Pros & Cons
Pros
- Frontier level performance at a fraction of the cost of GPT-5.2, Claude Opus 4.6, and Gemini Pro 3.1
- Open source weights under Modified MIT License; you can self-host, fine-tune, and inspect the model
- Agent Swarm is a genuinely novel capability: up to 100 parallel agents coordinating without predefined roles
- Best in class multimodal vision with highest scores on 9 out of 17 image and video benchmarks versus top competitors
- 256K token context window handles very long documents and entire codebases in a single session
- Available globally with English interface, USD API pricing, and distribution through US based providers (Fireworks, OpenRouter)
- Kimi Code provides a free, open source CLI coding agent comparable to Claude Code with MCP support
- Input caching at $0.10 per million tokens dramatically reduces costs for repeated or iterative tasks
Cons
- Newer and less established than ChatGPT, Claude, or Gemini with a smaller community and fewer integrations
- Consumer app ecosystem is less mature; fewer features like memory, projects, or connectors compared to Claude or ChatGPT
- WeirdML benchmark score of 46% suggests weaker performance on unusual or edge case reasoning compared to competitors
- Agent Swarm is still in beta; expect rough edges and inconsistent results on some tasks
- Documentation and support resources are less comprehensive than those from OpenAI or Anthropic
- The company is based in Beijing, which may raise data residency or regulatory concerns for some organizations (though US based API providers like Fireworks mitigate this)
- Paid consumer plan details are less transparent than competitors; pricing may vary by region
- Consumer app writing quality does not yet match Claude for nuanced, natural sounding prose
How to get started
Create your account
Go to kimi.com and create a free account. The interface is available in English. You can also download the iOS or Android app for mobile access. The free tier (Adagio) provides unlimited basic conversations with limited Deep Research and Agent tasks.
Send your first message and explore operating modes
Type a question, upload a document, or describe a task. Switch between Instant (fast responses), Thinking (deeper reasoning), Agent (autonomous task completion), and Agent Swarm (parallel multi-agent orchestration) using the mode selector. Try Agent mode for research tasks or Thinking mode for complex analysis.
Try key features
Activate Agent Swarm (beta) for large scale tasks that benefit from parallel investigation. Use Deep Research for autonomous web research with source citations. For developers, sign up at platform.moonshot.ai for API access or use K2.5 through OpenRouter, Fireworks, or Together AI if you prefer a US based provider. Install Kimi Code from GitHub for a terminal based coding experience.
Upgrade or access the API when ready
The free tier is generous for everyday conversations. Upgrade to the paid plan (~$19/month) when you need higher limits for Deep Research, Agent mode, and Agent Swarm. For developers, the K2.5 API at $0.60/$3.00 per million input/output tokens offers frontier level performance at dramatically lower cost than GPT-5.2 or Claude Opus.
