Kimi K3 API and Developer Notes in motion

This short video summarizes the page: the source set, the decision boundary and the practical next action.

Kimi K3 API and Developer Notes visual summary
01

API shape and model examples

The source ledger records the official quickstart as OpenAI-compatible, with base_url set to https://api.moonshot.ai/v1 and example model kimi-k3. Kimi Code uses separate coding endpoints and model configuration.

01 · Base URL A build can start OpenAI-compatible, then branch for Kimi Code endpoints when coding tools need them.
02

Reasoning and context controls matter

The K3 API guide notes that K3 always thinks. Developers can adjust reasoning_effort across low, high and max, and can set max_completion_tokens up to 1,048,576 when a workflow needs the long context ceiling.

02 · Reasoning effort The planner below lets teams test token volume against the recorded price points.
03

Pricing must be rechecked before production

At collection time, the API platform showed cache hit $0.30/MTok, input $3.00/MTok and output $15.00/MTok. Treat those as planning defaults and verify the current platform page before billing decisions.

03 · 1M context Cost cards show separate cache, input and output meters because K3 pricing is not one flat token rate.
