Methodology & confidence
GPT-5: Model facts are curated from public documentation (developer, family, type, documented context window, modalities, capabilities, API availability); SDK-ecosystem signals are live from the official GitHub org. Benchmark scores and live pricing are intentionally not asserted — they are volatile and provider-specific, so they are shown as collecting with a link to official sources rather than estimated.

Only fields that both entities expose are compared. Unavailable fields are shown as collecting — never estimated to force a comparison.
