FAQ

Frequently Asked Questions About Kimi K2

Real answers from real developers using Kimi K2 in production

1

What is Kimi K2 and how is it different from other AI models?

Good question! Kimi K2 is a trillion-parameter beast that only wakes up 32B parameters when you need them (that's the MoE magic). Unlike other models that promise the moon, Kimi K2 actually delivers—especially for coding. We're talking 53.7% on LiveCodeBench while others are stuck in the 40s.

2

How does the credit system work?

Super simple: 1 message = 1 credit. Try Kimi K2 free with 10 messages (no signup needed). Create an account and boom—20 credits in your pocket. Invite friends and watch the credits roll in: 20 when they join, 100 when they subscribe. It's like a referral program that actually works.

3

Can I use Kimi K2 for commercial projects?

Absolutely! Grab an API key and ship Kimi K2 in your products today. We've got startups using it for customer support, enterprises for code review, and everything in between. Commercial use is not just allowed—it's encouraged.

4

What programming languages does Kimi K2 support?

Name a language, Kimi K2 probably speaks it fluently. Python, JavaScript, Go, Rust, even COBOL if you're into that. But here's the kicker—Kimi K2 doesn't just write code, it understands idioms, best practices, and can even explain why that regex is a bad idea.

5

How long can my conversations be with the context windows?

Kimi K2 offers 128K tokens for most tasks, while the new Kimi K2 0905 model doubles down with 256K tokens—that's two novels worth of context. Choose the model that fits your needs: standard Kimi K2 for regular projects or Kimi K2 0905 for massive codebases.

6

Is my data safe and private when using Kimi K2?

We get it—nobody wants their secret sauce leaked. Your conversations with Kimi K2 are encrypted end-to-end. We don't train on your data (pinky promise). Want to vanish? Delete everything with one click. Enterprise folks get even more: SOC2, HIPAA compliance, the works.

7

What's new in the Kimi K2 0905 model?

Kimi K2 0905 is our latest powerhouse release. We doubled the context window to 256K tokens, cranked up the coding performance (69.2% on SWE-Bench!), and seriously improved frontend development capabilities. Same lightning speed, twice the memory, and better at shipping production code than ever before.

8

Does Kimi K2 have access to real-time information?

You bet! Unlike models stuck in the past, Kimi K2's ultrathink web search brings you the latest news, stock prices, weather, and current events.
