OpenAI has announced significant improvements to ChatGPT’s search functionality, enhancing factuality, shopping intent detection, and answer formatting to provide more accurate and reliable responses. The update addresses three core areas: reducing hallucinations through better factual accuracy, improving shopping query recognition to show relevant products without overwhelming non-commercial searches, and optimizing response formatting for quicker comprehension without sacrificing detail quality.
However, new research from OpenAI’s own scientists reveals the persistent mathematical inevitability of AI hallucinations, suggesting that while improvements are possible, complete elimination may be structurally impossible. The company’s internal studies show that hallucination rates remain bounded by fundamental limitations in how language models generate text, with errors accumulating across multi-word predictions even when individual word choices are highly accurate.
Critical findings on AI accuracy and limitations:
- ChatGPT Search improvements focus on factuality, shopping intent recognition, and enhanced formatting for better user comprehension
- OpenAI’s mathematical analysis proves hallucination rates are at least twice as high for sentence generation compared to simple yes/no questions
- GPT-5 with web access shows significantly lower hallucination rates, but without internet connectivity, hallucination rates reach 40-47% on factual queries
- The frequency of facts in training data directly correlates with accuracy—rare information faces higher hallucination risks regardless of model sophistication
- Current AI business incentives favor confident responses over uncertainty acknowledgment, creating structural barriers to reducing hallucinations
- Web-enabled ChatGPT performs substantially better than offline versions, making internet connectivity crucial for reliable results
The improvements come as ChatGPT Search processes an estimated 37.5 million queries daily, representing growing competition to traditional search engines. OpenAI’s enhancement strategy focuses on immediate user experience improvements while acknowledging that complete hallucination elimination would require fundamental changes to how language models operate—changes that might make current AI systems significantly less useful for general conversation and creative tasks.
Industry experts suggest that the solution lies not in eliminating hallucinations entirely, but in developing better systems for uncertainty quantification and fact verification, making AI more transparent about confidence levels in its responses.
OpenAI’s search improvements represent meaningful progress in AI reliability, but the persistence of hallucinations underscores the continued need for human verification of AI-generated information in critical applications.
