I’m proud to announce Hengshu, where instead of testing GPT Astra properly, I’ve whipped it to create omnidirectional Chinese poems 📜
Here are 3. First one rhymes and reads both horizontally and vertically: https://t.co/i6KEUNvDLP

Hey folks. Sotaku 2 is out! Timely, given the speculation about GPT Astra’s recurrence
Tldr: Sotaku is a tiny laptop-grade neural net that learns to solve sudoku without being given its rules. The broad goal is to see if we can solve bigger symbolic problems purely neurally, and

Remember how back in the crypto days folks asked "why can't we make these GPUs run useful work" and the typical answer is "making GPUs run useful work for money would defeat the purpose" and it turns out that's completely wrong in an important way

I invite you to re-examine your own domain carefully and see whether a tipping point is already here for you: how much of what we do, of our existing “best practice” patterns, should be rewritten to leverage a sufficiently smart coder? Ask your agent; you might be surprised!

As the quantity of code explodes in the next few years, I hope the folks worrying about quality can rest assured that there’s evidence that our ability to verify even the most casual vibe code can keep up with the amount of slop
Turns out that math was the ultimate spec

As a second order effect, the more we use tools like Freerange, the better the AI models become, because we’d feed it more correct code data & better reinforcement learning. What better to teach to AI, if not more practical maths?

The first day we introduced Freerange into our Midjourney codebase, we’ve caught 12 layout bugs that slipped through the best agents. Can’t really blame LLMs for not catching those across thousands of files and shaky floating point calculations.

But AI doesn’t care; it’ll cut through the thick layers made for humans and rewrite code as fast and as well as needed
The sweet spot of what constitutes “good code” is gradually shifting in the age of AI; we’ve been having delayed reactions

The idea of Freerange isn’t new at all; powerful provers exist already in the wild. Google’s AlphaProof gets smarter the more verification they threw at it. But pre-AI, it was rather unrealistic to ask a dev to:
- statically verify some dirty scripts when quickly iterating on

Another one, where we found a clash between your navigation bar size and the mobile site’s width. No more ugly mobile websites with bad column sizings! “number -> number” is the new “string -> string” https://t.co/pTkSrgVQKY

Consider this progress bar logic. What do we know about start and end here? Well they shouldn’t be equal. Otherwise you’re dividing by zero and BAM, you’d be carrying around an Infinity that pollutes everything downstream. Freerange audit catches this https://t.co/VRQGDRR90O

Your app has lots of numbers. If you ask “what do we know about these numbers”, most programming languages will tell you “not sure” or at best, “these are integers”. This doesn’t help you nor the AI agents

This paradigm is significantly more performant (~500x, but it's an unfair comparison; read on) than laying out text and messily crawl out the measurements through getBoundingClientRect(), which causes DOM read/write interleaving, one of the most expensive operations on the web
