Text Summarization API Quality and Cost Comparison (Per-Tenant Review Rules)

For marketplaces converting code changes into review findings, repeatable tests recording summary quality, schema validity, and spend per tenant are essential. OpenAI, Claude, and Gemini can share an application contract, but the contract must manage evaluations to prevent poor summaries from appearing cheap. Additionally, using tenant-aware batches for processing multiple documents ensures proper accounting records and idempotency. This approach treats support-ticket summarization as a data pipeline, prioritizing usage recording and partial failure visibility over simple endpoint loops.
