9 properties · 2 required · 8 $defs
propertytypedescriptionconstraints
messages*NIMLLMChatCompletionMessage[]A list of messages comprising the conversation so far.items ≥ 1
model*stringThe model to use.default: "moonshotai/kimi-k3"
toolsChatCompletionTool[]Optional OpenAI-compatible tool definitions for function calling.nullable
max_tokensintegerThe maximum number of tokens that can be generated.1 ≤ n ≤ 65536 · nullable
seedintegerChanging the seed will produce a different response with similar characteristics. Fixing the seed will reproduce the same results if all other parameters are also kept constant.-9007199254740991 ≤ n ≤ 9007199254740991 · nullable
streambooleanIf set, partial message deltas will be sent, like in ChatGPT. Tokens will be sent as data-only [server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events#Event_stream_format) as they become available, with the stream terminated by a `data: [DONE]`nullable
stream_optionsobjectOptional OpenAI-compatible stream options, such as `include_usage`.nullable
temperaturenumberWhat sampling temperature to use, between 0 and 1. Higher values make the output more random; lower values make it more focused and deterministic. Recommended for Kimi-K3: 1.0. Note: the other sampling parameters (top_p, presence_penalty, frequency_penalty, n) are fixed by the model and are not exposed.0 ≤ n ≤ 1 · nullable
reasoning_effortenumControls how long the model reasons before answering: `low`, `high`, or `max`. Per-request override of the serve-time default; unset falls back to the model default (`max`).low | high | max · default: "max"
