Source facts
OpenAI reports first performance results for Jalapeño, its custom inference chip, using the public InferenceX benchmark across GPT-OSS 120B, DeepSeek R1 670B, and Kimi K2.5 1T. The post says Jalapeño improved throughput per watt and latency across the tested operating range and that OpenAI plans to begin deploying it within its compute infrastructure by the end of 2026.
Analysis
The release is evidence of frontier labs moving toward purpose-built inference silicon and joint optimization of chips, memory, networking, software, and models for interactive and agentic workloads.
Uncertainty/Doubt
All performance comparisons, power measurements, benchmark configuration, and deployment timing are first-party claims; independent reproduction was not completed in this run.
