GPT 6 Astra finally fixed the hallucination problem.
GPT 5.6 Sol was at 92%. It cancelled every one of my Stripe subscriptions during a migration.
GPT 6 Astra is at 51%. That is the biggest hallucination improvement I have ever seen from any lab in a single release.
And Fable 5.1 went the other way. Anthropic shipped a smarter model that lies more.
The biggest weakness OpenAI models ever had is gone.
