Pricing compared
DeepSeek is completely free, including API access, with no mention of usage limits. Claude operates on a freemium model: a free tier with limited usage (likely fewer messages or lower priority) and a Pro subscription for unlimited access and higher priority. Claude's API is also paid. DeepSeek's free pricing is a massive advantage for developers, researchers, or anyone on a budget. However, Claude's paid tier may be justified for professionals who require the large context window and robust features. Users with heavy workloads may face costs with Claude, while DeepSeek remains free.
