I have read recentley that OpenAI is actively expanding ChatGPT with new ad placements for marketers, enhanced features like auto-attachments for long pastes, and improved memory capabilities. what i noticed is that sponsered ads will appear in the chats, which will pitch its ad business at Cannes, utilizing users' commercial-intent queries to deliver sponsored answers, though ads are strictly barred from health and politics, enhanced long text pasting for free users in order for them to convert pasted text over 10,000 characters into attachments to avoid consuming the context window, a feature already available on Plus/Pro/Business, and  older models like GPT-4.5 and o3 are being officially retired from the ChatGPT interface to direct usage toward newer, frontier models.

Some terms I now understand are LLM, generative AI, memory, AI model, and enterprise AI. One new term I would like to learn more about is agent, because it seems to mean an AI system that can do longer tasks instead of only answering one question.
