OpenAI reveals its first AI processor: Jalapeño
Why it matters
OpenAI is moving vertically into custom silicon for inference, reducing dependence on NVIDIA and Broadcom while optimizing for its own model workloads. This signals a structural shift: frontier labs are now competing on silicon, not just models.
Key signals
- OpenAI reveals Jalapeño — custom ASIC for AI inference
- Partnership with Broadcom on design and manufacturing
- Nine-month timeline from partnership to announcement
- ASIC designed specifically for inference (not training)
- Targets power efficiency for LLM inference at scale
The hook
OpenAI just built its own chip. Jalapeño is an inference ASIC — a nine-month sprint from partnership announcement to silicon.
OpenAI has just revealed a new "intelligence processor" chip for AI servers made in partnership with Broadcom. The chip, called Jalapeño, is designed to power current and future large language models, according to an announcement on Wednesday.
Jalapeño is an ASIC (Application-Specific Integrated Circuit), meaning it's designed for a specific purpose: AI inference. With AI inference, models process a user's request to run an agent like Codex or offer a response from ChatGPT, while AI training involves a model consuming vast amounts of data to inform its responses.
It comes just nine months after OpenAI revealed that it would team up with Br …
