Unconfirmed

Regarding the release date, initial leaks from accounts like Legit suggested a July 24 launch. Subsequently, users like @markk and @patiencecave relayed rumors of a brief delay to the next day, while @imjustnewatai claimed it could happen within hours. On July 25, @MaziyarPanahi and Reddit user @Over-Necessary-4774 shared alleged UI screenshots showing "Opus 5" in Anthropic's model selector, labeled "For complex tasks" with an "Effort: Max" option. Regarding performance and pricing, information relayed by @mcraddock indicated that Opus 5's benchmark performance is expected to be close to Fable 5; Polymarket-related posts suggested its price might be only half of the latter, and @danielmac8 expected pricing and availability details to be revealed at launch.
