⚠ The two sources disagree on price
models.dev says $4.2929, LiteLLM says $5. We do not average or guess — both raw values are in models.json, see for yourself.
Prices are official/data-source rates (per 1M tokens), not what relays actually charge — relay prices vary with discounts and group multipliers. See methodology.
