DecisionNode: CRAZY Fast Typed AI Decisions... But I Measured 147 ms, NOT 19?!
DecisionNode (by Bynn) is a decision model API: it reads your input once and returns typed answers (choice, score, truth, number, point, box) with a confidence you can branch on. I tested speed, prompt injection, confidence, boosters and the Knowledge booster on my own key, and I show where it did NOT match the marketing page. Try it (my referral link): https://decisionnode.com/?ref=7gfg6bmz $5 off your first top-up SPONSORED: Bynn paid me to make this video. I showed wins and losses. CHAPTERS 0:00 Hook: 16 typed answers, my 147 ms vs their 25 ms 0:53 The problem with chat models for decisions 2:08 decisionnode.com tour and the race 3:47 The model: six answer types and confidence 5:47 Images, points, boxes, video and sessions 7:04 Boosters 8:10 Inference: why it is fast 8:56 Benchmarks: wins and losses 10:29 Examples 11:08 Docs, SDKs, MCP and CLI 11:51 My live tests 16:51 Pricing, free tier, open models 17:51 Verdict WHAT I MEASURED (my own key, free tier then paid credits, about $0.002 total, one location, model version 0.9.1-rc1) - 16 questions on DecisionNode Flash, uncached, 30 runs: server median 147 ms, round trip about 389 ms (site claims 19 ms end to end; its race card uses 25 ms and is labelled mock timings) - DecisionNode (bigger model): server median 592 ms, round trip about 904 ms (site claims 24 ms) - Prompt injection: 25/25 on both models (my 25 tickets, 10 hidden attacks) - Confidence: answers at 0.9 and above were right 38 of 38 on my 30 labelled tickets; one nearly empty ticket still got 0.96 on Flash - Knowledge quiz: 15/15 on both models (a small quiz, not their MMLU-Pro suite) - Receipt, OCR and AI-generated booster, box test (overlap 0.86), Knowledge booster test, one segment booster timeout (kept in the video) Benchmark numbers on decisionnode.com are Bynn's own, preliminary (October 2026). My tests are small and are not a benchmark.
