OpenAI has introduced a memory feature in ChatGPT, enhancing the personalization and accuracy of responses. This feature allows ChatGPT to remember user conversations across different chats, making interactions more seamless and tailored. After nearly six months of anticipation, this feature has finally been rolled out. Similarly, Anthropic's Claude has also integrated a long-term memory feature, positioning itself as a strong competitor to ChatGPT. Claude Sonnet 3.5 now becomes much more useful with the GPT-4o like memory feature. This upgrade in Claude could potentially transform AI interactions in various sectors, including healthcare and education. The advancements in both ChatGPT and Claude are seen as significant steps in the evolution of AI, with potential implications for other AI-driven assistants like Amazon's Alexa and Apple's Siri.
