Sir, Dorri1 and Rai2 et al. mentioned generative AI. However, new technologies are frequently presented to us without any instruction or educational structure for their appropriate use.3 There are three generative AI systems via web browser that are free of charge.

The followings are three access links:

Free ChatGPT is based on ChatGPT-3, which is not trained as well as the latest ChatGPT-4. ChatGPT-4 was trained until October 2021 and free ChatGPT-4 is available at Microsoft's Bing.com via Edge browser. Due to the use of pseudorandom numbers in generative AI, users should choose the 'more precise' mode when having a conversation with Bing.com with ChatGPT-4. Even with the more precise mode, the same query may not produce the same solution or answer. Google's Bard will generate several drafts to accommodate the randomness to be chosen by users.

Generally, users need three skills when interacting with generative AI: language skills to use the right words and phrases to identify the goal and subgoals; verification skills to (re)examine the generated solutions and validate them; and design skills to navigate the generative AI towards the goal. To avoid errors and incorrect solutions or answers from generative AI, users must have these skills to reduce unnecessary conversations.

Users are allowed to use search options including site command such as 'site:nih.gov', phrase command such as 'red tape', date command such as 'after:2019-4-30' or 'before: 2024', other commands with Bing.com. Users must be aware that generative AI may provide incorrect information due to a lack of training on certain subjects.
