# 302 AI Workbench > BYOK multi-model AI workbench and reusable 302.AI integration contract. ## Primary resources - [Integration Contract](./ai-contract.md): capability routing, endpoints, context and security rules. - [Integration Manifest](./integration-manifest.json): machine-readable application and endpoint metadata. - [OpenAPI](./openapi.json): compact API surface used by the integration kit. - [Application](./index.html): human-readable workbench UI, live model testing and guided developer integration. ## Important rules Use runtime model discovery. Do not assume GPT, Claude, Gemini or any other specific model is available to every account. Never embed the project owner's API key in a public frontend. For owner-funded production usage, proxy calls through a server or edge function. ## Rendering Assistant responses are stored as raw Markdown and rendered locally. Raw HTML is not executed. Bundled PrismJS provides code highlighting and bundled MathJax SVG provides math rendering.
