$20 per mo (less billed annually)
DeepSeek
Free chat / API from ~$0.14 per million tokens
Claude Pro is the premium choice for writing, analysis, and long documents, with a careful, steerable style, at $20. DeepSeek offers strong, free chat and an extremely cheap API but less polish. Claude wins on output quality; DeepSeek wins on price.
Pick Claude Pro if your work is writing-, analysis-, or document-heavy and you want the best output quality from a careful, steerable assistant.
Pick DeepSeek if you want strong, free AI for everyday reasoning and coding, or the cheapest capable API for building.
Claude Pro and DeepSeek sit at opposite ends of the AI market. Claude, from Anthropic, is repeatedly praised for the quality of its writing, its handling of long documents, and a careful, steerable style that writers and analysts prefer. DeepSeek became popular for offering strong reasoning and coding free in its chat app and at an extremely low API cost.
On price, Claude Pro is $20 a month (cheaper annually), while DeepSeek's consumer chat is free and its API is among the cheapest available. The choice is mostly top-tier output quality (Claude) versus free, capable AI and a cheap API (DeepSeek).
