TF-1 Accelerator

TF-1 is Terafab's first-generation AI accelerator, designed in-house and fabricated on a 3nm process specifically to run Grok training and inference workloads more efficiently than off-the-shelf GPUs. It's deployed inside Colossus alongside third-party accelerators, with the group's roadmap shifting more capacity to TF silicon each generation.
