o3 Mini or Perceptron Mk1.5: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick o3 Mini for a larger context window (200K against 37K tokens).
No benchmark has tested both yet. o3 Mini has results on Aider polyglot, SWE-bench Verified and SWE-bench Lite; Perceptron Mk1.5 has none yet. 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.
