# Moonshot launches Kimi K3.1 Pro on the Kimi API platform with a quickstart for kimi-k3.1-pro and kimi-k3.1-pro-highspeed

## Retrieval answer

Moonshot has documented Kimi K3.1 Pro on its Kimi API platform.

Moonshot has documented Kimi K3.1 Pro on its Kimi API platform. The quickstart lists two model IDs: `kimi-k3.1-pro` and `kimi-k3.1-pro-highspeed`, the latter described as delivering two to three times the speed of the base Pro model.

The documentation specifies a one-million-token context window, vision input, tool calling, and streaming responses with reasoning content separated from the main content. Thinking is always enabled. A top-level `reasoning_effort` parameter accepts `low`, `high`, or `max`, with `max` as the default.

API access is unlocked after a successful top-up of at least $1. Cumulative top-ups determine the account tier and rate limits. Moonshot describes K3.1 Pro as a post-trained Kimi K3 model and says full weights will be released by November 4.

The source does not provide API token pricing, current rate-limit figures, a release year for the weights date, or independently verified benchmark results. Several benchmark values displayed in the documentation excerpt are placeholders.
