Running a 744B AI Model on Regular Hardware
Running a 744B AI Model on Regular Hardware
The Problem
Large AI models like GLM-5.2 have 744 billion parameters. These need huge amounts of memory - more than most computers have. These models normally require expensive servers that cost thousands of dollars.
Our Solution: Colibri
Colibri is a lightweight C program that runs massive AI models on regular computers with only 25 GB of RAM. The trick? It streams specialists from disk.
How It Works (Simple Version)
Think of a huge model as having many specialized "experts". Each expert is good at one thing:
- Expert 1: Good at math
- Expert 2: Good at writing
- Expert 3: Good at coding
For any question, only about 40 billion parameters are active (not all 744 billion). So:
1. Keep the most-used parts in RAM (about 10 GB)
2. Keep 19,456 specialized experts on disk
3. Load only the experts you need from disk (streaming)
4. Use a cache to keep hot experts ready
Real Performance Numbers
- Model size on disk: 370 GB (compressed to int4)
- Memory used: 9.9 GB RAM
- Load time: 30 seconds
- Speed: 0.05-0.1 tokens/second on regular hardware (with warm cache, faster)
- Can answer questions: Yes! Correctly!
Why This Matters
- Run 744B parameter models on a ~$500 computer
- No GPU needed (optional GPU makes it faster)
- Pure C code: one file, no dependencies
- Shows that huge AI doesn't need huge servers
The Honest Part
It's not fast compared to $100k GPU clusters. But it works, and it proves you can run frontier-class AI on a regular machine. The tradeoff: disk reads are slow, but the model stays correct.
