Mostly wrong · 25%I predict that by July you will have full access to models that are at least as good as Mythos for code analysis.Artificial Intelligence · made May 2026 · due Jul 2026

What happened. Anthropic kept Claude Mythos Preview restricted and announced Claude Mythos for general use on 15 September 2026, about six weeks after the deadline. This pass found no widely available model shown to match Mythos on code analysis by July. Full access to Mythos-class capability arrived, but after the deadline. Whether another model was 'at least as good' by July is arguable, so confidence is low. Sources: anthropic.com.

Wrong · 0%GPT5 is going to be ten times as disruptive and it will likely be released this year.Artificial Intelligence · made Feb 2024 · due Dec 2024

What happened. OpenAI released GPT-5 on 7 August 2025, not in 2024. The release came about eight months after the deadline. Only the release-date part is scored, since 'ten times as disruptive' cannot be measured. Sources: en.wikipedia.org.
