- Broadcom's stock surged following the reveal of 'Jalapeño,' a custom AI chip co-developed with OpenAI for LLM inference. This partnership signifies OpenAI's entry into proprietary hardware and highlights Broadcom's role in scaling AI infrastructure. The chip's performance advantages and planned deployment at gigawatt scale with partners like Microsoft starting in 2026 suggest strong future revenue potential for Broadcom and could positively impact the semiconductor and technology sectors.
Investing.com -- Broadcom (NASDAQ: AVGO) shares jumped 3.4% Wednesday morning following the unveiling of "Jalapeño," a custom AI chip developed in partnership with OpenAI.
Billed as OpenAI’s first "Intelligence Processor," the custom accelerator was designed specifically for large language model (LLM) inference and moved from design to production in just nine months. The chip marks OpenAI’s official expansion into proprietary hardware as part of its full-stack infrastructure strategy.
Built from scratch around OpenAI’s specific model requirements, Jalapeño utilizes Broadcom and Celestica for implementation, rack integration, and networking. Engineering samples are already running active machine learning workloads—including OpenAI’s GPT-5.3-Codex-Spark—at production-target frequencies and power levels in the lab.
Early lab testing indicates the architecture delivers a substantial performance-per-watt advantage over current market alternatives by minimizing data movement and optimizing the balance between compute, memory, and networking.
OpenAI plans to deploy the chip at a gigawatt scale across data center partners like Microsoft beginning in 2026. The platform will leverage Broadcom’s Tomahawk networking silicon for its large-scale deployment capabilities.
"Our collaboration with OpenAI represents a fundamental commitment to scaling the physical infrastructure required for the next decade of AI," said Hock Tan, President and CEO of Broadcom. "This is just the beginning of a multi-generation roadmap."
