Switch friction
- Provider overlap exists on NVIDIA NIM, AWS Bedrock, and Fireworks AI; start route-level A/B tests there.
- Mixtral 8x7B is $0.55/1M tokens lower on cheapest tracked output pricing before cache, batch, or negotiated discounts.
- Check replacement coverage for Vision, Multimodal, and Structured outputs before moving production traffic.
- Provider overlap exists on Microsoft Foundry, Fireworks AI, and NVIDIA NIM; start route-level A/B tests there.
- DeepSeek V3.1 is $0.55/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
- DeepSeek V3.1 adds Vision, Multimodal, and Structured outputs in local capability data.
