Gemini 2.0 Flash
$180
Cheapest tracked route/tier: OpenRouter
GPT-4o Mini (07-18)
$270
Cheapest tracked route/tier: OpenAI API
Estimated monthly gap: $90.00. 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.
- GPT-4o Mini (07-18) is $0.20/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
- Check replacement coverage for Multimodal, Reasoning, and JSON / Tool use before moving production traffic.
- Provider overlap exists on OpenRouter; start route-level A/B tests there.
- Gemini 2.0 Flash is $0.20/1M tokens lower on cheapest tracked output pricing before cache, batch, or negotiated discounts.
- Gemini 2.0 Flash adds Multimodal, Reasoning, and JSON / Tool use in local capability data.
