Claude Opus 5

Anthropic's everyday frontier model, released 24 July 2026. It ran all four briefs. The cut-paper garden on Pip & Pocket and the letterpress game dossier on Three in a Row are the two places the illustration work is hardest to ignore; the conference log is quieter and still complete.

Cut-paper garden. Bright cream paper, saturated leaf, sun, sky and clay, every shape outlined in confident ink. Strict grids and tabular figures underneath so the joy never costs the parent clarity.
