AI in 6502 Assembly? It Actually Works

Remember when CPUs were 8-bit and programming was a true art of survival? Turns out, you can still run artificial intelligence on such ancient hardware. One brave developer took 6502 Assembly — the language behind Commodore 64 and Apple II — and made it work with modern AI models.

How does it work?

The 6502 processor, released in 1975, processes 8-bit values through memory and simple control flow. But the project's author used Claude Code Skill to adapt assembly code for interacting with neural networks. The result? The AI not only booted but also performed tasks — albeit not at lightning speed.

This experiment isn't a practical solution but a demonstration that even on constrained hardware, you can implement modern algorithms. For developers, it's a reminder: don't write off old tech — it can offer unexpected insights.

Of course, running an AI assistant on a 6502 in production is a terrible idea. But as a hobby project or a way to understand neural networks at the lowest level, it's a great challenge.
