H3-Context-IR: The Prompt Compiler

By the end of this lesson you can
  • Create a Context-IR task by POSTing to the correct endpoint, and explain why no task_type parameter exists in any request body
  • Build a valid Context-IR request including the duration and ratio fields most guides omit
  • Read the enhanced prompt's structure and decide when Context-IR beats hand-authoring the grammar from h3-c2

Lesson h3-f1 split H3 into three logical modules: H3-Context-IR for prompt and context understanding, H3-Base for generation, H3-Regenerate-2K for mastering. This lesson is about the first one — the stage that takes whatever you submitted and expands it into the detailed, structured prompt H3-Base actually consumes.

Context-IR is hosted-only. The docs are direct about it: "H3-Context-IR is a complex system and its implementation is not open sourced. This API can be used both to validate the official Full 2K-Workflow results and in production workflows." Even if you self-host the open H3-Base weights (lesson h3-c9), prompt enhancement stays behind this API.
