OK folks, today is the day when I reveal what this tweet was about. We made MCP work better by: 1. Convert the MCP tools into a TypeScript API 2. Tell the agent to write code against this API We call it "code mode" It uses a new feature in Workers: Dynamic Worker Loading

I think congrats again to OpenAI for cooking with GPT-5 Pro. This is the third time I've struggled on something complex/gnarly for an hour on and off with CC, then 5 Pro goes off for 10 minutes and comes back with code that works out of the box. I had CC read the 5 Pro version…
Hey, I made this chart and this is what my team has been working on the last year. Happy to share more thoughts about our strategy beyond LOC. While this is a super-simple metric to understand, it's not the only measure. Turns out AI also causes a lot of devx pain 🧵

Still think about this post all the time.
The reason we care about ordering so much is that LLMs, even in 2025, prioritise information at the start and the end of their prompts. So while all information you pass to an LLM should be important, the MOST important stuff should be at the start and the end.

@aramh Speak for yourself. Absolute joy from using a terminal matters a lot to me.
Wrap your head around this. - Have git spit out a file's edit history - Line up all the diffs one-after-another - Feed it to a model and tell it to recreate the current (last) state At 100,000 tokens, Sonnet 4 succeeds 2/3 of the time, while GPT-5 does <5%.

Millions of (largely anon) retail investors really front ran Wall Street in size while they fudded their bags for a decade. People will say you got lucky, but hodling BTC to here was not easy. Bitcoin really taught a generation of investors to be comfortable as a contrarian.
We raised $60M for this moment: Introducing Slash Global USD (in partnership w/ @base). It's the first banking platform that lets you open a USD account without an LLC, EIN, or the rampant account closures they call "account safety". It took major legislative changes AND 3…
This is crazy. I just sat here, mouth open. I was debugging a very very strange bug, a regression. For one hour. While talking to colleagues inbetween. The oracle ran in the background. For 45min! I thought it got stuck. Then it comes back with this. And it was correct.
imo the bottleneck for using LLMs today is “how do I give it the right context & feedback loop to do this well?” and not “can it do this?”
