The companion to "Jev vs OpenAI Decisions API: I Ran 505 Real Tests (Use This One)" (Oct 7, 2026). PAGE 1 — the two decision APIs on paper (price, images, endpoints, launch dates) and our 505-decision scoreboard: Jev 385 right, OpenAI 378, OpenAI faster, and the real price gap of 1.33× instead of 2.4×. PAGE 2 — ten use cases with the API to pick for each, plus the three rules nobody tells you: the 60% rule, ask yes/no when you need real odds, and call OpenAI directly for images. PAGE 3 — copy-paste request code: both models through the Vercel AI Gateway, OpenAI direct with an image, and the two-judge setup with the 60% rule. PAGE 4 — how we tested and sources. Our own runs on October 7, 2026; OpenAI facts from its Decisions guide and launch post. Independent guide from Hyperautomation Labs — not affiliated with OpenAI or TypeSafe AI.
