QuestLoops Verdict

▸ Decision summary

Claude and DeepSeek sit at opposite ends of the AI chatbot price spectrum. Claude is a premium, closed model with strong coding and analysis but a tight free tier, while DeepSeek is a completely free chat app backed by cheap, open-weight models. This compares what each free tier actually gives you and when the price gap is worth paying.

Pick Claude if you need the strongest reasoning and code quality and can live with tight free-tier limits. Pick DeepSeek if you want a genuinely free daily driver and don't mind occasional peak-hour throttling.
