Those are your input tokens.Then, during decode, it writes output tokens: its thinking, the tool calls it makes, and the text you see. This happens one token at a…

Sebastian Bubeck asked me to talk a bit about the future we'd all like to avoid, where humans are mathematically disempowered. Jacob Tsimerman advised us to try to prioritize detail over correctness, and I have no doubt that I succeeded in deprioritizing correctness. I tried to find a title that wasn't too bombastic: The premise of the workshop (which we took as a starting point, rather than subject to debate,…

I replied with my full legal name, Sean Joseph Byrne, uploaded my driverโs license, and pointed out the address on the government record they appeared to be matching me…

**What Youโll Learn**: Microsoftโs move isnโt surprising, as Edge is based on Chromium, the open-source browser engine that powers most web browsers today, including Opera, Brave, Vivaldi, and Samsung Browser. Google initiated the migration from Manifest V2 to V3 in Chrome/Chromium, and Microsoft Edge is now following Googleโs lead. But Firefox is one of the few web browsers remaining that isnโt based on Chromium, and itโs now the only major browser to still support uBlock Origin. Neither Safari nor DuckDuckGoโthe two other major non-Chromium browsers out thereโsupport…

I'm tired of reviewing one, two, three thousand line PRs because some agent was able to "one shot the whole issue." Small PRs were never asked for because they're easier to write, it's always been for the benefit of the reviewer. AI is such a boon to the industry, but it's becoming such a liability for reviewers and maintainers. Maybe I'm just an old man yelling at the clouds, but please, stop sending me huge PRs.
