GPT-5.4
An older generation kept on the price card at roughly half the flagship rate. Reasonable for workloads already tuned against it.
What that means
A worked example
Per-token pricing is hard to feel. Take a moderately chatty production workload: 100 calls a day, roughly 10,000 tokens in and 2,000 out each time. On GPT-5.4 that comes to about:
$165 / month
Before caching, batching or volume discounts, all of which move this number a long way. Illustrative only.
Strong at
- -Lower cost than the flagship
Typical use
- -Legacy deployments
Same tier
