    Batch from launch (the launch post and changelog name the Batch API). The rates are derived from the pricing page's rule 'Save 50% on inputs and outputs with the Batch API', printed under the section listing GPT-4.5 (first capture listing GPT-4.5: 2025-03-03). No page lists GPT-4.5 batch prices as numbers; the model was retired before the 2025-12-11 docs Batch table. No batch cached-input price.
