I still remember the day Michele (aka pirroh@) became a full time member of Replit instead of just an advisor. Or, in his words: "stopped just yapping and came to get things done".
Game changing since day 1. Awesome to watch you do your thing @pirroh.
The greatest inventions end up in the same place: in ordinary hands, doing extraordinary things.
For 20 years, President & Head of AI Michele Catasta chased this vision. Now, he's built it. This is the story behind Free Mode.

You can access OpenAI models on Replit for free.
Our router also makes high-end models incredibly cost-efficient.
If you’re a business looking for an independent, multi-model alternative to Cursor, we’d be happy to fund your transition.
We’re ending our partnership with Cursor following its acquisition by SpaceX. Under our proposal, Cursor’s direct access to our models would end on November 12.
We know that the people most affected by this decision are the developers who rely on OpenAI models in Cursor. We care about their experience in this transition and we’re ready to go above and beyond to support them.

Instead of expecting every employee to choose the correct model for a given task, let Replit do it for them.
Less token spend, same outcomes.
Quality, speed, efficiency. Now you get all three, without having to choose.
Intelligent Model Routing picks the best model for every task, so you don’t have to.
That means top tier output for up to 65% less cost. 0 effort spent switching models.

This is the way.
I have only put one motivational message on my desk for the past 16 years.
I take no credit for it, it was a sticker I got a tech event in 2010 for a defunct startup.
I’ve turned it into a 3d print last year and have a few laying around the house to remind myself that no meeting matters, no planning doc matters. All that matters is the feedback you get from shipping so you can ship again. 🚢

Every builder should get the benefit of a full modern software engineering team. That includes application security engineering and penetration testing.
Enjoy building more safely!
You can now run black-box pen tests for your Replit apps.
Security scans that test your Replit apps the way external attackers do.
Replit Agent can fix what it finds in a single click.

Sharing a major part of the secret sauce in our Self Driving Company story.
We built a self-driving & self-correcting shared semantic layer on top of our databases, conversations, and docs.
Everything is queryable & joinable—regardless of source!
So now anyone at Replit can ask questions that previously needed a team of data scientists weeks of work.

Sandboxes are hard.
With all the “AI escaping sandbox” it’s easy to think “wow AI so scary,” but most AI companies, and recent “sandbox providers” are making very basic mistakes.
At Replit we’ve been running sandboxes since 2016 and targeted by every hacker and state actor under the sun. So we learned a thing or two.
Main advice: Assume zero-days exist — because they do — and think in layers of protection in a zero-trust framework.

My favorite feature is comparing multiple models in parallel. Helps you create anti-slop designs and always keep up with the latest capabilities.
Meet Replit Design ✨
Built to be the best place to design with AI, with an agent that feels like a true design partner
I’ve spent most of the past year working on making @Replit the best place to go from exploration to reality. Can't wait to see what y'all make 🤗

LLMs benefit greatly from an open ecosystem and it’s the best way to ensure America stays competitive.
Replit has been committed to supporting an open ecosystem since we first released our open coding model in 2023 (one of the first on the market).
Our letter to congress:
For my first post, I’m sharing a letter @NVIDIA signed on why open models matter.
AI will transform every industry, power every company, and be built by every country.
Open models strengthen safety and cybersecurity, accelerate innovation and diffusion, and enable sovereignty.
The world needs both frontier closed models and frontier open models.

For those of you that like to inspect pricing pages and compare platforms on cost (like me), you are going to be impressed.
We want to make it easy for you to build, host and scale, all in one place.
So we cut prices for hosting apps on Replit.
Prices for apps running at scale will drop by more than 50%, starting Aug 1.

I'm so proud of this partnership with @Replit and the massive number of developers that we're protecting every day.
8,000 malicious packages blocked per day for Replit developers!
Blocking the bad and removing the noise.
Our @SocketSecurity partnership blocks ~8,000 malicious packages a day and filters out 30% of false-positive critical vulnerability alerts, the ones that were never exploitable.
We focus on security so you can focus on building.

Secure by default should be the default model for all modern software development, especially given the supply chain attack volume has been relentless in the past months!
@Replit is leading by example here, very proud to help protect such a massive number of developers every day.
