What is Cerebras?
Cerebras is an AI infrastructure company that builds the CS-4, a rack-scale system based on its wafer-scale chip, which it says delivers up to 30x faster inference than GPUs. Its inference service lets you serve open and frontier models, including OpenAI's GPT-5.6 Sol in an Ultrafast mode that the site describes as running at up to 750 tokens per second, through a cloud endpoint, dedicated capacity, or on-premises deployment.
Developers can get started through a drop-in OpenAI-compatible API and an API key, with access also offered via AWS Marketplace, OpenRouter, Hugging Face and Vercel. The platform also supports fine-tuning and pre-training on your own data. Customers named on the site use it for agentic coding, multi-step agent workflows, fast research and search answers, and low-latency voice interactions.
