Opus 5.5 also identified Breakout for me when I tested it in the Chat on the website.

Can you give some details on what you did?

		I asked Opus 5.5 in Claude Code to prepare a reproduction of one of the things in the article. It created a 130 KB file with the prompt for the task of identifying the game + the weights. I pasted that into Claude on the web and asked it to perform the task without using tools.
