OpenAI Jalapeño: Better Than Nvidia Blackwell

OpenAI has unveiled "Jalapeño," an inference chip that reportedly outperforms NVIDIA's Blackwell and Vera Rubin. Benchmarking with the InferenceX suite shows Jalapeño's STP output token throughput per MW surpasses Vera Rubin's MTP results and significantly exceeds GB200's 2025 MTP results. While impressive, these results are based on an 8k1k workload, which is easier to optimize, and do not yet include AgentX runs, indicating further optimization is needed for complex, multi-turn agentic workloads.
