List price is not paid price and, as Anthropic has shown, initial list price is going to rise.
Do you have pricing, paid by businesses, plesae provide the contracts that prove you assertion that this pricing holds true, or are we supposed to believe you?
Anthropic have prices they charge for their models. These prices are what you pay if you use the API, and they are also what you pay if you are an "enterprise" customer - generally any company with 150+ employees.
I haven't seen Anthropic raise the prices of an existing model after it has launched. They sometimes raise prices when they ship a model - Fable is $10/$50 where Opus 4.8 is $5/$25.
They also have monthly subscriptions for individuals, which are a notoriously good deal. THOSE are definitely less trustworthy and predictable than the API list prices, since the subscription allowed quotas can and have changed in the past.
Anthropic's enterprise pricing has been thoroughly covered over the last few weeks. I've talked to plenty of people who are paying those prices.
You can chose to trust me or not based on my track record.
From your posting history it looks like you have a whole lot more relevant experience with enterprise software deals than I do. Have you learned anything interesting about how Anthropic pricing works?
To you, if you have specific issues with what I said, I would love to address them, rather than assuming that Simon is always right. Cause let me tell you...
I'm quoting the API list prices for Fable, at it's $10/million input and $50/million output (and $1/million for cache hits on input).
