OpenAI Claims Its New Chips Can Outperform Nvidia Processors in Tests
OpenAI published the first benchmarks for its custom Jalapeño AI inference chip, claiming it achieves up to 1.9 times the efficiency of Nvidia Blackwell systems. Chip chief Richard Ho previously stated the processor outperformed Nvidia's GB300 in response speed and work completed per unit of power. OpenAI intends to deploy these chips into its infrastructure later this year to decrease its dependency on outside hardware vendors. While these results target Blackwell, the company has not provided data regarding Nvidia's Rubin architecture.

OpenAI Releases Benchmarks for Jalapeño AI Chip
OpenAI published the first benchmarks for its custom Jalapeño AI inference chip, claiming it achieves up to 1.9 times the efficiency of Nvidia Blackwell systems. Chip chief Richard Ho previously stated the processor outperformed Nvidia's GB300 in response speed and work completed per unit of power. OpenAI intends to deploy these chips into its infrastructure later this year to decrease its dependency on outside hardware vendors. While these results target Blackwell, the company has not provided data regarding Nvidia's Rubin architecture.
Why it matters
Custom silicon allows AI developers to optimize hardware for specific model needs rather than relying on general-purpose GPUs. This move signals a shift toward vertical integration among major AI labs to control costs and power consumption.
What is confirmed
- The Jalapeño chip demonstrates up to 1.9 times the efficiency of Nvidia Blackwell systems.
- OpenAI plans to integrate Jalapeño chips into its AI model infrastructure later this year.
Still unconfirmed
- Jalapeño outperforms Nvidia's GB300 in response speed and power efficiency.
- OpenAI intends to use the chips to reduce reliance on external hardware providers.
What to watch next
- OpenAI's release of benchmark data regarding Nvidia Rubin
- The actual deployment of Jalapeño into OpenAI infrastructure

OpenAI Claims Jalapeño Chip Outperforms Nvidia Processors in Tests
OpenAI has unveiled Jalapeño, its first custom-designed AI inference chip, claiming it outperforms Nvidia hardware in speed and power efficiency. According to OpenAI chip chief Richard Ho, the processor led Nvidia's GB300 on a public benchmarking system regarding response speed and the amount of work completed per unit of power. One benchmark indicates Jalapeño delivers up to 1.9 times more performance per watt than Nvidia Blackwell systems. OpenAI plans to integrate these chips into its AI model infrastructure later this year to reduce reliance on external hardware providers.
Why it matters
OpenAI is attempting to build its own computing infrastructure to support the massive scale of its AI models. This move challenges Nvidia, which currently dominates the AI hardware market and recently reported 106% year-on-year revenue growth. The development signals a shift toward vertically integrated AI companies that design their own silicon.
What is confirmed
- OpenAI developed a custom AI inference chip called Jalapeño.
- OpenAI plans to use Jalapeño chips to support its AI models later this year.
- OpenAI chip chief Richard Ho stated Jalapeño outperformed Nvidia's GB300 in tests for power efficiency and response speed.
- CEO Sam Altman described the new chip as fast.
Still unconfirmed
- Jalapeño delivered up to 1.9 times more performance per watt than Nvidia Blackwell systems.
- OpenAI's new chip drew nearly half the power of Nvidia hardware while achieving a benchmark win.
What to watch next
- Actual deployment of Jalapeño chips into OpenAI's production infrastructure
- Third-party verification of the Jalapeño benchmarks
- OpenAI's future procurement volume of Nvidia hardware
