omg the ultimate @lucia.red and @t3.gg collab... produced this beauty :O it's awesome how T3 Chat started by focusing on being strong technically, strong in price to value, only then tackled the looks... and boy is it beautiful, just the right touch of aesthetics, without being over the top 💜🔮

If @t3.gg is excited about CSS Functions, then so should you. youtu.be/gj2REv4D380?... (Also see my second revision of --light-dark() that uses if() and style queries to properly mimic the native light-dark() — brm.us/at-function-...)

I've been using @t3.gg 's T3 Chat for a while now - logged in, unpaid, and yah. Fast responses from a chat bot make a huge difference. It's one of those things that you'd think doesn't matter that much until you use it t3.chat/chat

For LLM chat you may want to consider t3 Chat by @t3.gg and team. t3.chat I canceled my personal Chatgpt account for $20 a month in favor of this for $8, which has access to many LLMs. Very pleasant so far!

I'm not really the "tutorial guy" on YouTube. I have 3 total, 1 per year. I wanted to give it another go - but I wanted something different. Less copy paste, more introspective on my dev process. Never done anything like this before. Just released it for free with no ads on YT

@t3.gg made a great informative video about all the different ways we render html on the browser. It’s not performing super well so lets show some love because this is the kind of video that goes a long way in educating rather being a part of a content factory youtu.be/Cifkb-ZVps4

I've spent the last 48 hours handling DDOS attempts, fixing weird error cases, rebuilding rate limiting, and generally shipping. Really proud of where we landed. Over 500,000 messages have been sent since we launched T3 Chat. I just 4x'd the guest tier limits to celebrate!
