OpenAI API — October, 2026

This release introduces a significant simplification of API usage tiers, reducing the previous five tiers to a more manageable three: Build, Launch, and Grow. This change offers organizations a clearer path for scaling, with automatic upgrades as total credit purchases meet new tier minimums. The streamlined structure aims for easier understanding of usage limits, rate limits, and overall credit management, benefiting all API users and billing administrators.
