What limits AI today isn’t imagination – it’s the cost of running it at scale.

In this episode of Inference, Ksenia Se sits down with Lin Qiao, co-founder & CEO of Fireworks AI (an inference-first company) and former head of PyTorch at Meta, where she led the rebuild of Meta’s entire AI infrastructure stack.

We talk about:

Why product-market fit can be the beginning of bankruptcy in GenAI

The iceberg problem of hidden GPU costs

Why inference scales with people, not researchers

2025 as the year of AI agents (coding, hiring, SRE, customer service, medical, marketing)

Open vs closed models – and why Chinese labs are setting new precedents

The coming wave of 100× more efficient AI infrastructure

Watch to hear Lin’s vision for inference, alignment, and the future of AI infrastructure.

And – at the end – Lin shares her very personal journey to overcome fears. Watch it!
