Anthropic is reportedly putting the final touches on Claude Opus 5, and it could arrive as soon as this week.
According to leaker Leo, the model is in its final preparation stages. It might launch this week or possibly slip to next week. Performance is expected to be close to Fable 5, but with lower operating costs. Anthropic has already extended the subscription period for Fable 5 until July 19, but it doesn’t plan to push the deadline again.
The news was broken by leaker Leo on X:
