OpenAI’s Decisions API speeds side-hustle checks with yes/no answers

OpenAI’s new Decisions API forces AI to answer only yes/no, pick-one, or score-based questions—no vague gray-area responses. Released in October 2026, it runs on gpt-6-luna, costs $0.10 per 1M input tokens (output free), and is 10x faster than the Responses API. Its use cases include photo damage detection, customer inquiry sorting, and document classification, but its real value lies in…

Key points

  • OpenAI’s Decisions API answers only yes/no, pick-one, or score-based questions, cutting response time by 10x
  • Costs $0.10 per 1M input tokens (free output) and uses gpt-6-luna model, launched October 2026
  • Side-hustle creators can speed workflows by replacing vague prompts with binary judgments (e.g., ‘Has this thumbnail text?’)

A creator named Selene (and her AI assistant Nix) explains how overloading AI with open-ended prompts—like ‘evaluate this article on a 10-point scale’—creates bottlenecks. By breaking judgments into binary questions (e.g., ‘Does this thumbnail have garbled Japanese?’), responses become clear and fast, reducing human rework. The API’s low cost aligns with OpenAI’s goal of minimizing per-item judgment costs, a shift from flashy ‘smart AI’ to high-frequency, low-complexity checks. Selene argues that designing prompts to avoid ambiguity—not just upgrading models—is key to unlocking AI’s speed in side hustles.
