Key features	Wafer-Scale Engine: a single large chip built specifically for AI workloads Cloud inference service running on Cerebras hardware, priced per million tokens Independently benchmarked inference speeds ahead of GPU-based providers on several open models CS-3 systems available for on-premises deployment at enterprise scale Supports popular open-weight models including Llama variants	Managed inference across 20+ open models behind one API Agent SDK for building on top of the hosted models Private AI Factory deployments inside a customer boundary Per-token pricing without GPU cluster management Image, text and multimodal generation endpoints
Pros	Benchmarked inference speed is a genuine, independently verified differentiator Per-million-token cloud pricing lowers the barrier versus buying CS-3 hardware outright Strong fit for latency-sensitive production applications	One API across a wide set of open models Removes GPU provisioning and serving-stack maintenance Private deployment path for regulated workloads
Cons	CS-3 hardware itself is a multi-million-dollar purchase, out of reach for most teams Model selection on the cloud service is narrower than general-purpose GPU clouds Newer entrant competing against far larger, more established cloud providers	Region coverage and rate limits need checking for production traffic Agent SDK is newer than the inference product
Company	Cerebras Systems, founded 2015	FlexAI
