MoonshotAI: Kimi K3 (batch)

Kimi K3 (batch) is a MoonshotAI model that accepts text, image, and video inputs, which makes it usable for mixed-media workloads. It offers a context window of 1,048,576 tokens and caps completions at 16,384 tokens, so it can take in very large documents or long transcripts while returning moderately sized outputs. It supports tool use and reasoning. Structured output support is not specified, and its weights are not listed as open. Priced at $2.28 per million input tokens and $11.4 per million output tokens, it suits teams whose jobs involve heavy input and comparatively light output, such as analyzing long files or video. Its blended benchmark score of 73.0 rests on a single independent benchmark, with an AI index score of 71.9. That limited coverage means its standing is not well established. Buyers should test it on their own tasks before committing.
