Model Card
Kimi V1 32K Vision Preview is a multimodal chat model from Moonshot AI, the Beijing company behind the Kimi assistant. The kimi-v1 model ID refers to the same V1 line that Moonshot's Kimi platform also lists as moonshot-v1; this route serves the 32K vision preview tier of that family.
The vision preview accepts image input alongside text and can read text in images, identify colors, and describe object shapes, which covers screenshot interpretation, chart reading, and lightweight document OCR. Images are billed as tokens based on resolution, and Moonshot notes that resolutions above 4K add cost without improving understanding.
The 32K context tier sits between the 8K and 128K variants, fitting multi-turn conversations and medium-length documents that mix visuals with text. The API is OpenAI-compatible and supports streaming and tool calling.

Kimi K3.1 Pro
Kimi K3.1 Pro is a multimodal language model from Moonshot AI, announced October 23, 2026 as a post-trained upgrade of Kimi K3. It accepts text, image, and video input, has a 1-million-token context window, and Moonshot plans to release the weights by November 4. Moonshot reports 65.7% on Terminal-Bench 4.0, ahead of GPT-6 Astra and slightly behind Claude Opus 5.5, and 92.7% on BenchCAD, a 3D model coding benchmark. It also reports higher scores than both models on OfficeQA Pro v2, a financial analysis benchmark. Cybersecurity benchmark scores trail both, since Moonshot removed cybersecurity content from post-training data. It suits developers building coding agents, tool-calling pipelines, and financial or document analysis workflows that need long context and multimodal input.
ChatKimi K3.1 Pro HighSpeed
Kimi K3.1 Pro HighSpeed is the faster-serving variant of Kimi K3.1 Pro, the multimodal language model from Moonshot AI announced in October 2026. It accepts text, image, and video input and has a 1-million-token context window. Moonshot says it delivers the same model capabilities as Kimi K3.1 Pro at 2 to 3 times the output speed, for more responsive interactions. It is priced at twice the standard model's rate. Choose it when latency matters more than cost, such as interactive coding agents, tool-calling loops with many sequential steps, and chat or document analysis features where users wait on the response. For batch or background jobs, the standard Kimi K3.1 Pro costs less.
ChatKimi K3
Kimi K3 is Moonshot AI's flagship open-weight model, released July 16, 2026, with full weights following on July 27. At roughly 2.8 trillion parameters in a Mixture-of-Experts architecture, Moonshot positions it as the largest open-source model released to date, built on two new components: Kimi Delta Attention, a hybrid linear attention mechanism, and Attention Residuals, a replacement for standard residual connections. It runs in an always-on thinking mode with a 1-million-token context window and accepts text, image, and video input. Reported results include 93.5% on GPQA Diamond, 91.2% on BrowseComp, 88.3% on Terminal-Bench 2.1, and a first-place finish on Arena.ai's Frontend Code Arena, putting it close to Claude Opus 4.8 and GPT-5.5 on several agentic and coding tasks. These figures come from Moonshot and early testers, not independently confirmed leaderboards. It suits developers building long-horizon coding agents and tool-calling pipelines who want frontier-level performance at open-weight pricing.
