$1,000
Cheapest tracked route/tier: OpenRouter
Estimated monthly gap: $2,500. 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.
- GLM-5 is $7.92/1M tokens lower on cheapest tracked output pricing before cache, batch, or negotiated discounts.
- Check replacement coverage for Vision and Multimodal before moving production traffic.
- GLM-5 adds Reasoning and JSON / Tool use in local capability data.
- Provider overlap exists on OpenRouter; start route-level A/B tests there.
- Gemini 2.5 Pro Preview 05-06 is $7.92/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
- Check replacement coverage for Reasoning and JSON / Tool use before moving production traffic.
- Gemini 2.5 Pro Preview 05-06 adds Vision and Multimodal in local capability data.
