Kimi K3 - access through LLMTR
Moonshot AI Kimi K3 is the current flagship Kimi model for long-context analysis, multi-step agent workflows and visual understanding. It supports a 1,048,576-token context window, image input (base64 data URLs), function calling, JSON output and automatic prompt caching. Thinking is on by default and can be turned off with reasoning:false in the request body or the :fast model suffix. Sampling parameters are fixed (temperature=1, top_p=0.95); tool_choice accepts auto, none or required. Web search is not supported on this model. Pricing is $0.30/1M cached input, $3.00/1M cache-miss input and $15.00/1M output. Reasoning tokens are billed as output; keep max_tokens generous even for short answers.

- LLMTR provider for the Pi coding agent and its generated catalog - Pi registers a provider through a small factory function and leaves the model list to a generation script rather than maintaining it by hand. This guide explains how those two files relate and what the request body contains.
