GPT 5.4 in practice – Stinks?

    We've been testing it extensively and its performance is no better than prior versions, and in many cases worse than open weight models like GLM. Gemini3.1 Pro is so significantly better.

    To me, the play is: open weight on a provider like BaseTen (solid performance, low price point), or pay up for Gemini3.1 Pro if you need it.

    But at their high price and low-ish quality, OpenAI models just aren't in the conversation right now without heavy incentives, e.g. via Azure.

    Crazy, TBH. Curious if others find the same thing?

      I recently tested Claude code, opencode, codex on same frontend feature and codex with 5.4 with high effort was the best but most expensive. For me in Europe, Claude Code with 90$ max subscription is the best value for money.

      My thinking is:

        codex - best harness
  opencode - best ux/dx
  claude - best value for money
