“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👇

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
