If you are building on top of giant closed models and haven't lost any sleep over their economics, you aren't paying attention. The way forward is small, efficient models running at a fraction of the cost. @googrish and his crew at @castformai do it best.
“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👇
It’s refreshing to witness Silicon Valley come up with something that forces it to reinvent itself and not impose any artificial scarcity on it. Code on tap? Great, double down on it. For comparison Kodak invented the digital camera in the 70s and buried it to protect film sales.
