OpenAI's GPT -5 has landed with a thud despite strong benchmark scores and praise from early testers. Why it matters: A lot rides on every launch of a major new large language model, since training these programs is a massive endeavor that can require months or years and billions of dollars.

Forcing GPT-5 on every user comes with backlash, especially from those who preferred older models. But in OpenAI’s view, consolidating into one model maximizes growth, strengthens the moat, and accelerates global adoption before competitors catch up. If the gamble pays off, GPT-5 could become the first AI tool used by the majority of humanity.
