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: 280 matching catalog records; 10 shown.
  • Bias: Context metadata and price selection bias.
  • Limitation: A listed context limit does not prove usable quality, latency, or successful long-document completion.
  • Confidence: high for the recorded response and stated transformation.
