I played at least for a couple of hours with Chat GPT4. I am now a subscriber to its Chat GPT Plus services and committed USD 23 per month for this. While I had used Chat GPT 4–5 months back but this version is something else. Scary and exciting at the same time. We were looking for research assistants for some work but seeing Chat GPT4 capabilities we do not need them.I tested its capabilities with a number of tasks ranging from writing codes to creating characters for stories and the responses were mind-blowing.
