If Anthropic put out a $1000/month tier that gets 5x the $200 tier limits and also lets us keep Fable access, I'd do it in a heartbeat.

When I woke up, I decided to check my laptop quick to see if I could fix anything quickly before showering and starting my day. It's now 7pm. I got through over 100 PRs. I haven't moved from my desk. I still haven't put pants on.

I was frustrated by the image generation experiences in existing apps. Including ours. That's why I spent almost a year playing with alternative UX. Today, we finally have something to show for it. Introducing T3 Canvas, the world's best image generation experience.

My thoughts on Sonnet 4.6 (trust me, this one's important)

T3 Chat now has profiles! I've wanted this feature for so damn long. I have lots of different use cases for T3 Chat. Being totally honest, I don't want you guys all seeing my "personal" ones. FINALLY I HAVE A PLACE FOR THEM. You can customize your profiles for different use cases. Tell the work one what tech you use. Tell the personal one a bit about yourself. I'm honestly surprised no other chat apps have built this yet, I've been loving it. This is only DAY ONE OF LAUNCH WEEK! Lots more fun stuff coming soon :)

you can tell when theo didn't build something, he switches from "i" to "we"
T3 Chat Launch Week officially starts on Monday, but we wanted to get this out first. We just overhauled how credits work on T3 Chat. No more "standard" and "premium" credits. Now you have a "usage" bar that resets every 4 hours. You'll never be more than a few hours away from sending more messages. This change is meant to align your usage with our actual costs. Using a fancy model for a simple question? Costs almost nothing. Using Gemini 3 Pro to analyze giant PDFs in 20-message threads? That will eat your usage fast. For reasonable users, this should be a SIGNIFICANT increase in how many messages you can send per month. The goal of this change was to balance out costs and reduce "fear of running out". If you're not dumping your entire codebase into T3 Chat as context, you should never have to worry about limits again. For those who previously purchased premium credits, they are still available and will be used when you go over your existing limits. We also have a small gift for those who used a lot of premium credits (check your email later today for more info) These changes unblock some very exciting things in the near future, so keep your eyes peeled for that 👀
