A post quoting a leak claims Anthropic Opus 5 could launch on Thursday.
The leak says Anthropic is targeting Thursday for release, with benchmark performance expected to be comparable to Fable 5 but not better. It also frames the model as Anthropic’s answer to GPT-5.6 and Kimi K3.
Because this is still an unverified leak, it should be treated as a rumor rather than an official announcement.
