The real question I see nobody asking is how GPT-5.4 beats Opus at a fraction of the price. I doubt it’s only a question of subsidization. My impression from the past is that GPT-5 was around a Sonnet-sized model, and 5-mini was Haiku-sized. At least on my codebase anyways, Codex one-shots tricky things that Opus needs several tries to fully get right.
IMO it doesn’t handily beat it.
It’s typically equivalent, sometimes better, sometimes behind. Better at following a well defined plan, less good at concept exploration and planning imo.
At 1m context it’s basically the same price.
I wanted to choose Anthropic because they were apparently more ethical compared to OpenAI, but... Yeah.
Right now the only blocker for me is the lack of Linux support.
Cursor?
