OpenAI- and Anthropic-compatible API on a Mac Studio M5 Ultra, for Claude Code, opencode and your own tools
Point your coding agent at a real Mac Studio instead of a cloud GPU. The endpoint speaks the OpenAI and the Anthropic format, so Claude Code, opencode, the official SDKs and curl work as they are.
Free: 2 chat questions and 2 minutes with your coding agent. No card needed.
- Two endpoints.
/v1/chat/completionsand/v1/messages, with streaming, tool calls and up to 64K tokens of context. - Built for agents. A prefix cache keeps long sessions fast: after the first step, follow-up steps start in about a second.
- Measure it yourself. Your dashboard shows tokens, cache hits and speed for every request, so you can judge whether local hardware is enough for your team.

FAQ
Which coding agents work?
Anything that speaks the OpenAI API (/v1/chat/completions) or the Anthropic API (/v1/messages): Claude Code, opencode, the official SDKs and plain curl. Ready-made configs are on the agent page.
How long can my prompts be?
The models support up to 256K tokens of context. For coding agents we recommend 64K – the configs on the agent page set this for you. The free chat accepts about 8,000 tokens of history.
What is included for free?
2 questions in the chat and 2 minutes with your coding agent, starting with its first request – shared across both machines. When the time is up, your agent gets one last answer: what's done and what would still be open.
Is my code stored?
We do not store chats or prompts – only counts like tokens and speed. To make follow-up requests fast, the machine keeps a cache of recently processed text on its SSD, which is overwritten automatically. Please do not send secrets.
