OpenAI has updated its ChatGPT platform, enhancing the Deep Research feature for better accuracy and relevance in reports. Users can now instruct the AI to source information from specific references. The side menu has been redesigned for improved navigation, and a wider range of connected applications has been introduced. The GPT-2.5 model's responses have been refined for better interaction. Last month, OpenAI launched ChatGPT Go, its most affordable subscription tier, utilizing the GPT-5.2 model, offering rapid response times, ten times the messaging capacity, file upload options, and additional features compared to the Free tier. The Deep Research feature, designed to emulate a human analyst, compiles comprehensive reports from online sources, with completion times ranging from five to thirty minutes based on topic complexity. OpenAI's updates come amid competition with Google and its AI tools. Users are advised to verify the accuracy of the information provided.
