Kimi K2.6
$1,457
Cheapest tracked route/tier: OpenRouter
o3-pro
$36,000
Cheapest tracked route/tier: OpenRouter
Estimated monthly gap: $34,544. Batch, cache, alternate speed tiers, and negotiated pricing are excluded from this local estimate.
Switch friction
- Provider overlap exists on OpenRouter and Vercel AI Gateway; start route-level A/B tests there.
- o3-pro is $76.51/1M tokens higher on cheapest tracked output pricing, so quality gains need to justify the spend.
- o3-pro adds Code execution in local capability data.
- Provider overlap exists on OpenRouter and Vercel AI Gateway; start route-level A/B tests there.
- Kimi K2.6 is $76.51/1M tokens lower on cheapest tracked output pricing before cache, batch, or negotiated discounts.
- Check replacement coverage for Code execution before moving production traffic.
