Sonar or ReMM SLERP 13B: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Sonar for a larger context window (127K against 6K tokens).
No benchmark has tested both yet. Sonar has results on LiveCodeBench (Artificial Analysis run), AA Intelligence Index and GPQA Diamond (Artificial Analysis run); ReMM SLERP 13B 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.
