// MISSION BRIEF

Your Mission

Everything downstream of an LLM wants structure; the LLM emits prose. Output parsers are the checkpoint, and a tester's job is to attack that checkpoint with every malformed payload a model might produce.

Scoring: equal weight per question.

// FIRST CONTACT

Battle teaser

PydanticOutputParser(pydantic_object=Invoice) gives you:

  1. AA database migration for invoices
  2. BFaster model inference
  3. CSchema-validated Invoice objects from model text, raising OutputParserException when the output does not conform
  4. DA guarantee the model always emits valid JSON
Answers, scoring, hints, and the full battle stay sealed.
