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.
What am I missing here?
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?
I said that my session would cost $12.11 at standard Anthropic prices, based on using AgentsView to calculate cost against tokens used. I further asserted that Anthropic charge enterprise customers those rates.
You kicked off a lengthy thread which I tried to follow but eventually lost track of the point you were making and/or the questions you were asking.
And now you're talking about bias and I don't know where that came from either.
I'll grant that it could be lower if enterprises negotiate bulk discounts, though the stories I've seen suggest that's not happening, for example this one: https://www.theinformation.com/articles/anthropic-changes-pr...
I think higher prices are very unlikely. Do you think I'm wrong about that?
There are a couple of documented ways you could pay more. Anthropic charge 10% extra for "US-only inference" https://platform.claude.com/docs/en/about-claude/pricing#dat... - and you can also pay more for "fast mode", though I don't see a quoted price for Fable for that yet (just prices for Opus): https://platform.claude.com/docs/en/about-claude/pricing#fas...
Being litigious, assumes that I have taken legal action, which I have not, so be better with your words.
