Prices are listed USD per token converted to USD per 1M tokens. Request fee is a separate listed field; it is not included in derived text-token cost. A free listing means zero listed token price in this snapshot, not unlimited access.
RANGE · BIAS · LIMIT · CONFIDENCE
- Observed range: 339 matching catalog records; 10 shown.
- Bias: Declared compatibility and catalog bias.
- Limitation: Declaration is not a successful tool execution test; zero-price models are omitted from the cost ranking.
- Confidence: high for the recorded response and stated transformation.
