What is Cerebras used for?

Cerebras is an AI inference and training cloud built on the company's wafer-scale chips, offered as a cloud service and as rack-scale systems. It is a good fit for fast inference for agentic coding tools and running large models on non-GPU hardware.

Is Cerebras open source?

No. Cerebras is proprietary (closed-source) software. Open-source alternatives to Cerebras include SGLang and vLLM.

Can I self-host Cerebras?

Yes. Although Cerebras is closed source, it can be self-hosted on your own servers, and the vendor also offers a hosted version.

What are some alternatives to Cerebras?

Cerebras competes with Groq, SambaNova and Together AI. For open-source options, see Enlisted's ranked list of open-source Cerebras alternatives.

Cerebras: features, pricing and alternatives

About Cerebras

Cerebras designs very large wafer-scale processors for AI and sells them as both cloud services and hardware systems. The company positions itself around fast inference for large models, with its chips replacing clusters of conventional GPUs for those workloads.

Its newest announcement is the CS-4, a rack-scale system intended for deployment at hyperscale. The homepage also highlights fast frontier-model inference running on Cerebras hardware, an inference partnership with AMD that splits work between processors, and customers building coding and software-creation tools on its speed. Performance comparisons are the vendor's own, and the site notes that results vary by workload and configuration.

Cerebras is a proprietary commercial offering with a pricing page, a get-started option for developers and a trust center. It suits organizations that need very fast token generation for agentic applications or want to run large training and inference jobs on non-GPU infrastructure.
