OpenAI unveils Jalapeño chip, challenging Nvidia's CUDA moat

By PulseAugur Editorial · [7 sources] ·

OpenAI has announced its new "Jalapeño" chip at the Hot Chips conference, which reportedly outperforms Nvidia's Rubin GPU results in terms of output throughput per megawatt. This new chip, designed with the help of Codex, can also play the game Doom. If production scales successfully, Jalapeño could potentially challenge Nvidia's CUDA dominance and alter OpenAI's reliance on other hardware providers like AMD and Cerebras. AI

IMPACT This new chip could disrupt the AI hardware market, potentially reducing reliance on existing providers and challenging established technologies like CUDA.
