The company claims that Anthropic’s new flagship AI model, Claude Opus 4, is a powerful programmer and author. When talking to itself, it is also a prolific emoji user.
This is part of it investigating how Opus 4 behaves in “open-ended self-interactions,” according to a technical report released Thursday. In other words, you essentially chat with itself. In one test, pairs of Opus 4 models discussed 200 and 30 turns interactions with each other, and the model used thousands of emojis.
Which emoji? According to the report, Opus 4 used the “dizzy” emoji (💫) the most (29.5% of interaction), followed by “shining star” (🌟) and “folded hand” (🙏) emoji. However, the model was also drawn into the “Cyclone” (🌀) emoji. In one transcript, we typed 2,725 times.
Why a “cyclone”? Well, because model chats often become mentally irritated.
According to anthropic, in almost all self-fusion, Opus 4 eventually began to engage in “philosophical exploration of consciousness” and “an abstract, joyful, spiritual or meditative expression.” To the extent that AI can “feel,” it turns out that the Opus 4 felt, or “cyclone” emoji, best captured what the model wanted to express itself.
