The AI community is abuzz today with unconfirmed sightings of Anthropic's next-generation Claude models, Sonnet 5 and Opus 4-6, on Google's Vertex AI platform. The models appeared without any official announcement from Anthropic, leading to a wave of speculation and debate across social media.

Early observers noted the presence of the models on Google Cloud, sparking intrigue. Alex Robson, @imalexrobson, shared the discovery, highlighting that the models were "Gated. Not public yet. But very much there."
