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 Mistral Medium 3.5 that comes to about:
$90 / month
Before caching, batching or volume discounts, all of which move this number a long way. Illustrative only.
