FAQ

Kimi K3 questions

Is Kimi K3 really a top model?
Yes, by independent benchmarks. Kimi K3 took the number one spot on the LMArena Frontend Code Arena, ahead of Claude Fable 5, and it lands in the top tier of the Artificial Analysis Intelligence Index, level with GPT-5.5 and Claude Opus 4.8. On the GDPval agentic benchmark it scores 1668 Elo, ahead of both GPT-5.5 and Opus 4.8. It is also the largest open weight model released so far, at 2.8 trillion parameters.
What is Kimi K3 best at?
Coding and agentic work. It tops the frontend coding arena and long running engineering benchmarks, and its 1 million token context holds whole codebases. For the deepest step by step reasoning, Claude Fable 5 and GPT-5.6 Sol still edge ahead, so reach for K3 to build and automate, and for those on the hardest logic puzzles.
How much does Kimi K3 cost on avots.ai?
Pay per use, no subscription. Input is billed at 3 USD per million tokens and output at 15 USD per million, the same rate Moonshot charges, and because K3 uses fewer tokens per answer a typical task lands near a euro. Top up from 0.99 EUR and the price is shown before every run.
What is the Kimi K3 context window?
1,048,576 tokens, about one million, one of the largest available. Entire repositories, long PDFs or months of chat history fit in a single prompt, so K3 keeps the whole picture in view instead of forgetting the start.
Can I use Kimi K3 with GPT-5 and Claude on one balance?
Yes. avots.ai is one balance for 40+ models. Chat with Kimi K3, GPT-5, Claude Opus 4.8, Gemini and DeepSeek, generate with Veo, Sora and Nano Banana, all from the same top up, in the web app, Telegram, MCP or the API.
