ChatGPT research preview brings conversational generative AI to a mass audience

Summary

OpenAI launched ChatGPT as a free research preview with multi-turn dialogue, follow-up questions and safety refusals. The GPT-3.5-based system also carried clear limitations around factual errors, wording sensitivity and overlong answers, but its accessible interface became a defining entry point for mainstream generative AI adoption. Capability, benchmark and availability claims are attributed to OpenAI unless independently verified.
