If usage is low or highly volatile, external APIs may remain more cost-effective. Capacity reserves for peak loads affect both scenarios.<\/p>\n \u201cFrom Tokenmaxxing to Valuemaxxing\u201d means this: Measure business value rather than just the number of tokens generated. More meaningful metrics include cost per successfully processed transaction, quality of results, processing time, and the amount of necessary human follow-up work.<\/p>\n | | |
