Cerebras
Cerebras is a semiconductor company that designs and sells large-scale chips and systems specialized for AI model inference and training. Its flagship product is the CS-4 system, built around a processor that turns an entire wafer into a single chip. Unlike NVIDIA and AMD, which make GPUs, Cerebras takes a different approach, using its own large custom-designed chips to boost inference speed. In August 2026, it was reported that the CS-4 delivered inference speeds up to 30 times faster than GPUs, and around the same time, Cerebras was also reported to have formed a partnership with Lovable related to AI response speed infrastructure.
