- Correction: Corrected the stale lifecycle status (Opus 4.1 was deprecated on June 5, 2026 and retired from the Claude API on August 5, 2026, with claude-opus-4-8 as replacement) and Opus 4.7 shown as "current"; fixed a false "second shortest interval" claim, a wrong GPT-5 GPQA Diamond figure (85.7%, not 87.0%), a misdescribed end-conversation feature, a misreading of the tau-bench step-limit note, an invented Hacker News summary and a misattributed TechRepublic argument, and replaced miscited revenue figures with Anthropic's own numbers (plus 33 minor fixes)
