“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👇
Jensen Huang is a titan and a teacher. He recently sat down with me to explain his vision of the future of technology and humanity. He’s calm, clear, and very funny. We touched on many topics, ranging from the $20T or more AI economy in five layers to changes in labor for the AI age. Here are some of my main takeaways:
1) The world is moving from retrieval to generation
2) Generation offers intelligence customized to the individual
3) Nvidia is making the "generators" of intelligence
4) We've seen this kind of revolution at least three times before with energy (Generators), Telecommunications (vacuum tubes / transistors?), and now intelligence (GPUs)
5) There is a five-layer cake of participation in this many-many trillion dollar revolution: Energy, Chips, Infra, Models, and Applications.
6) There are many ways to participate in this revolution, and everyone has a role
7) We'll be pushed to dream up new problems to solve with this unprecedented intelligence
8) In this new future, it's not just having the answer, it's having the right questions
8) The right questions will drive us toward our individual and collective human purpose
9) We move from the carpenters to the architects
I believe this is the realistic future. Thanks to Jensen and the entire @nvidia team for the conversation and for letting us share!

A 6-person team is building task-specific AI models that are 4-8x faster than anything from OpenAI or Anthropic. 500K downloads on HuggingFace. No hype. Just better engineering winning on the merits.
This is what "make something people want" looks like in the model layer.

Stop living in a bubble.
The key to happiness, the true meaning of life, is not impact or wealth or fame, but health, friendship, and care for others. Living authentically is not that expensive.
In other words, money or success will not fill the hole in your heart.
