OpenAI has working first-party inference silicon. Jalapeño’s first numbers are strong across three public models. But the clean read is not “OpenAI beat Nvidia.” It is: credible engineering samples, tested on a public suite, with public reproducibility still missing.

OpenAI says its Jalapeño chip can power faster AI responses than the competition
OpenAI still isn’t giving up Nvidia chips, though.
OpenAI’s Jalapeño chip is built for fast inference at scale, benchmarks show | TechCrunch
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 to release open-source model as AI economics force strategic shift
OpenAI plans to release its first open-weight AI model since 2019 as economic pressures mount from competitors like DeepSeek and Meta, marking a significant strategic reversal for the company behind ChatGPT.

6 months to live for open models
The most serious test to date of open source AI’s viability is happening right now.
OpenAI says it plans to stop supplying models to Cursor on Nov. 12 after SpaceX's acquisition. Cursor says OpenAI is about 5% of its traffic. Anthropic says it will increase Claude compute. This is not just another Musk–Altman fight. It tests whether model APIs are actually neutral infrastructure.
