1M context

Long context is offered as separate model variants: the model ID carries a [1M] suffix, and the request format is identical to the regular model.

Supported models

The IDs with a [1M] suffix in GET /v1/models; currently kimi-k3[1M].

Enable it

Set model to the suffixed ID; no other parameters are needed:

{
  "model": "kimi-k3[1M]",
  "messages": [{"role": "user", "content": "<very long content>"}]
}
