Rumor: Opus 5 May Be Anthropic’s Next Big Move
kimmonismus · x · 2026-07-20
A speculative post argues that Opus 5 is likely the next major move from Anthropic, with pressure on the company rising fast.
The author claims OpenAI has already caught up with GPT-5.6 and strong community efforts, while Chinese open-source models are also closing in on Anthropic’s SOTA tier. They say rumors suggest Opus 5 may outperform Fable 5, but that Anthropic would need to follow up quickly with another Fable 5 release to avoid undercutting its own flagship model. The post ends by saying July could be a very busy month for model launches.
