THE CRUNCH

OpenAI says its AI system, Jalapeño, helped design a custom chip from scratch to tapeout in nine months. The company claims the AI improved performance and reduced the area of key components. This marks a shift from AI optimising individual steps to AI agents handling parts of the workflow itself.

Architect Labs previously claimed an industry-first AI-designed chip, but OpenAI's Jalapeño is the first to offer concrete performance data. OpenAI disclosed that AI-assisted designs improved a BF16 multiplier by 56% and an FP32 accumulator by 10%, while reducing the area of matrix and SIMD units by 10% and 8% respectively. These gains were achieved through AI-driven implementation, design-space exploration, verification loops, and arithmetic-circuit optimisation.

The industry is moving from AI tools that optimise specific stages like placement and routing to agentic systems that can operate multiple tools and execute sequences of engineering tasks with limited human intervention. While companies like Google and Nvidia have used AI for floorplanning and automation for years, OpenAI's Jalapeño demonstrates a more integrated approach where AI participates directly in the design process.
