Pareto 26.10 or Solar Mini 4: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Pareto 26.10 for a larger context window (1.05M against 524K tokens).
No benchmark has tested both yet. Pareto 26.10 has none yet; Solar Mini 4 on SciCode, AA Intelligence Index and Humanity's Last Exam (Artificial Analysis run). Compare them on price and context instead.

Benchmark by benchmark
Every board either model has a result on, a category to a fold; bars are each result on a 0 to 100 scale. Only one model is measured on each, so no row names a leader.
