Yeah, I have been loving GPT 5.2/3 once I figured out how to change to High reasoning in OpenCode.
It has been crushing every request that would have gone to Opus at a fraction of the cost considering the massively increased quota of the cheap Codex plan with official OpenCode support.
I just roll my eyes now whenever I see HN comments defending Anthropic and suggesting OpenCode users are being petulant TOS-violating children asking for the moon.
Like, why would I be voluntarily subjected to worse, more expensive and locked down plan from Anthropic that has become more enshittified every month since I originally subscribed given Codex exists and is just as good?
It won't last forever I'm sure but for now Codex is ridiculously good value without OpenAI crudely trying to enforce vendor lock-in. I hate so much about this absurd AI/VC era in tech but aggressive competition is still a big bright spot.
I like using Codex inside OpenCode, but frankly most times I just use it inside Codex itself because O.Ai has clearly made major improvements to it in the last 3 months -- performance and stability -- instead of mucking around trying to vibe code a buggy "game loop" in React on a VT100 terminal.
