Cerebras is an AI platform centered on fast inference and AI training. The site describes it as a system for serving open models, scaling custom models on dedicated capacity, and running on-prem deployments for organizations that need more control over models, data, and infrastructure.
The product pages position Cerebras as a single platform for getting started quickly with an API, then moving into fine-tuning or training when teams need more customization. The company also offers coding-oriented plans and partner access through AWS Marketplace, OpenRouter, Hugging Face, and Vercel.
