SITUATION EXPLAINED: OpenAI solves a real math problem
In 1946, renowned mathematician Paul Erdős defined a simple problem: if you place n points in a plane, what is the maximum possible number of pairs of points that can be exactly 1 unit of distance apart? This problem, the planar unit distance problem, became one of the most well-known in the field of combinatorial geometry. Erdős conjectured that the “square lattice” solution shown below was more or less optimal.
An internal OpenAI model just disproved this conjecture, finding a more optimal solution. This is a big deal. This isn’t a literature review that found a previously unpublished human solution, or a slight improvement to an existing human solution, or a solution to some minor subproblem that no one cares about. It’s a fully AI-discovered novel solution to a well-known open problem central to a field of mathematics.
Just as crucially, the result came from a general-purpose reasoning model, not a model specifically designed for math like Google’s AlphaProof. It’s possible that this model is the next version of GPT-5.5 Pro, soon to be released to millions of ChatGPT subscribers worldwide. The dream of a genius in everyone’s pocket is one step closer to becoming a reality.
Introducing Composer 2.5, our most powerful model yet.
It's more intelligent, better at sustained work on long-running tasks, and more reliable at following complex instructions.
For the next week, we’re doubling the included usage of the model.
Excited to announce Battlespace Command, published by MicroProse Software.
Battlespace Command is an RTS depicting the full spectrum of modern war - from infantry to ballistic missiles - on massive 6,000,000 km² maps.

Surprisingly, found a nice way to write with AI:
1) apple notes for the raw draft
2) @linear agent to shape, iterate with my writing guidance
3) asking to create a doc to read, edit, comment on, and share
No more endless chat stream, full rewrites, or slow, blocky writing
@mariorod1 What have you been doing the past few months/years as this devolved? As CPO isn't this literally your daily pulse check and focus as you dictate features/priority?
Being the foundation for millions of developers means our bar must be higher for availability, reliability, and security. I’m sorry it’s been a rocky stretch at GitHub. We know we need to do better.
Today we published an update on two recent incidents: one on April 23 involving merge queue behavior, and one on April 27 affecting pull requests, issues, projects, and search-backed experiences.
We’re taking this seriously. We’re listening, and you have my commitment that we’ll communicate more frequently about the work underway to improve reliability and scale GitHub for what comes next.

@OfficialLoganK@firstadopter Need faster shipping speed, weekly or monthly iterations at minimum even if minor. You guys are losing the narrative due to the huge gaps in releases. Really rooting for you though. Even if the releases aren't best in class, the multi-month gap in drops erodes trust.
Cursor and SpaceX: In search of a complete loop
Quick notes on the deal:
- the new AI lab meta of needing to own product and model in coding
- why spacex and cursor need each other to close the loop
- beyond ipo timing why this structure is interesting

@BenjaminDEKR Writing is on the wall here, not sure why no one is seeing it: Vendor lock-in like Claude Code or Codex is fairly extreme as the UX of it all prevents drift from the technical users. That UX drives choice via comfort early, not later
It is interesting that SpaceX / xAI felt the need to acquire Cursor
Why not just build their own?
Actually, wasn't Grok Code / other upcoming Grok projects supposed to be this?
Grok 5 is supposed to be AGI, then isn't building an AI agentic code IDE in a few months easy?
@benln Trying, all pure native apps, currently just dogfooding internally. Support for Mac, iOS, Android, Windows. @getveld -- working through where AI fits in this flow currently without just slapping it in.
@nsbradford@cursor_ai Full Admin/Owner. On Team Settings, there is no setting anywhere that says 'Artifact' (doing a Search/Find on the page and that word doesn't exist)
@austinkettner@cursor_ai are you a team admin? what do you see on "Team Settings"? it should show the setting(s) but with the toggles disabled if you're not an admin, if not will fix
@austinkettner@cursor_ai should be in the Cloud Agent > Team > Pull Requests settings (can only be toggled by team admin), are you not seeing that? (feel free to DM me)
Today i learned, someone have created a SFP+ module to bypass AT&T Routers. the module have a open config, that allows you to copy paste the info from the AT&T config and bypass having to use the ISP routers
the module is 100$ and then you need a router with sfp+
