How to choose the right large model for your task Here’s my way of thinking: To determine which large model suits your task, ask yourself which company has easier access to the kind of data your task requires. The gap between mainstream models is no longer that significant — what truly matters is who owns the most relevant data. For example, if my task involves X-related content, then Grok would naturally perform better, because it has easier access to data in that domain for model training. Similarly, if my task revolves around YouTube, then Gemini would likely outperform others.
