testingcatalog · x · 2026-08-26
OpenAI has released initial performance results for its in-house inference chip, Jalapeño. Benchmarks on InferenceX across three public models show:
- 1.5–1.9× more AI work per watt
- 1.7–3.6× lower end-to-end latency
- 2.1–4.1× higher performance on highly interactive workloads
The project is led by Richard's team. The author, the team's first strategic finance partner, expressed pride in the achievement.
