“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👇

incredible launch video - very very original concept - founder is super authentic and compelling when he talks - elite editing given how few different shots there are - animation on the character is spectacular. looks like a pro worked on this. - dialog between founder and character is great and paced nicely - brilliant idea focusing on key questions people ask about their space - sound fx and music is solid - great scroll stopper, bold statement, social proof, etc but - only feedback is to add captions this is might be my favorite launch video of last 6 months. the biggest thing they nail is simply copying a PROVEN format from YouTube/film/TV. the physical board with google queries on it is something I've seen on tons of YT videos but have never seen on a launch video. and the animated character closely parallels pixar's characters. had they tried to change even a small piece of this or not executed it well, this wouldn't have hit as hard. not only is this an easy hack for coming up with video ideas, but it ALWAYS works. Founders Fund just did it with reality TV, TBPN did it with ESPN. spectacular work

Happy Friday @pauldesign

We’ve decided to gather together the best builders in the bay… on the bay. Our 89-foot yacht will bring together the 30 best applicants to have them battle it out as we sail out under the bridge for a final sunset demo. Is this a good idea? A terrible one? Who knows. But @composio along with @nebiusai and @tavilyai is determined to find out. And the winner is taking home a DGX Spark and $50k in credits. Apply by posting what you’ve built and tagging @ship_builders, @composio, @nebiusai, @tavilyai
