OpenAI is said to be teaming up with Broadcom and TSMC to create custom AI chips.The move would place OpenAI alongside tech giants like Meta, Amazon, and Google who design and build their own chips.OpenAI would gain greater control over its supply chain and benefit from the opportunity to create chips more suited to its needs.By designing chips specifically for its models, the chips should offer more speed and greater energy efficiency.However, although OpenAI has secured manufacturing capacity with TSMC, it has put plans to build its own network of chip factories on hold for now.Custom chip design is typically an exclusive option for the biggest tech companies due to high upfront costs.In designing its own chips, OpenAI will have access to benefits such as diversification of suppliers and lower costs.OpenAI's move would reduce its dependency on market leader Nvidia for AI chips, and incorporate AMD into its supply mix.OpenAI's CEO, Sam Altman, has been outspoken about the need to increase chip supply.The company has deep pockets for the investment, raising $6.6bn from investors in early October 2021.
