Section titled “Full transcript (original language)”00:00 Three new models available in Replit GPT-6 Soul, GPT-6 Luna Fast, and Claude Opus 5.5. Feel free to play around with these this weekend. You can always stay in auto mode and have Replit Agent pick the best model for you, but if you want to play around with some of these over the weekend, you can definitely do that. In particular, I’ve been seeing a lot of buzz around Claude Opus 5.5 around video generation and animation. Sam on our product team put out a really nice video on this. Ruth, I think. I saw a video from her building out animations and
00:34 videos with Opus 5.5. So, feel free to head over to the model picker and play around with that model this weekend. You can now build Replit apps from Muse. So, if you’re unfamiliar, Muse is Meta’s latest AI assistant. It’s getting a lot of traction. It’s been all over my feed as of late. So, you can go on to Muse, you can chat with Muse about your idea, and then when you’re ready, you can have Replit build out that application. Head over to connectors in Muse and look for the Replit connector. Just an FYI, this
01:09 is rolling out right now, so you may not see it right away, but just continue to go back to connectors and look for that Replit option. Did you know that you can vibe code your VR apps in Replit as well? You can vibe code virtual reality applications in Replit, and then you can connect it to your Meta device. So, fun way to build out new experiences. If you’ve been playing around with VR, please let me know in the chat. We’re going to be doing more on this front coming up, but go ahead and try that out, and would
01:41 love to see what you are all building there.
