Learn how to call the Kimi model inference service deployed on Alibaba Cloud Model Studio.

Important

The Moonshot-Kimi-K2-Instruct and kimi-k2-thinking models will be retired on July 9, 2026. We recommend switching to qwen3.7-plus, qwen3.7-max, or qwen3.6-flash.

Supported regions: .

To try the Kimi model, go to the model experience center.

Service endpoints vary by region. Configure the Base URL for your region.

Response

plaintext
====================Thinking Process====================
The user asks "Who are you?", which is a direct question about my identity. I need to answer truthfully based on my actual identity.

I am Kimi, an AI assistant developed by Moonshot AI. I should state this clearly and concisely.

The response should include:
1. My identity: AI assistant
2. My developer: Moonshot AI
3. My name: Kimi
4. My core capabilities: long-text processing, intelligent conversation, file processing, etc.

I should not pretend to be human or provide excessive technical details. A clear and friendly answer is sufficient.
====================Complete Response====================
I am Kimi, an AI assistant developed by Moonshot AI. My skills include long-text processing, intelligent conversation, question answering, content creation, and file analysis and processing. How can I assist you?

Multimodal call example

kimi-k2.5 and kimi-k2.6 can process text, image, and video inputs. To enable thinking mode, set the enable_thinking parameter. The following examples show how to use these multimodal capabilities.

Thinking mode

kimi-k2.5 and kimi-k2.6 are hybrid thinking models. These models can respond after thinking or respond directly. The enable_thinking parameter controls whether to enable the thinking mode:

  • true: Enables thinking mode.

  • false (default): Disables thinking mode.

kimi-k2.6 supports passing the thinking process in multi-turn conversations with the preserve_thinking parameter. For more information, see Passing the thinking process.

The following examples demonstrate how to use an image URL and enable thinking mode. The main example shows a single-image input, and the commented-out code shows a multi-image input.

Video understanding

Video file

Image list

The kimi-k2.5 and kimi-k2.6 models analyze video content by extracting a sequence of frames. You can control the frame extraction strategy by using the following two parameters:

  • fps: Controls the frame extraction frequency. One frame is extracted every fps1 seconds. The value must be in the range [0.1, 10], and the default value is 2.0.
    • For high-motion scenes: Set a higher fps value to capture more detail.

    • For static or long videos: Set a lower fps value to improve processing efficiency.

  • max_frames: Limits the maximum number of frames to extract from a video. The default and maximum values are both 2000.

If the total number of frames calculated from the fps value exceeds this limit, the system automatically extracts frames uniformly to meet the max_frames limit. This parameter is available only when you use the DashScope SDK.

When passing a video file to the model using the OpenAI SDK or an HTTP request, set the"type" parameter in the user message to"video_url".

When providing a video as an image list (pre-extracted video frames), use thefpsparameter to specify the original video's frame extraction rate. This helps the model better understand the event sequence, duration, and dynamic changes. The value of the fps parameter indicates that frames were extracted from the original video everyfps1seconds.

You can pass a local file path directly to the model. This method is supported only by the DashScope Python and Java SDKs and is not available for DashScope HTTP calls or in OpenAI-compatible mode. The table below shows the required path format for each programming language and operating system.

File limitations

Image limitations

Video limitations

  • Image resolution

    • Minimum size: Width and height must both be greater than 10 pixels.

    • Aspect ratio: The ratio of the longest side to the shortest side must not exceed 200:1.

    • Maximum resolution: For best performance, keep the image resolution at or below 8K (7680x4320). Images with higher resolutions may cause API timeouts due to large file sizes and long transmission times.

  • Supported image formats

    • For resolutions below 4K(3840x2160), the following image formats are supported:

      Image formatFile extensionMIME type
      BMP.bmpimage/bmp
      JPEG.jpe, .jpeg, .jpgimage/jpeg
      PNG.pngimage/png
      TIFF.tif, .tiffimage/tiff
      WEBP.webpimage/webp
      HEIC.heicimage/heic
    • For resolutions between 4K (3840x2160) and 8K (7680x4320), only the JPEG, JPG, and PNG formats are supported.

  • Image size

    • When you provide an image via a public URL or local path, it must not exceed 10 MB.

    • When using Base64 encoding, the encoded string must not exceed 10 MB.

To reduce the file size, see How to compress an image or video to meet the size limit.

  • Number of images The number of images you can provide is determined by the total token count. The combined tokens from all images and text must not exceed the model's maximum input.

  • As an image list: Provide a minimum of 4 and a maximum of 2,000 images.

  • As a video file:

    • Video size:
      • Public URL: The video file must not exceed 2 GB.

      • Base64 encoding: The encoded string must not exceed 10 MB.

      • Local file path: The video file must not exceed 100 MB.

    • Video duration: Must be between 2 seconds and 1 hour.
  • Video format: Supported formats include MP4, AVI, MKV, MOV, FLV, and WMV.

  • Video resolution: Although there is no strict resolution limit, we recommend 2K or lower for optimal performance. Higher resolutions increase processing time without improving the model's understanding.

  • Audio understanding: The model does not process audio tracks in video files.

Models and billing

Kimi is a series of large language models from Moonshot AI.

  • kimi-k2.6: The latest and most capable model in the Kimi series. It delivers stronger, more reliable long-horizon coding, with major gains in instruction following and self-correction. It also supports text, image, and video input; thinking and non-thinking modes; and both conversation and agent tasks.

  • kimi-k2.5: Achieves open-source SOTA on agent tasks, code generation, visual understanding, and a broad set of general intelligence tasks. It also supports text, image, and video input; thinking and non-thinking modes; and both conversation and agent tasks.

  • kimi-k2-thinking: Deep thinking mode only. Displays the reasoning process through the reasoning_content field. Excels at coding and tool calling—ideal for logical analysis, planning, or in-depth understanding.

  • Moonshot-Kimi-K2-Instruct: No deep thinking mode. Generates responses directly with lower latency—ideal for quick, direct answers.

For model context window and pricing details, see the Model Studio console.

Billing is based on input and output token counts.

In thinking mode, the chain of thought counts as output tokens.
