Kimi AI Quick Summary
Overall Rating: 4.2/5
Best For: People who want an AI agent for research, documents, slides and websites, with a free plan and paid plans from $19/month
How Kimi Chat Works: K3.1 Pro, K3 and Long Context
Kimi Chat runs on Kimi K3.1 Pro, which has just launched, and on K3. Because K3.1 Pro is new, the purchase notice warns that requests may queue or fail at launch, and that wait times vary with overall load. The K3 series models support a 1,048,576-token context window, and the Max and Ultra plans offer up to 1M tokens of context for ultra-long conversations. A paid membership unlocks faster models, higher concurrency and more powerful research preview capabilities, and Pro and above add access to K3.1 Pro Highspeed. The interface is built around tasking agents rather than plain chat, with Plugins, Scheduled tasks, Deep Research, Build and Kimi Code available on paid plans. If you are weighing chat assistants, you can read our ChatGPT review alongside this one.
Who Is Kimi AI Best For? Researchers, Builders and Power Users

Kimi Agent Features: Goal Mode, Swarm, Deep Research and Websites
Agent Tasks and Goal Mode
Kimi supports agent multi-tasking, so several agent tasks can run at once. Goal mode, available on Pro and above, lets agents work autonomously until completion. Concurrent agent tasks are 1 on Free, 2 on Plus and Pro, and 4 on Max and Ultra.
Hand off a goal and let the agent carry it through to the end.
Swarm
Swarm runs multiple agents together on a task. The number of running subtasks is 2 on Free, 4 on Plus, and 8 on Pro, Max and Ultra, so the higher tiers let more agents work in parallel.
Split a job across several agents instead of running one at a time.
Deep Research
Deep Research is included on paid plans, with more powerful research preview capabilities unlocked by membership. If you want a tool built specifically around AI research, our Perplexity assistant review covers that option.
Run research inside Kimi, or compare it with a dedicated research tool.
Documents, Spreadsheets and Slides
All paid plans list working with documents, spreadsheets and slides, plus 3D Modeling / 3D Web. That means office files and 3D web work are handled inside the same product rather than through separate apps.
Work on documents, sheets, slides and 3D web in one place.
Scheduled Tasks and Dashboard
Scheduled tasks run automatically and push results to you. The allowance is 2 on Free, 10 on Plus, 15 on Pro, 20 on Max and 25 on Ultra. A dashboard with task widgets keeps those runs visible.
Set recurring work once and let it run and report back.
Websites and Kimi Claw
Kimi can build and publish websites with database support. On Pro and above you can deploy your Kimi Claw in one click, putting a working site or agent live without a separate setup process.
Go from building a site to publishing it inside Kimi.
Kimi Code and the Kimi API for Developers
Kimi Code is available on paid Kimi plans, including Plus, Pro, Max and Ultra. For a closer look at how it compares with Claude Code, see our Kimi Code vs Claude Code comparison.

- Step 2: Try an agent task or set up a scheduled task that runs automatically and pushes results.
- Step 3: If you need Deep Research, website deployment, or more projects, compare Plus ($19/month, or $15/month billed annually) with Pro ($39/month, or $31/month billed annually).

Is a Kimi Subscription Plan Worth It? Plus vs Pro vs Max
The Free plan is enough to try one agent task, two scheduled tasks and two projects. Plus at $19/month ($15 billed annually) is worth it for Deep Research, website deployment and Swarm, with 2 concurrent agent tasks and 10 scheduled tasks. Pro at $39/month ($31 billed annually) adds Goal mode, where agents autonomously work until completion, K3.1 Pro Highspeed and one-click deployment of your Kimi Claw, plus 15 scheduled tasks. Max at $99/month ($79 billed annually) only makes sense if you need up to 1M tokens of context for ultra-long conversations and 4 concurrent agent tasks, with 5x agent credits and 20 scheduled tasks. Ultra at $199/month ($159 billed annually) is for 10x agent credits and 25 scheduled tasks. Kimi Code is available on paid plans. Annual billing is advertised as saving up to $480.
