Willison's September 1 post reports his best SVG pelican from any Anthropic model, but the useful datapoint is the price: $3.30 and 13 minutes 54 seconds of wall clock for a single one-shot generation at the Max thinking level. Latent Space's AINews issue on the same launch reports the matching economics from the other side, a 75% cache-read price cut to $0.25/1M tokens but roughly 20% higher per-task cost because Fable 5.1 emits about 1.7x the output tokens.
