Custom silicon, fabricated for the compute the group needs.
Terafab AI designs and fabricates custom AI accelerator chips purpose-built for training and inference workloads across the group, reducing dependence on third-party silicon and giving xAI, Tesla, and Optimus a hardware roadmap tuned to their own model architectures rather than general-purpose GPUs.
Founded to design and fabricate custom AI accelerator silicon tuned specifically to the group's own model architectures, reducing dependence on third-party chips.
The first-generation accelerator began shipping into Colossus alongside third-party hardware, with the roadmap shifting more capacity to TF silicon each generation.
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.
