LLM Model Card Diff

Compare supplied source documents or current authoritative metadata. Do not fill missing fields from memory.

Workflow

1. Record source URL/document, publication date, model ID, version, and provider for each card.
2. Normalize terminology without erasing uncertainty or provider-specific meaning.
3. Compare context, modalities, tools, structured output, reasoning, knowledge cutoff, pricing, limits, regions, safety, training data claims, license, and acceptable use.
4. Classify changes as breaking, behavior-changing, operational, commercial, governance, or informational.
5. Map every material change to affected application contracts and tests.
6. Highlight fields removed, weakened, newly ambiguous, or contradicted across documents.

Output

Return a side-by-side table, impact-ranked changes, unknowns, migration implications, and required tests. Cite document locations when available and never present absence of disclosure as proof of absence.
