Full pricing →02How it runs
A private endpoint, not a shared API.
Launching Kimi K3 runs the model on your own instance and gives you a private, OpenAI-compatible /v1 endpoint and API key. Point any OpenAI-compatible SDK at your base URL, change the model name, and existing code works. The endpoint is yours alone — terminate the instance and it goes away with it.
Billing is by the second on the 8× 288 GB shape the launcher enforces, from boot to terminate. No commitment and no tier gates.
Limited GPU supply
8× 288 GB (B300) is the only shape with enough total VRAM for this model, and it is the scarcest node on the market — often zero available. If the launch flow shows no compute, check back later.
