OverallGPT runs the same prompt through several models and shows the answers side by side. That is a narrow function with a genuine use: model choice is now a real decision, and the only reliable way to make it is on your own prompts rather than on published benchmarks.
Benchmarks measure aggregate performance on standardised tasks, which frequently fails to predict which model handles your specific work best. Seeing three answers to your actual question, in parallel, answers that directly, and it also exposes where models disagree, which is a useful signal that a question is genuinely ambiguous or that the answer needs verification.
It is a comparison and evaluation tool rather than a working assistant, so it complements whichever model you settle on rather than replacing it. Most valuable during the decision, or when a task matters enough to check one model's answer against another's.
