Sonar Deep Research or Reka Edge: which to pick
Neither model has a coding score yet, so the two cannot be ranked on coding.
Pick Sonar Deep Research for a larger context window (128K against 16K tokens).
No benchmark has tested either model yet, so price and context are the only way to compare them.

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.
What each workload costs
Three fixed token mixes at each model's listed price, so per-token rates become a bill.
