Limits of any model comparison
The strengths described above are general tendencies, not guarantees. Any of these models can give a confident but wrong answer, and results change as the companies behind them update their models. Treat the table as a place to start and judge by the answers you actually get for your own tasks.
Live search helps with recent events, but it depends on what sources are available and how they are summarised. For breaking news, prices, or anything you will act on, open the original source rather than relying on a summary. For code, run it and test it; for maths, check the working, not only the final number.
How to run your own quick comparison
Because GenAI lets you switch models mid-conversation, you can test them on the work you actually do in a few minutes. Pick one real task, such as a work email, a function you need to write, or a question about this week's news.
Send the identical prompt to each model and compare the replies on accuracy, length, and how much editing they would need. Where the models disagree, that is the part worth checking against a trusted source. After a few rounds you will know which model to reach for first for each kind of task.
