How To Build Generative AI Models Like OpenAI's Sora

If you read articles about companies like OpenAI and Anthropic training foundation models, it would be natural to assume that if you don’t have a billion dollars or the resources of a large company, you can’t train your own foundational models. But the opposite is true. In this episode of the Lightcone Podcast, we discuss the strategies to build a foundational model from scratch in less than 3 months with examples of YC companies doing just that. We also get an exclusive look at Open AI's Sora!
