Claude 3.7 Sonnet
$6,150
Cheapest tracked route/tier: GCP Vertex AI
o1-pro
$270,000
Cheapest tracked route/tier: OpenRouter
Estimated monthly gap: $263,850. Batch, cache, alternate speed tiers, and negotiated pricing are excluded from this local estimate.
Switch friction
- Provider overlap exists on OpenRouter; start route-level A/B tests there.
- o1-pro is $585/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
- Check replacement coverage for Vision, Multimodal, and Reasoning before moving production traffic.
- Provider overlap exists on OpenRouter; start route-level A/B tests there.
- Claude 3.7 Sonnet is $585/1M tokens lower on cheapest tracked output pricing before cache, batch, or negotiated discounts.
- Claude 3.7 Sonnet adds Vision, Multimodal, and Reasoning in local capability data.
