Switch friction

GPT-5.2 -> Mixtral 8x7B
  • Provider overlap exists on Replicate API; start route-level A/B tests there.
  • Mixtral 8x7B is $13.55/1M tokens lower on cheapest tracked output pricing before cache, batch, or negotiated discounts.
  • Check replacement coverage for Vision, Multimodal, and Reasoning before moving production traffic.
Mixtral 8x7B -> GPT-5.2
  • Provider overlap exists on Replicate API; start route-level A/B tests there.
  • GPT-5.2 is $13.55/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
  • GPT-5.2 adds Vision, Multimodal, and Reasoning in local capability data.
