What can you build with Kimi APIs on LinkModel?

Use live Kimi models for long-document analysis, software engineering, multimodal reasoning, research, and agentic knowledge work from one account.

Long-document and knowledge analysis

Analyze large document sets, research material, and knowledge repositories with a model selected for long-context reasoning.

Software engineering agents

Build coding assistants and multi-step engineering workflows that reason over code, call tools, and produce implementation artifacts.

Multimodal research workflows

Combine text and supported visual inputs for research, review, and knowledge-work tasks after confirming the exact live request schema.

Why run Moonshot models through LinkModel?

Access supported Kimi models alongside other language providers while centralizing credentials, usage, and pay-as-you-go billing.

One key for live Kimi models

Use one LinkModel API key for supported Moonshot models and future versions as they enter the live catalog.

Compare providers in one catalog

Evaluate Kimi alongside DeepSeek, Claude, GPT, Gemini, GLM, and other live language families without maintaining another provider billing flow.

Centralized usage and billing

Track requests and pay-as-you-go charges from one account while keeping the selected model explicit in each integration.

Integrate the Kimi API

Use one LinkModel credential to call an available Kimi model and keep model access, usage, and billing in the same workflow.

  1. Authenticate with one API key

    Create a LinkModel API key and use it to authenticate requests for Kimi models enabled for your account.

  2. Choose the live Kimi model

    Select Kimi K3 or K2.6 according to the workload, then open its model page to confirm the current identifier, price, context limit, and request schema.

  3. Send and monitor the request

    Submit your prompt or supported multimodal input, handle the response, and monitor usage from the same LinkModel account.
