Muse Spark 1.1vsGPT-5.6 Sol

GPT-5.6 Sol holds a narrow composite edge (66 vs 59), but the gap is small enough that other factors matter more. GPT-5.6 Sol has the higher Vals/AA intelligence score (73 vs 51). Muse Spark 1.1 is significantly cheaper at $1.3/1M input vs $5.0/1M input. Muse Spark 1.1's 1M context window dwarfs GPT-5.6 Sol's 0 — a meaningful difference for long-document or codebase work.
