Our note
A long explainer in Japanese uses a shogi theme on a dark green board. Price tags compare 8 and 40 dollars for Fable 5.2 with 4 and 20 for Opus 5.5, shogi pieces stand as bars for model tiers, and five pieces numbered one to five mark the questions of the video. Quoted passages and tables from Anthropic pages, a thinking-depth slider, cost charts, a proof-progress chart and a robot handling objects in a robotics benchmark follow, all with Japanese subtitles. The author says Fable 5.2 wrote the structure, script and visuals, with his own voice synthesized.
Written by The Frontier Brief after watching the video (Nov 10, 2026). It describes what is on screen; we have not run the work ourselves.
