Kimi AI

Kimi is an AI assistant developed by Moonshot AI, designed for conversation, research, reasoning, content creation, coding, and agent-based task execution. It combines AI chat with built-in web search, multimodal understanding, long-context processing, and autonomous agents. Kimi can work with documents and other files, conduct research, generate presentations and spreadsheets, build websites, write and analyze content, and assist with software development.

A major part of Kimi’s current platform is its AI Agent capability. Rather than only responding to individual prompts, Kimi can plan and execute multi-step tasks. Its General Agent can work on website creation, document generation, spreadsheet processing, presentation creation, and Deep Research. Kimi also offers Agent Swarm, which can coordinate large numbers of sub-agents for tasks such as large-scale searching, long-form writing, and batch processing.

Kimi provides several AI models, including K2.6, K3, and K3 Swarm. K3 is currently described by Kimi as its most powerful model, with native vision capabilities and a context window of up to 1 million tokens. K2.6 supports text, image, and video input and can be used for conversation, coding, visual understanding, and agent tasks.

Research is another core capability. Kimi includes Deep Research, which can produce detailed reports with citations and supporting information. Its agentic search capabilities can search the web as part of completing tasks, while its long-context capabilities allow it to process substantial amounts of information. Kimi supports common file formats including PDF, Word, Excel, PowerPoint, images, TXT, and video files, with files up to 100 MB and up to 50 files per session according to its current help documentation.

Kimi also provides dedicated tools for professional knowledge work. Kimi Docs can generate, convert, and review documents; Kimi Sheets can create spreadsheets with formulas, pivot tables, and charts; and Kimi Slides can turn text, documents, images, or templates into editable presentations. Kimi Websites can generate and deploy full-stack websites from natural-language instructions, design mockups, screenshots, or screen recordings, including frontend, backend, database, authentication, and deployment capabilities.

For developers, Kimi Code provides a coding-focused AI environment that includes CLI and IDE-related capabilities. Developers can also access the Kimi Open Platform API, which provides model capabilities for text generation, multi-turn conversations, file parsing, web search, and multimodal applications. The API uses an OpenAI-compatible format, making it easier for developers familiar with that interface to integrate Kimi into applications.

Kimi has an extensive plugin ecosystem for connecting external services. Officially listed plugins include Notion, GitHub, Supabase, Neon, Cloudflare, Canva, Stripe, S&P Global Market Intelligence, World Bank Open Data, IMF databases, and other financial, productivity, development, and creative services. Plugin availability can vary by region, product surface, and account type.

Kimi also supports memory, scheduled tasks, projects, Skills, voice calls, translation, image generation, video generation, and audio generation through supported plugins. Its multilingual capabilities cover both the interface and AI conversations, with official documentation currently listing English, German, Russian, French, Traditional Chinese, Korean, Portuguese, Thai, Turkish, Spanish, Italian, Indonesian, and Vietnamese.

Kimi uses a combination of free access, paid memberships, API usage, and business offerings. The current membership structure includes Moderato ($19/month), Allegretto ($39/month), Allegro ($99/month), and Vivace ($199/month), with annual billing available at lower effective monthly prices. Kimi also states that K2.6 is free in Chat and does not consume membership credits, while higher-level agent features and other services use a shared credit pool.

Overall, Kimi is positioned as a broad AI assistant and agent platform combining conversational AI, deep research, coding, document and spreadsheet automation, presentation creation, website development, multimodal processing, and third-party integrations. Its strongest differentiators are its long-context capabilities, agentic workflows, research tools, professional productivity features, and growing plugin ecosystem.
