DeepSeek R1
$155
Cheapest tracked route/tier: Bitdeer AI
Ling-2.6-Flash
$15.50
Cheapest tracked route/tier: OpenRouter
Estimated monthly gap: $140. 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.
- Ling-2.6-Flash is $0.27/1M tokens lower on cheapest tracked output pricing before cache, batch, or negotiated discounts.
- Check replacement coverage for Reasoning and Code execution before moving production traffic.
- Ling-2.6-Flash adds JSON / Tool use in local capability data.
- Provider overlap exists on OpenRouter; start route-level A/B tests there.
- DeepSeek R1 is $0.27/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
- Check replacement coverage for JSON / Tool use before moving production traffic.
- DeepSeek R1 adds Reasoning and Code execution in local capability data.
