Tested on SemiAnalysis’ InferenceX benchmark, Jalapeño registered both more tokens per user and more throughput per kilowatt than the currently available state-of-the art.
Jalapeño’s first results show industry-leading speed and efficiency in AI inference
Jalapeño is a custom inference chip from OpenAI that delivers faster, more power-efficient AI inference, with higher throughput and lower latency for modern models.
OpenAI and Broadcom unveil LLM-optimized inference chip
OpenAI and Broadcom introduce Jalapeño, a custom AI chip built for LLM inference to improve performance, efficiency, and scale across AI systems.
OpenAI says its Jalapeño chip can power faster AI responses than the competition
OpenAI still isn’t giving up Nvidia chips, though.

PSA: @OpenAI is putting the Open back in OpenAI and @GroqInc has Day 0 support. 🤗GPT-OSS 20B and 120B, hybrid-reasoning models with built-in browser search and code execution are now live for instant inference.P.S. We've also launched OpenAI Responses API compatibility. pic.twitter.com/CK7StvMSpr— Hatice Ozen (@ozenhati) August 5, 2025
