summary: "Tesla plans to produce 1 terawatt of AI chips annually at its Terafab facility in Texas, with Elon Musk estimating total project costs could reach $1 trillion spread across multiple construction phases. The company aims to reduce semiconductor development cycles from one year to one month by co-locating fabrication and testing at a research facility near Gigafactory Texas in Austin. The updated cost projection represents a significant increase from earlier estimates of $16.8 billion."
