Sai API launches: a cloud computer for AI agents
Simular released the Sai API, which connects to Claude Code, Codex and Cursor with one command and lets agents operate a Windows VM, reaching a 79.38% partial success rate on OSWorld 2.0.
Four screenshots, the whole Sai API launch: → one line in the terminal, claude mcp add sai, and the server answers "cloud computer ready" → one prompt in Claude Code asking for a Muse-style agent app → that app running with a live view of its own Windows machine, already on a Product Hunt sign-in → "Give your agent a computer" The interesting part is what's missing. No VM image to build. No screen streaming to wire up. No click layer, no retry glue, no babysitting a browser session at 3am. That used to be the first month of every computer-use project, and most of them died right there. As a fan of open models I also like that it's model-agnostic: Claude, GPT, DeepSeek or Qwen can do the thinking while Sai operates the machine. Sai is #1 on OSWorld 2.0 in partial success rate (79.38%), which is the number people will quote. The missing infra is the part that changes what gets built. Works with Claude Code, Codex and Cursor. http://platform.simular.ai
