After seeing the last few releases for GPT and Claude, I’m not sure how anyone (else) is gonna build a durable advantage on proprietary model quality.
The capabilities of the top labs’ models have improved so much in just the last few releases, and I definitely foresee a world where they gate those models away behind 1st-party harnesses/tooling.
Across my 4 different gpt subscriptions (personal, personal cursor, GitHub Copilot and cursor) all gpt5 models are junk compared to v4 - constantly ignore prompts, skills, can't write c# or powershell properly the first go, up to 5 tries. Qwen3 hands down beat it on a ryzen 5800 and 6700xt GPU even though it's slow it got the code right first try.
I feel like the v5.0 preview did ok but it's slid all the way down the hill to gpt 2 or 3 levels for me.
Saying gpt 5.4 is like gpt2 is wild.
Lol, audibly.
I'm glad AI curmudgeonry on HN has shifted from "it doesn't work, scam, they made the deployed model worse with 0 communication" to something more akin to "why does anyone use mac or windows, nix is peak personal computing"
