This paper from Stanford and Harvard explains why most "agent-based artificial intelligence" systems feel impressive during presentations but completely break down when used in real-world applications.

It's called "AI Agent Fine-Tuning," and it's the most important paper I've read this year.
Currently, everyone is obsessed with building autonomous agents. We give them tools, memory, and goals, and expect them to perform our tasks.
But when deployed in the real world, they hallucinate tool calls. They fail to plan long-term. They break down.
Here's why:
We try to cram all learning into the AI's brain.
When developers try to fix a broken agent, they usually just fine-tune the main model to produce better final answers.
Researchers discovered a deadly flaw in this approach.
If you only reward the AI for getting the final answer right, it becomes lazy.
It literally learns to stop using its tools. It tries to guess the answer instead of doing the work. It ignores the calculator and tries to do the math in its head.
To fix this, researchers proposed a new framework consisting of 4 parts for how agents actually learn.
And the most important conclusion completely flips the current paradigm.
Instead of retraining the large, expensive brain of the agent constantly, more reliable systems do the opposite.
They freeze the brain and adapt the tools.
They call it Tool Adaptation under Agent Supervision. #GateSquareAprilPostingChallenge $BTC
