Animated transition from AA Intelligence Index v4.1 to v4.3

An animated transition compares AA's Intelligence Index v4.1 and v4.3, with data sampled on September 3rd and 14th. The update, following Astra's release, shows GPT-6 Astra's intelligence and cost improving significantly. GPT-5.6 Sol also became cheaper, and GPT-5.6 Luna received a substantial uplift. Fable-5.1's price gap from Opus 5 shrank, making it more appealing, while Sonnet 5 became more expensive without intelligence gains. GLM and Muse Spark remained stable, but Kimi-K3, Qwen3.8-Max, Gemini-3.8, and Grok 4.6 saw declines.

This report uniquely provides a direct before-and-after comparison of AA's Intelligence Index versions 4.1 and 4.3, unlike other analyses that only present the updated index.
