Company Description

MatX is building an LLM chip called MatX One that delivers much higher throughput than any other chip while achieving the lowest latency. The chip is based on a splittable systolic array, combining the low latency of SRAM-first designs with the long-context support of HBM, resulting in smarter and faster models for users.
