Being at top of @OpenAI token usage list is a vanity metric. Our job as engineers is to minimize token usage (aka latency and cost) while maximizing value by precise tool definitions and clever model routing. My dream is to grow arr and move lower on this list…

@NotionHQ has processed (well over) a trillion tokens on @OpenAI , and now we have this cool token to show for it.

Hiii. Just moved to SF and passionate about coding and startups. I love to travel and do pattern recognition. Hit me up if you want to get coffee.

A lot of work goes into defining tool calls for agents. Moving the team from thinking about few-shots (gpt-4 era) to tool definitions (sonnet4/gpt-5 era) has been a company-wide initiative that has unleashed major step-change capabilities. Advice - organize your work around

how did @NotionHQ cook so hard with their agent harness? it's insane, and the underlying models are Sonnet 4 and GPT-5?! idk how it's able to tool call so well, and mind-read on requests and just oneshot pretty much everything???

We're spending the day at @NotionHQ sprinting in person with @OpenAI on optimizing #GPT5 for low-latency solutions that optimize tool call accuracy. Exciting things coming soon - we love having in-person time with our partners!

Couldn’t agree more. Except our ROI is slightly better than roulette.

Absolutely - when you want exhaustive tasks, long horizon planning, or parallel tool calling, thinking is great. But sometimes too much (err, overthinking?) is just a slow, shitty experience for users and a waste of money.

Agents are all figuring out the web and having their AOL moment, relearning search for agent-first environments. In two years, this will feel like table stakes. In the meantime, I sat down with @paraga/@p0 and @DhruvBatra_ /@yutori_ai on how we get there.
