“don’t train your own model” is common ai advice. it's wrong. your token bill's the proof. today, we’re excited to launch castform into open preview. castform is the easiest way for you to train your own model, on your own data. open-weights models are performant and much cheaper. when trained on your task & proprietary data, they beat closed models. the thing standing between you and that was weeks of plumbing & years of ml expertise. with castform, model training is as simple as prompt engineering. @castformai bring your agent traces or raw corpora. castform turns it into training data, picks the right algorithmic recipes, manages gpus, and gives you an ide to watch and chat with your model as it learns. see what you can build with castform👇

Finding the words to describe the style we want can be hard. It can be much easier to use an image. So, we are running some experiments for a feature like this. Let us know what you think!

just tried using @booplet_apps to make a mini app for chess coordinates training im not even good at writing prompts but it basically one-shotted ~90% of this right off the bat 🤯

Google launched Gemini 3.0 Flash two days ago, and we have already added it to @booplet_apps! ⚡️ From our tests, Gemini 3.0 Flash (Speedy) is wayyyy faster and almost as powerful as Gemini 3.0 Pro (Brainy). Here’s a Mario-like game that it one-shotted 🍄

Got to share my little @booplet_apps apps with a bunch of cool folks. Thanks @itsnotchester for organizing this demo sesh! Good to see @adilatwork @rachodoodles and friends again too ☺️

make fun little apps :) no waitlist, no invite code, just play

Fun morning vibe coding with @thorwebdev and @GoogleDeepMind ☕️

Marcel subscribed to Yeti Distro like 5 years ago, followed me, and now uses Booplet 🙇🏻‍♂️ The Internet is amazing.

I made this little grocery app for my wife and me, and it’s probably our most used app (besides messaging apps)! It’s like a todo list but nicer to have it not mixed with my todos. It’s like a shared Apple Note but much easier to clear the items.

I’ve been researching the app building space for a while and yeah most videos tell you how you can make $$$ by building apps. There’s a little corner of people making stuff just for fun, and it’s refreshing. I hope it grows! Bring back the 90s beautiful messiness!

It has been about 2 weeks since we have this new pwa beta, and it has been such a joy to make little apps on my phone. The medium (phone) makes it less stressful and more fun because I'm less pressured to make big, complex apps.

One unintended but interesting consequence of making so many little apps is I think about design a lot more. “The AI generated a button here but it’s better there” “Wait it’s missing this functionality” Iterating actual apps while using them has been surprisingly educational.

I have a sudden urge to revamp my entire personal website right now… But it’s almost midnight 😅

"Your strength is in choosing to work on something because it’s genuinely fun and interesting and you know you could be interested in it forever. This requires that you take it all personally."

We were sharing about little apps and why you should make little apps at @googlefordevs DevFest 🇸🇬 Little apps do little things Little apps are fast Little apps live in the moment Little apps connect people Little apps are quirky

Nice copy too!

We gave a sneak preview of the new @booplet_apps at the Singapore AI Showcase by @menloresearch this evening 👀

Made myself a screenshot studio to quickly beautify my screenshots 👨🏻‍🎨 This image was made with it. Screenshot-ception?

Fun day working on a habit tracker! There are a ton of habit trackers out there but this one is truly, truly editable :)
