• 1B model: 0.0093 tok/sec

A few days ago, Alex shared a behind-the-scenes look on how it was made. The thread covers using FTP to transfer model weights and inference code to discovering how to build modern software for Windows 98:

On the topic of compiling for old hardware, Sam D’Amico shared DJGPP — a relatively modern port of GCC and interesting on its own!

React Scan by Aiden Bai automatically detects performance issues in React apps. From the website:

Previously, existing tools required lots of code change, lacked simple visual cues, and didn’t have a simple, portable API

Instead, React Scan:

• Requires no code changes – just drop it in
• Highlights exactly the components you need to optimize

React Scan will soon show what props caused a component to render as well:

And allow for recording and replying renders!
