OpenAI announced benchmark results for its custom inference chip Jalapeño, showing 1.5–1.9× better efficiency and 1.7–3.6× lower latency compared to NVIDIA GB200/GB300. Deployment starts by year-end with Gen 2 and Gen 3 in development. The chip runs at 700W but stayed below 550W in tests. Model-assisted kernel optimization using GPT-Astra + Codex improved performance by 1.5–1.8×. This signals a shift in inference stack economics, potentially reducing NVIDIA's dominance. Additionally, research on agent harnesses like AutoSaddler shows system-level improvements can surpass model changes, with significant gains on benchmarks like GAIA2 and SWE-Bench Pro. A new Harness Card standard is proposed to disclose harness variance, highlighting the importance of software engineering in AI agent performance.
