Switch friction

DeepSeek V4 Pro -> Qwen3-Max
  • Provider overlap exists on OpenRouter, Vercel AI Gateway, and Novita AI; start route-level A/B tests there.
  • Qwen3-Max is $3.03/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
  • Check replacement coverage for Reasoning before moving production traffic.
  • Qwen3-Max adds Vision and Multimodal in local capability data.
