Cerebras Systems

Cerebras Systems builds the Wafer-Scale Engine (WSE) — the largest computer chip ever made — and the CS-3 systems built around it, delivering AI training and inference at speeds far beyond conventional GPUs. Cerebras Inference is the company's cloud API: an OpenAI-compatible REST interface at api.cerebras.ai that serves open-weight frontier models (OpenAI GPT-OSS, Gemma 4, Z.ai GLM 4.7) at industry-leading tokens-per-second. Developers authenticate with a bearer API key and call chat/completions, completions, and models endpoints, with streaming, tool calling, structured outputs, vision, prompt caching, and batch inference. Custom model weights can be deployed on dedicated endpoints. Official Python and Node.js SDKs, a Cloud Console with a playground, and coding-tool integrations (VS Code, Cline, Kilo Code, OpenCode) round out the developer surface.

Cerebras Systems publishes 5 APIs on the APIs.io network, including Chat API, Completions API, Models API, and 2 more. Tagged areas include Company, AI Infrastructure, Artificial Intelligence, Machine Learning, and Inference.

Cerebras Systems’ developer surface includes status page, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 38 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cerebras-systems: open an issue to ask a question, or submit a pull request to add artifacts.
