A larger context window means you can paste longer documents, maintain more of a conversation, or work with bigger inputs without the model losing track. Claude currently leads on context length. For tasks involving long documents or extended back-and-forth, this matters more than benchmark scores.
Models without web access are limited to their training cutoff — they cannot tell you what happened last week. Perplexity, Gemini, and the ChatGPT web browsing mode can search the live web. For anything time-sensitive, this is a meaningful distinction.
Conversational assistants are most useful when used iteratively — draft, refine, question, correct. Treating them as a one-shot answer machine undersells what they can do. The quality of output improves significantly when you push back on weak responses and guide the tool toward what you actually need.
