Cerebras is an AI inference platform built on wafer-scale chips, offering developers and enterprises high-speed LLM inference, fine-tuning, and training via an OpenAI-compatible API.
About
Cerebras is an AI compute company that provides fast large language model inference through hardware built around its Wafer-Scale Engine, a chip far larger than a standard GPU. Its CS-4 rack-scale system is designed to deliver inference speeds the company states can reach up to 30 times faster than GPU-based systems, making it suitable for latency-sensitive applications such as coding assistants, autonomous agents, and real-time voice conversations.
The Cerebras platform, Cerebras Inference, lets developers serve open and frontier models through an API that is compatible with the OpenAI API format, so existing applications can often switch over with minimal code changes. Based in Sunnyvale, California, Cerebras also offers fine-tuning and pre-training on the same platform, along with cloud, dedicated, and on-premise deployment options. OpenAI's GPT-5.6 Sol is available in an Ultrafast mode on Cerebras at up to 750 tokens per second, and the company partners with organizations including AMD, Lovable, and Meta.

- Free trial and promotional credit: Developers can add a payment method to receive a one-time $5 promotional credit, which expires 30 days after activation and is intended for development and experimentation rather than production use.
- Production-grade availability: The platform is used by cloud service providers and enterprises, with dedicated and on-premise options available by agreement.
Who It's For
Cerebras is aimed at AI application developers, ML engineers, and enterprise platform teams building latency-sensitive products. Typical use cases include coding copilots that need instant responses, multi-step AI agents that cannot afford timeouts, deep-search and analysis tools requiring sub-second reasoning, and voice assistants that depend on immediate answers. Organizations in healthcare, pharmaceuticals, and financial research, including customers like Mayo Clinic, GSK, and AlphaSense, use the platform for applications such as research agents and clinical decision support. Companies needing in-region deployment for compliance can use dedicated or on-premise options.
