building Bitfield - world's fastest plug-in runtime and database for founders that want their product to get huge without AI spaghetti code slowing them down.




ngl social media is hella boring when you go do life outside for a day

We found and fixed two issues that could explain this degradation of the capability of GPT-5.5 in Codex over the last ~ 48 hours. We are monitoring over the coming hours to fully confirm and I will reset usage limits this evening. Apologies and now is the time for /fast maxxing.





Codex team is aware of reports of GPT-5.5 performing worse for some users and investigating. We don't have anything conclusive yet and systems are healthy but we will share updates as we go.


General Catalyst just co-led a $31.5 million seed round into a blatant rip-off of my company, Kled. (skip to 40 seconds if you want to skip context) I would typically not speak on things like this, but this level of blatant copycatting is egregious and completely unacceptable, and needs to be made an example of. This is one of hundreds of YC startups who have conducted this disgusting behavior. Unimaginative slop that continues to get rewarded due to nepotism.





I can't help but feel personally burned by the Claude Code changes announced today. We put so much work into wrapping the (atrocious) Claude Agent SDK in T3 Code. It was the ONLY path they supported, so we made it work. It was hell. Now our users are getting their rate limits cut by 40x, despite us doing everything right. I listened to the Claude Code team. I had my issues with their direction, but I trusted them and took them at their word. I will never make that mistake again. Until we see significant change, it is safe to assume any statement from an Anthropic employee is a lie on a timer. The rug will be pulled, no matter how many promises are made beforehand.


Cal AI's stack is almost 100% built with in-house tools. No serious off-the-shelf tools. If we needed something, we built it. Every dollar of dependency was a dollar of slowdown. Every "we'll wait for X to ship Y" was a chunk of a quarter we couldn't get back. No one was working as hard as us. No one needed to. We just couldn't afford to wait.
