    Type in the box below to try DeepSeek without an account. This independent demo runs DeepSeek V3.1 on free community routes (falling back to R1 when a route is busy), so answers and speed can vary. It does not run V4-Flash or V4-Pro. For the current V4-Pro and V4-Flash models, use the official DeepSeek chat (see our login guide).
