Lines connect measured and explicitly modeled effort points. Filled dots are measured by Artificial Analysis; hollow dots are formula-derived. Snapshot: .

Configurations. AA's Fable point is specifically Claude Fable 5
(Adaptive Reasoning, Max Effort, Opus 4.8 Fallback). OpenAI says max gives GPT-5.6 more
reasoning time than xhigh, while ultra coordinates four agents in parallel by default.
Ultra is a separate multi-agent mode without a directly comparable AA cost/task point, so it is not plotted.
Cost axis is AA Intelligence-Index cost per task, not coding-agent cost. Hollow points are modeled scenarios, not published measurements. To update, edit AA_SNAPSHOT and keep the companion Markdown in sync.
