Gemini showed up in my Google Chrome today. They launched this at Google I/0. It's basically just quick access to Gemini but you can share a tab which can open up some interesting workflows.

I was using Replit to try and prototype something and it was not working at all. A funny thing happened where it created a test page to try to help. Something about that process just really blew my mind. I do the same thing all the time during troubleshooting

BREAKING 🚨: Gemini Pro users are getting access to 3 Veo 3 Fast generations per day instead of a 1-time, 10-pack that was previously available.

In addition to a bunch of other updates to Flow and more.

Trying out something with Veo3.

I spent a lot of time with Codex and Jules by Google. It feels pretty crazy to be able to walk away and have some work done for you when you get back. I still keep using it on very basic projects so the completion rate was pretty high. Has anybody used it and had good results?

ChatGPT Codex rolled out to Plus users today. I finally got a chance to sit down with it for a little bit. I tried it on a very simple project but you can see that this feels like the next shift. chatgpt.com/codex
