WHY WE PICKED IT
Kimi k1.5 is the first model to prove that o1-level reasoning is achievable through efficient, open-weight architectures. We selected it because it consistently matches or exceeds Claude 4.5 in technical benchmarks (AIME, MATH-500) while offering a 2M context window and a significantly lower API price point, making frontier intelligence accessible to everyone.
GETTING STARTED
Start using Kimi k1.5 for free at kimi.moonshot.cn, where you can leverage the full 2M context window. For developers, the Moonshot AI platform (platform.moonshot.cn) offers API access at a fraction of the cost of Claude or GPT models. You can also explore the model weights on GitHub for local deployment.
QUICK TIPS

Q
How does Kimi k1.5 compare to Claude 4.5 and GPT-5.2 Codex?
A
Kimi k1.5 matches or exceeds Claude 4.5 and GPT-5.2 Codex on major technical benchmarks like AIME and MATH-500. It achieves this frontier-level reasoning at a significantly lower cost—often 1/100th the price—while remaining open-weight, proving that the 'DeepSeek effect' is the new standard for AI efficiency.
Q
Why is Kimi k1.5 considered the 'Next DeepSeek' movement?
A
Kimi k1.5 is the spearhead of the movement toward high-efficiency, open-weight models that disrupt the proprietary monopoly. By matching the world's most expensive models (like Claude 4.5) while being significantly cheaper and transparent, it democratizes frontier intelligence for developers and researchers worldwide.
Q
What is the advantage of Kimi's 2M context window over Claude 4.5?
A
While Claude 4.5 is powerful, Kimi k1.5's massive 2 million token context window allows it to process entire codebases or hundreds of technical documents in a single prompt. This makes it superior for deep-dive analysis and complex project migrations that exceed the limits of closed-source models.
Q
How do I use Kimi k1.5?
A
Kimi k1.5 is a large language model for text generation, analysis, and conversation. Access through the web interface. Enter prompts or questions to get responses. It excels at matches gpt-5.2 codex in technical reasoning benchmarks.
