Bijan Bowen tests Opus 5 on a browser-style operating system, a C++ skateboarding game, a reconstructed television set, a product site, a first-person subway game and an interactive city timeline. The tasks emphasize complex visual output rather than short benchmark answers.
The model's strongest results come from textures, spatial detail and sustained iteration. Several projects feel more complete than typical one-shot generations, and Opus 5 often keeps refining the implementation instead of stopping at a superficial mock-up.
The review also finds uneven execution. Some requested hero elements or pedestrians never appear, and the model can take a long time to finish ambitious builds. The practical conclusion is that Opus 5 raises the visual ceiling, but its output still needs direct inspection and testing.
