The classroom changed. The homework changed. How we learn changed. 18 million students already build on Replit and now, there's a dedicated space just for them. No setup. No lectures. Just building. Teachers get free access. Students get 50% off Core. And if you're running a program, we'll help you scale it. Claim yours at replit.com/edu

Skip the slides. Build an app. Investors are vibe coding new versions of a company's website during the pitch. "This is what I would do differently." At work? Don't send a deck. Send a working app. Talking to a prospect? Don't write a requirements doc. Build a prototype. "Is this what you want? Cool. It'll be in the product in two days." Looking for a job? One guy got rejected by HR. He sent a vibe coded app to the CEO. Got called back the next day. Hired within five days. Now he's leading vibe coding projects at the company. If you're trying to get someone's attention, don't build slides. Build apps. w/ @landon20s

I look forward to welcoming you very soon!

5.5🤯 Try this “Go through the codebase like you own the company. Find what’s broken, risky, and quietly hurting the product. Fix the highest-leverage bugs with minimal changes, validate, and end with a GitHub PR: notes on what changed, why it mattered, and what needs follow up.”

We're watching AI evolve in real time. GPT-5.5 isn't just a launch - it's another proof point that the decade of intelligent systems is well underway. Congrats to the entire @OpenAI team on another impressive milestone. 🎉

1. We believe in iterative deployment; although GPT-5.5 is already a smart model, we expect rapid improvements. Iterative deployment is a big part of our safety strategy; we believe the world will be best equipped to win at the team sport of AI resilience this way. 2. We believe in democratization. We want people to be able to use lots of AI; we aim to have the most efficient models, the most efficient inference stack, and the most compute. We want our users to have access to the best technology and for everyone to have equal opportunity. We have been tracking cybersecurity as a preparedness category for a long time, and have built mitigations we believe in that enable us to make capable models broadly available. 3. We love you and we want you to win. We want to be a platform for every company, scientist, entrepreneur, and person. (My whole career has largely been about the magic of startups, and I think we are about to see that magic at hyperscale.)

Introducing GPT-5.5 A new class of intelligence for real work and powering agents, built to understand complex goals, use tools, check its work, and carry more tasks through to completion. It marks a new way of getting computer work done. Now available in ChatGPT and Codex.

we’ve come a long way 🤖 👨🏼‍💻

Excited to partner with the SpaceX team to scale up Composer. A meaningful step on our path to build the best place to code with AI.
