How can it be legal to charge a higher fee for the Fable model, if most of the usage will default to a cheaper model behind the scenes? It is one thing if I, as the user, choose to down-level but Claude shouldn't do this on its own.

They are transparent. Don’t use it if you don’t want to. These things shouldn’t be illegal.

  I agree that it shouldn't be outright illegal, but I will definitely be making the personal choice not to engage with model providers which do this. There's no amount of impressive results that could make me want to secretly pay more for less.

Originally at least the switch wasn't silent and whether to halt or auto switch was a setting in Claude Code.

because it's all indistinguishable from magic when it's a cloud SaaS. Not like you can tell the difference if you dont own any of the implementation.

Judging from their site, I think it should be OK: "You won't be charged Fable prices for rerouted requests. Learn more about how the fallback experience works." https://www.anthropic.com/claude/fable https://www.anthropic.com/claude/fable Under "Safeguards"

  And what happens if you also get blocked by Opus? I couldn't find if they refund the tokens for that session or the customer is SOL.

    You're paying in full for the "guardrails" embedded in the system prompt, prompt injections, refusals, fallbacks and everything else that may be caused by the service provider. This is the new normal.

  This has no mention of what happens to the prompt cache, including the "learn more" link. Knowing Anthropic, it wouldn't surprise me if it will result in a full cache miss/rewrite at fallback, with potentially up to 1M tokens in the context window.

Using only Fable, if I do /usage it will show both Fable and Opus usage, so I don't think it's charging Fable prices for Opus code gen.
