OpenAI Launches 10x Faster Decisions API with Free Output Tokens

OpenAI has launched a public beta for its new Decisions API, a tool designed to evaluate text and images approximately 10x faster than its standard Responses API. The endpoint currently supports only the gpt-6-luna model, priced aggressively at $0.10 per million input tokens while making all output tokens completely free. Responses are strictly constrained to yes/no probabilities, predefined categorical picks, or scale-based ratings, explicitly targeting document classification and automated customer inquiry routing. The company also consolidated its paid developer tiers from five down to three—Build, Launch, and Grow—with maximum monthly API usage limits scaling from $500 to $200,000 based on credit thresholds.
