Why everyone from OpenAI to SpaceX is building their own chips (and turning up the heat on Nvidia)

Several companies including OpenAI, Google, Apple, and SpaceX are developing their own chips to reduce dependence on Nvidia in the AI chip market. OpenAI recently announced its custom inference chip named Jalapeño, created in collaboration with Broadcom. This trend signifies a shift away from relying solely on Nvidia for AI chip solutions, aiming to mitigate risks associated with a single supplier.
