SEAL is a game-changer in the world of Artificial Intelligence. The SEAL framework lets large models learn from their own notes and trial-and-error — without needing a huge team of engineers. That’s a big deal. It means we’re seeing the first sparks of an “AI that evolves by itself.”
What Exactly Is SEAL?
SEAL stands for Self-Adapting Large Language Model. It lets a chatbot become its own teacher. The team from MIT designed SEAL to generate its own “self-edits”— instructions to create training data and adjust its own parameters.

This means SEAL can improve without needing humans to feed it more data. It evolves and grows smarter all by itself.
How SEAL Learns
Here’s how it works. SEAL starts by trying something — solving a puzzle or a knowledge task. If it performs badly, it checks its own mistakes and generates a set of instructions to learn from.
This trial-and-error forms a reinforcement loop. SEAL gets rewarded when it performs well and adjusts when it performs badly. Over time, it starts solving more problems with greater accuracy.

Why It’s So Huge
The results are wild. SEAL jumped from 0% to 72.5% on puzzle-solving tasks. That’s a huge improvement. It also performed better on knowledge questions than when it was trained with materials from GPT-4.1.
This shows something powerful — a large model can outperform methods designed by humans, simply by teaching itself.
Why Should We Care?
SEAL brings us a step closer to something called superintelligence — a future where machines can improve and innovate without human intervention.
Some say it’s a little scary. But it’s also a huge opportunity. SEAL could be a key to developing smarter, cheaper, and more adaptable AI systems.
The Future Is Here — Are We Ready?
SEAL is a dramatic breakthrough. It highlights the potential of letting machines learn from their own experience.
Some companies, like Sakana’s DGM framework, are exploring this path already. The future might be filled with AIs that grow smarter by trial and error — just like humans do.
