Q: How is Pathways different from today’s large models?

A: Instead of training a fresh model per task, Pathways trains one extensible network that can specialize on the fly; unused parts stay dormant, so compute scales with the request, not the total size.

Q: Does Pathways only work inside Google?

A: Public papers describe the architecture, but Google has not released open-source code or outside cloud access, so current use appears limited to internal Google workloads.

Q: What hardware does Pathways target?

A: The design assumes a cluster of TPUs or GPUs connected by high-bandwidth data-center networks; scheduling logic decides which devices activate for each task.
