   First official capture with a batch price for this model's base (non-fine-tuned) usage. No notBefore: every earlier page that listed the model (2024 'Base models' and 'Older models' tables) had no batch column for any model in that table, and the April 2024 '50% discount' rule covered only the 'Language models' section, so no capture shows it priced without batch. The real start is unknown and may be as early as the Batch API launch (2024-04-15). Fine-tuned-model batch prices are out of scope.
