What is Kimi?
Kimi is an AI assistant created by Moonshot AI, a Chinese AI company founded in 2023. It's famous for one thing above all else: massive context windows.
While most AI assistants struggle with documents longer than 50 pages, Kimi can handle:
- 200K tokens (approximately 150,000 words or 300+ pages)
- Some versions support up to 2 million tokens
- Multiple large documents simultaneously
Think of Kimi as the AI that actually remembers your entire book, contract, or research paper.
✅ Prerequisites Checklist
Before starting, ensure you have:
Moonshot AI Background
Company Overview
- Founded: 2023 by Yang Zhilin (ex-Google Brain)
- Headquarters: Beijing, China
- Focus: Long-context language models
- Funding: $1B+ valuation (2024)
Why Long Context Matters
Most AI assistants have a "memory limit" — they can only consider a certain amount of text at once:
| AI Assistant | Context Window | Approximate Pages |
|---|
| ChatGPT (Free) | 8K tokens | ~6 pages |
| ChatGPT (Plus) | 128K tokens | ~100 pages |
| Claude (Free) | 200K tokens | ~150 pages |
| Claude (Pro) | 200K tokens | ~150 pages |
| Kimi | 200K-2M tokens | ~150-1500 pages |
What This Means in Practice
With ChatGPT: Upload a 50-page report → AI forgets the first half by the time it reads the end
With Kimi: Upload a 300-page book → AI remembers everything, can cross-reference chapter 1 and chapter 20
