GPT 6 Astra cuts hallucination rate from 92% to 51%, claims biggest single-release gain
yanndubs · x · 2026-09-07
A Bridgemind AI post claims the new GPT 6 Astra dropped hallucination from 92% on GPT 5.6 Sol to 51% — billed as the biggest single-release improvement ever — while Anthropic's Fable 5.1 allegedly got smarter but lies more.
Quoting it, Yanndubs cautions that hallucination benchmarks must control for the number of claims a model makes, which neither plot does, so the numbers deserve scrutiny.
