Try both
Specs don't say which model handles your work better. Send the same requests to both and compare the answers, the tokens and the bill. On Zurelay that's a change of model name.

Yes. One Zurelay key calls both. With an OpenAI SDK, point it at https://api.zurelay.com/v1 and change only the model name, claude-fable-5-2 or claude-opus-5-5, to switch.
Yes. Each model is served over several routes run by independent sellers, and every route is tested before it serves requests and every day after, with identity, dated-knowledge and reasoning checks that catch an older or different model sold under the name you asked for.
Create a key in seconds, point the SDK you already use at Zurelay, and every request costs up to 90% less from the first token.
