The fact that they put "every model" repeatedly, then don't actually support even close to "most mainstream models", makes me highly doubtful their service will be more honest and forthcoming once I'm signed up.
Yeah, this was my hunch too, which honestly doesn't bode great for the future, but I'm always up to being pleasantly surprised.
Otherwise I think they just meant chinese models not mainstream models.
Like Hy3, Mimo, etc. Also gemini models but not sure if they are mainstream anymore.
Save for GLM 5.3 - coming soon once it percolates through our providers.
That said the current models ain't bad!
