In one line

Google shipped 3.7 Flash on August 13 and 3.8 Flash three weeks later at the same price, 2.7 points higher, with audio and video input added. The best score-per-dollar on the whole table. WhichAI still defaults auto-run to gemini-3.6-flash because that free tier is confirmed and this one is not.

Artificial Analysis Intelligence Index, 2026 rebased scale (top models ~ 55-66). Snapshot: September 4, 2026 (BenchLM mirror), retrieved September 8, 2026. Specs and prices come from the OpenRouter public model list on the same date. Models nobody has measured carry no index score at all and never enter a ranking: where an estimate exists it is shown separately and labelled unmeasured. Context, price, modality and release dates come from the public OpenRouter model list (retrieved September 8, 2026) and vendor pages. Missing values are not published or not yet verified - shown as -. Sources are linked inside the app (Model guide and About > Methodology).
