Ghostcli Avaliações 

I bought a plan on ghostcli.cloud just to test it out, but none of the models offered on the site are real. I am 100% sure they are running cheap, open source models in the background. When I contacted support with proof and requested a refund, they just replied mocking me.
Their "Opus 5.5" model which supposedly works wonders in a single prompt—doesn't even come close to the real Sonnet 5.5. It's clear that this service is run by a bunch of amateurs who don't take anything seriously. If you are reading this before buying, do not waste your money. They are scammers.

The API works, but that’s about the only positive. I seriously doubt the advertised model is Opus 5.5, and the token counter shows usage figures I don’t trust.
The seven-day refund policy is worthless for testing the service: use any tokens and you’re no longer eligible.
Incomplete translations and a rushed, unfinished website only add to the distrust. Big promises, little transparency. I regret paying and wouldn’t recommend it.

The API key works, but, it's not Claude for sure, but that's about it. I'm getting WAY better results with DeepSeek V4.1 Flash and Minimax 3.1 Flash than with what they are calling Opus 5.5. It's acting more like Haiku 3.5 to be honest.

And this is form the first prompt, not after hitting the endpoint relentlessly. So it's a straight up scam
