  • Light usage, 100k in / 50k out per day, vs $1.50
  • Heavy usage, 1M in / 500k out per day, vs $15.00
  • RAG workload, 5M in / 200k out per day, vs $33.60

Light usage, 100k in / 50k out per day: pricing not directly comparable (one or both models are missing public per-token rates). Heavy usage, 1M in / 500k out per day: pricing not directly comparable (one or both models are missing public per-token rates).
