# Build with TypeSafe TypeSafe makes units of AI intelligence usable like programming primitives: small judgments you can compose into larger capabilities. Its **System One models** return fast, focused judgments that software can consume directly. **Jev** is TypeSafe's flagship and first System One model. It understands natural language and returns typed answers and probabilities rather than generating text or reasoning explanations. Code owns the workflow; the model supplies programmable common sense where ordinary code needs semantic understanding. ## Read the live docs **The live TypeSafe docs are the source of truth. Read them as part of the task.** This skill gives direction; the docs carry current concepts, prompting guidance, API contracts, SDK usage, models, limits, and worked examples. - Start with the [documentation index](https://docs.typesafe.ai/llms.txt) to discover relevant pages and cookbooks. Use targeted reads rather than loading the entire site. - Mintlify serves Markdown by appending `.md` to a page path, for example [how to build with TypeSafe](https://docs.typesafe.ai/concepts/how-to-build-with-system-one.md). Follow links from the index; convert extensionless documentation page links to `.md` when useful. Resolve relative links against `https://docs.typesafe.ai`. - Before writing an integration, read the current API or chosen SDK page and the question guidance relevant to the design. For a new workflow, also inspect the closest cookbook:
