it's important, i think, to resist the temptation to ship garbage

[OpenAI @OpenAI]

Today, we share a breakthrough on the planar unit distance problem, a famous open question first posed by Paul Erdős in 1946.

For nearly 80 years, mathematicians believed the best possible solutions looked roughly like square grids.

An OpenAI model has now disproved that belief, discovering an entirely new family of constructions that performs better.

This marks the first time AI has autonomously solved a prominent open problem central to a field of mathematics.

Composer 2.5 is built on the same open-source base as Composer 2, Moonshot’s Kimi K2.5.

[Gergely Orosz @GergelyOrosz]

AI - in theory - should make writing easier, thus expressing ideas should be a lot easier.

And yet, I don't see all that much more things that are worthwhile to read. Sure, there's a lot more junk. But I don't see more interesting eng blogs, personal tech-related blogs etc.

What is going on?

(Is this a discoverability issue? Or are people / teams not writing/sharing all that much more, indeed?)

[Brian Halligan @bhalligan]

I don't remember where I found this, but its spot on.

Introducing GPT-5.5

A new class of intelligence for real work and powering agents, built to understand complex goals, use tools, check its work, and carry more tasks through to completion. It marks a new way of getting computer work done.

Now available in ChatGPT and Codex.

[Sam Altman @sama]

Codex hit 4M active users, less than two weeks after hitting 3M.

We will reset rate limits today!

Day 2 at #GIDS and still going strong 🚀

Lots of interesting discussions around developer tools, innovation and how fast things are evolving.

More to explore, more to learn 👀

Introducing OpenMythos

An open-source, first-principles theoretical reconstruction of Claude Mythos, implemented in PyTorch.

The architecture instantiates a looped transformer with a Mixture-of-Experts (MoE) routing mechanism, enabling iterative depth via weight sharing and conditional computation across experts.

My implementation explores the hypothesis that recursive application of a fixed parameterized block, coupled with sparse expert activation, can yield improved efficiency–performance tradeoffs and emergent multi-step reasoning.

Opus 4.7 uses more thinking tokens, so we've increased rate limits for all subscribers to make up for it. Enjoy!

[BURKOV @burkov]

For those living under a rock: LLMs stopped becoming smarter around summer 2025.

Everything impressive you see since then is about finetuning them for specific tasks (mainly coding and software-tool-based task solving) and building tooling around them (such as agentic coding systems).

[Sachin Tripathi @snifhex]

@beffjezos 5.4 for plan and 5.3 codex xhigh for implementing the plan.

[ThePrimeagen @ThePrimeagen]

I don't think it is as big of a deal as people are making it.

Hype is annoying, anthropic please just IPO already.
