3.7 is everyone's new favourite number

A look at everything going on in the world of Replit.

February 27, 2025

If you spent any time on X this week, you’ll have seen everyone going crazy over the release of Claude Sonnet 3.7.

Sonnet 3.5 is the model that powers all the AI coding apps - Replit included - and 3.7 is a bump in creativity and intelligence.

And, on the back of that Agent v2 has launched!

Just make sure you’ve got ‘Explorer’ mode enabled in your account settings.

Replit — [Early Access] Introducing Replit Agent v2

In partnership with Anthropic’s Claude 3.7 Sonnet launch, we're excited to announce the release of Replit Agent v2 in our early access program.

What’s interesting is, whereas some AI builders have just hotswapped in 3.7 to their tools, Replit has rebuilt Agent from the ground up to ensure better results.

And, as expected, Sonnet 3.7 now powers Assistant as well.

What’s new with Replit

Apart from that…

Deployments have got a repricing. TLDR; it’s getting more expensive to for autoscale and scheduled deployments, while reserved+dedicated deployments are getting a little cheaper.

Going forward there will also be a $1/month/deployment base cost.

Amjad gave the reasoning behind the increases in a tweet.

Finally, this interesting tweet from Replit President Michele Catasta hints at some sort of multi-agent mode coming soon.

Useful and interesting

For anyone that started building mobile apps after Replit’s Expo link up dropped, Matt Palmer just released the second part of his tutorial series. Here he goes over how to get your newly built mobile apps published in the iOS and Android stores.

Grok 3 was also released recently and with its “Think” mode, it’s turning out to be quite the proficient coding model - on par with with the o1 and Sonnet.

If you want to use Grok 3 to build stuff, then Replit to deploy, Matt has this tutorial for you to follow.

Also, if you hadn’t heard, Replit is running an ongoing competition giving away $1,000 to some of the best apps created with Replit. Next announcement is March 2nd.

Judging by my X feed, vibe coding games is in right now.

Also building on the go apparently.
