Mac. Native. No Electron. Google Gemini never built one — so I did.

We didn't just make local models faster. We made them dependable at tool calling. Gemma 4 12B now picks the right tool and runs it correctly, on-device and ~60% faster. Small models just got serious.

Already running on your Mac. Offline. With tools.

"Tell me about the sales actuals." It opened the folder, read the spreadsheet, and broke down Q1 revenue by region. A 2.6B model. 2.3 GB on disk. Running in Osaurus, day one.

It's here. The first fully native agent harness, built for Windows. No electron in sight. Osaurus for Windows is almost ready for beta. Get ready for a team of agents running right on your PC, local and private. Watch Qwen3.8-27B set up a team of agents to perform a code review.

Already running on your Mac. Native. No browser.
