Amazon Principal Scientist Ido Rosen: Unit Economics First, Open Weights Only Months Behind
arena · x · 2026-10-30
Arena's new Conversations episode features Ido Rosen, Senior Principal Scientist at Amazon, in a discussion with Peter Gostev about the practical side of deploying AI:
- Unit economics first: cost per call versus value should drive deployment decisions before chasing benchmark gains
- A decade in quant trading: Rosen explains how evaluation discipline from high-frequency trading translates into AI evaluation practice
- Pricing pressure from open weights: with open-weight models only months behind frontier labs, closed-model pricing strategy faces real squeeze
The takeaway: moving beyond benchmarks to production-grade, at-scale, budget-conscious deployment is the real challenge.
