I've not been impressed with their models. Argon seems good but the usage limits on Pro feel worse than Sol/Astra/Opus on competing plans. But where Luna and Haiku have gotten to point of being 'good enough' for grunt work, I don't feel like 3.8 Flash is there.

That view somewhat biased by Flash getting stuck looping in Antigravity's CLI when I asked if it could add plan usage % to the status line. Instead of "no", it first pretended agy was Claude Code and gave me a wrong answer, then resorted to trying to analyse the binary.

Their harness situation is just awful.
