This model has no separately published cached-input rate on the provider's rate card, so every input token is priced at $1.250 per 1M regardless of repetition. On repetitive workloads that is a real disadvantage against models that discount cache reads by 90%.

Cutting this bill in practice
If a cheaper model on the table above would work for your task, the blocker is usually integration effort rather than the price difference.
Switch models without rewriting your integration
The savings on this page are only real if you can actually move traffic to the cheaper model. Aggregators and gateways sit in front of multiple providers so that switch is a configuration change.
- AIML API
One API surface in front of 200+ models. The reason it matters for cost: switching model becomes a string change rather than an integration rewrite, so the savings this site calculates are actually reachable instead of theoretical.
Caveat: Adds a middleman margin on top of provider rates — check its per-model pricing against the tables above before assuming it is cheaper. - OpenRouter
Provider-agnostic routing with automatic fallback. Useful when the cheapest model for a workload changes month to month — which, given how often the tables on this site move, it does.
Caveat: Routing does not make any individual model cheaper. It reduces the cost of switching, not the token price.
