GLM 4.6V or Sonar Deep Research: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick GLM 4.6V for output tokens 8.9x cheaper ($0.90 vs $8.00 per million) and a larger context window (131K against 128K tokens).
No benchmark has tested both yet. GLM 4.6V has results on LiveCodeBench (Artificial Analysis run), Terminal-Bench Hard (Artificial Analysis run) and LMArena Text: coding; Sonar Deep Research 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.
