The author predicts that Anthropic might remove Fable 5 from the Claude subscription after July 12. This move would look bad in the short term because GPT-5.6 performs exceptionally well.
However, they believe Anthropic will release Opus 5 on Tuesday, July 14, surpassing GPT-5.6 in both capability and token efficiency at the exact same price. The author also notes that rumors leaked last week, suggesting the new model "is definitely Opus 5."
