GPT Model Trust Study Reveals Surprising Insights into AI Reliability
As technological advancements continue to shape industries and innovation, a significant portion of the global population is willing to harness the potential of emerging technologies for sensitive domains like financial planning and medical guidance.
In a global poll, more than half of the respondents expressed their readiness to embrace emerging technologies for critical domains such as financial planning and medical guidance. This enthusiasm, however, is accompanied by apprehensions concerning the susceptibility of these technologies to issues like hallucinations, disinformation, and bias.
The Rise of Large Language Models (LLMs)
Large language models (LLMs) such as GPT-3.5 and GPT-4 have demonstrated remarkable advancements across various sectors. From chatbots to medical diagnostics, these models have showcased their versatility. However, their increasing prevalence has also given rise to doubts regarding their reliability.
