Cerebras Systems, now a $60 billion public company, nearly failed in 2019 after burning $200 million trying to solve a unique technical challenge: creating a single giant AI chip from an entire silicon wafer. The company’s founders believed this approach would outperform traditional multi-chip setups but faced unprecedented engineering hurdles, especially in cooling and data packaging. After years of trial and error, they succeeded in 2019, enabling partnerships with major AI players like OpenAI, which loaned Cerebras $1 billion. This breakthrough positions Cerebras as a key player in AI hardware, with cautious growth plans focused on select customers before expanding further.
