Hey Anybody read this ? It seems rather obvious and low quality, or am I missing something ?

“At OpenAI, we’re working hard to make AI systems more useful and reliable. Even as language models become more capable, one challenge remains stubbornly hard to fully solve: hallucinations. By this we mean instances where a model confidently generates an answer that isn’t true. Our new research paper⁠(opens in a new window) argues that language models hallucinate because standard training and evaluation procedures reward guessing over acknowledging uncertainty. ChatGPT also hallucinates. GPT‑5 has significantly fewer hallucinations especially when reasoning⁠, but they still occur. Hallucinations remain a fundamental challenge for all large language models, but we are working hard to further reduce them.”
