o4 Mini or Perceptron Mk1: which to pick

Neither model has a coding score yet, so the two cannot be ranked on coding.

Pick o4 Mini for a larger context window (200K against 33K tokens).

No benchmark has tested both yet. o4 Mini has results on Aider polyglot, SWE-bench Verified and SWE-bench Multimodal; Perceptron Mk1 has none yet. Compare them on price and context instead.

Which one for your work

Each card is decided by one number both models carry. Where only one has it, the card says so and makes no call.

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.
