In a post on X, user alliekmiller reports that Anthropic's Claude Opus 5.5 has become the first AI model to pass their 'code-meets-poetry' challenge, marking a shift from their previous preference for OpenAI models in ideation, creation, and exploration tasks. The user describes testing Opus 5.5 for slide design, where it generated six PNG versions using OpenAI's image 2.5, labeled them, saved them, opened Finder, and messaged its preference. When the user indicated two preferences, the model autonomously created editable PowerPoint slides with text boxes and shapes. The user notes that earlier tool call failures in Opus 5.5 appear to have been fixed, and characterizes the model as a 'tool-wielding machine' that feels far more creative than previous Claude models.
Source report
For the last several years, I have said that OpenAI models are better at ideation, creation, and exploration. If I had to brainstorm something, I would have picked whatever OpenAI model was best in class.
Yesterday, that changed.
Key Breakthroughs
1. Code-Meets-Poetry Challenge
Opus 5.5 is the only model to hit (note: hit, not beat) my code-meets-poetry challenge. It is the only time I have shared the test with a lab. I was in shock.
2. Slide Design Demonstration
Last night when making slides, I prompted both Codex and Claude Code to give me design options for one slide I couldn't crack.
- Codex was a mess.
- Claude Opus 5.5 made 6 versions as PNGs using Image 2.5 from OAI, labeled them perfectly, saved to computer, opened up Finder, and messaged its preference. (I agreed with one of its recommendations but not the other.)
When I said my two preferences, it immediately created them as editable slides in PPT (text boxes, shapes, the whole thing). I did not ask for that.
Reliability Improvements
In my early testing of Opus 5.5, it had several tool call failures. It seems they have fixed that.
Overall Assessment
Opus 5.5 is a tool-wielding machine and feels far more creative than previous Claude models.
