Kimi
Readers, researchers, and coders often keep this one pinned. Kimi broke out on ultra-long context; now it runs agents, builds slides, and ships sites—basic chat is free, advanced workflows need a membership.

Site Introduction
Kimi AI is an agentic AI assistant launched by Moonshot AI. In 2026, its flagship model Kimi K3 has been released, focusing on programming and knowledge work.
Unlike ordinary chatbots, Kimi can plan tasks on its own, process batches, and generate long documents. It is available on web, app, and desktop, with a single account synced across all platforms.
Core Features
1. Multi-Model AI Chat
Offers three tiers of models: K2.6, K3, and K3 Cluster. K2.6 responds quickly and is suitable for everyday Q&A. K3 has the strongest overall capability and can generate editable .pptx, .docx, and .xlsx files. K3 Cluster supports thousands of parallel tool calls, making it ideal for large-scale search and batch tasks. The K3 context window can reach up to 1 million tokens.
2. Agent Capabilities
The sidebar integrates a full set of Agent capabilities: Deep Research, Documents, PPT, Website, Spreadsheets, Design, plus plugins and scheduled tasks. Give it a complex request and it will break it down, execute, and deliver the result on its own—no need for step-by-step instructions.
3. Kimi Code Programming Assistant
An AI programming tool for developers, supporting CLI, VS Code, and third-party tool integration. It runs on Kimi K3 under the hood, with strengths in long-range programming and code reasoning. Members share the same quota pool, with a separate rate limit of 5 hours per week.
4. Kimi Work and Kimi Claw
Kimi Work is a local desktop Agent that performs file operations and scheduled tasks on-device. Kimi Claw is a cloud-deployed personal Agent that can operate a browser and execute code, available to Allegretto and higher-tier members.

Comparison with Similar Platforms
Unique Advantages
- K3's 1-million-token context allows you to feed an entire research report or a large codebase for analysis at once—a length rarely seen among domestic products
- Complete Agent capabilities: Deep Research, PPT, Website, Spreadsheets, Coding, and cloud-based Claw—not just a chatbot
- K3 is open source (2.8 trillion parameters), allowing developers to self-host or integrate via API on a pay-as-you-go basis
Practical Highlights
- Agent Swarm cluster mode supports up to 300 parallel sub-agents, making batch tasks highly efficient
- Kimi Code shares membership quota with the web version, so no separate subscription is needed for coding
Objective Limitations
- Advanced features consume quota, and heavy users need at least $19/month—more expensive than fully free options like Tencent Yuanbao and Tongyi
- K3's 1M-token context is only unlocked at Allegro ($99/month) or above; entry-level tiers only get the standard context
- Kimi Claw cloud instances continuously consume quota (about 0.6% per day). Remember to delete them when not in use to avoid unnecessary charges

Frequently Asked Questions
1. Is Kimi completely free?
No. There is a daily free quota for trial, but heavy daily use requires a membership subscription. Chat, Agent, and Code features all draw from the same quota pool and are billed by token.
2. How do I choose between K2.6 and K3?
Use K2.6 for quick Q&A to save quota. Use K3 for complex tasks, generating PPT/Word/Excel files, and multi-step Agent work. For very large-scale search or long-form writing, switch to K3 Cluster.
3. Can anyone use the 1-million-token context?
No. It requires an Allegro ($99/month) or Vivace ($199/month) membership. Moderato and Allegretto do not have access to K3's ultra-long conversation capability.
4. How long a PDF can be analyzed?
K3 supports up to about 1 million tokens (roughly 400,000–500,000 Chinese characters). K2.6 supports about 128K tokens per round (50,000–60,000 Chinese characters). The exact limit depends on the interface display.
5. What is the difference between Kimi Code and Cursor?
Kimi Code is a coding assistant bundled with a Kimi membership. Its quota is shared with the web version, and it runs on Kimi K3 under the hood. Cursor is a standalone IDE with more flexible model choices. If you already have a Kimi membership, you don't need to pay separately for Code.
6. What should I do when my quota runs out?
You have three options: wait for the next billing cycle to reset automatically, upgrade to a higher membership tier, or purchase a booster pack to continue on a pay-as-you-go basis. In-progress tasks will not be interrupted.
7. What is the relationship between Kimi and DeepSeek?
Kimi is a proprietary product of Moonshot AI, running on its own K2.6/K3 models. DeepSeek is a model from another company; the two are independent. K3 itself is open source, so developers can directly call the Kimi API or deploy it themselves.
