In this keynote, Fireworks AI CEO Lin Qiao will share a data-driven look into how thousands of companies are adopting new open source AI models in 2025 and what’s actually working at scale.

From real-world tradeoffs between fine-tuning, RAG and off-the-shelf performance, to choosing between dozens of open-source options, this talk will cut through the hype with an inside look at real patterns of enterprise AI usage. Which open source models are seeing real traction? How are usage patterns diverging between startups and larger enterprises, and what are emerging use cases?
