**APIs profiled:** 5

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.
