Kimi K3.1 Pro Highspeed - access through LLMTR
Kimi K3.1 Pro Highspeed is the variant of Kimi K3.1 Pro that generates its answer faster, for interactive work where waiting time matters. Its input and output token prices are twice those of K3.1 Pro; cached input costs the same. It supports a 1,048,576-token context window, image and video input (base64 data URLs only), tool calling, JSON and strict JSON Schema output. It reasons on every request and those tokens bill as output; reasoning cannot be turned off, the `low`, `high` and `max` levels can be chosen, and `max` is used when no level is sent. `temperature` and `top_p` are fixed; use `auto`, `none` or `required` for `tool_choice`. The 1-hour cache TTL cannot be requested and web search is not available on this model.
