Character.AI is an American company founded in 2021 by former Google researchers that operates a platform for creating and talking to personality-driven AI characters. Users build characters with a description, greeting and example dialogue, then share them publicly, and the service has grown into one of the most used consumer AI products by session time. Headquartered in Redwood City, California, the company runs its own dialogue-tuned models and has added voice calls, animated avatars and multi-character scenes, alongside age assurance and safety controls for younger users.

Graphcore is a British semiconductor company founded in Bristol in 2016 that designs the Intelligence Processing Unit, a processor architected specifically for machine learning rather than adapted from graphics. Its chips place large amounts of memory directly on the die and expose fine-grained parallelism, an approach aimed at sparse and irregular models that map poorly onto conventional accelerators. The company sells IPU systems and the Poplar software stack to research and enterprise customers, and has operated as a wholly owned subsidiary of SoftBank Group since its acquisition in 2024.

Cerebras Systems is an American computer hardware company founded in 2016 and headquartered in Sunnyvale, California that builds accelerators for artificial intelligence at wafer scale. Instead of assembling clusters from many small chips, it manufactures a single processor the size of an entire silicon wafer, the Wafer Scale Engine, which removes most of the communication overhead in large model training and inference. The company sells CS-series systems to research laboratories and enterprises, operates its own inference cloud known for very high token throughput, and has built large supercomputers with partners including the Gulf technology group G42.
