*Test for overfitting: this is a verification whether the tested model is really capable to solve any complex problem, or it is ’just’ trained to solve the given problems in public set.

The problems are divided into three subsets:
🔹 Public: 731 instances openly available on the Hugging Face platform
🔹 Commercial: 276 instances sourced from startup repositories; only the results are publicly accessible
🔹 Held-Out: 858 problems that mirror the public set, used to test for overfitting
🔹 Public: 731 instances openly available on the Hugging Face platform
🔹 Commercial: 276 instances sourced from startup repositories; only the results are publicly accessible
🔹 Held-Out: 858 problems that mirror the public set, used to test for overfitting

AI models' performance are evaluated using benchmarks. One such benchmark is SWE-Bench Pro.
SWE-Bench Pro consists of 1,865 software development problems, designed as long-horizon tasks. These tasks can take professional software engineers anywhere from hours to days to complete.

AI Wearables: The Race Is On
Meta acquired Limitless.
Amazon bought Bee.
OpenAI is developing AI wearable hardware.
Big Tech isn’t just predicting the future, it’s shaping it.
But there’s still room for AI wearable startups to offer ‘bigtechless’ solutions for customers who value privacy.

In my latest newsletter, I wrote about the myth of the "perfect prompt."
TL;DR: It doesn’t exist.
I don’t believe in one-step solutions. No matter how complex or well-crafted a prompt is, it can’t magically instruct an AI to solve a complex problem in a single go.
