In the first wave of the generative AI revolution, startups and enterprises built on top of the best closed-source models available, mostly from OpenAI. The AI customer journey moves from training to inference, and as these first products find PMF, many are hitting a wall on latency and cost.

Fireworks Founder and CEO Lin Qiao led the PyTorch team at Meta that rebuilt the whole stack to meet the complex needs of the world’s largest B2C company. Meta moved PyTorch to its own non-profit foundation in 2022 and Lin started Fireworks with the mission to compress the timeframe of training and inference and democratize access to GenAI beyond the hyperscalers to let a diversity of AI applications thrive.

Lin predicts when open and closed source models will converge and reveals her goal to build simple API access to the totality of knowledge.

Mentioned in this episode:

Pytorch: the leading framework for building deep learning models, originated at Meta and now part of the Linux Foundation umbrella
Caffe2 and ONNX: ML frameworks Meta used that PyTorch eventually replaced
Conservation of complexity: the idea that that every computer application has inherent complexity that cannot be reduced but merely moved between the backend and frontend, originated by Xerox PARC researcher Larry Tesler
Mixture of Experts: a class of transformer models that route requests between different subsets of a model based on use case
Fathom: a product the Fireworks team uses for video conference summarization
LMSYS Chatbot Arena: crowdsourced open platform for LLM evals hosted on Hugging Face
