DeepSeek

What it does.

DeepSeek combines a consumer conversational assistant with a separate developer model platform. Its official site links the web chat, mobile downloads, API documentation and model research. Treat those as different access routes: a consumer conversation is not an API deployment, and downloadable models have their own operating requirements.

People drafting explanations, exploring technical questions or comparing language-model answers on non-sensitive material.

A direct chat interface and documented API provide distinct entry points for everyday exploration and controlled software experiments.

Rankings measure observed use or spending within their stated samples. They do not establish output quality or suitability for your task.

• Web visits: #5 · edition 7 · 2026-08 · not explicitly stated in supplied chart · source label: DeepSeek · product scope · No volume is supplied. Rank does not measure quality or suitability. Chart says Unique Monthly Visits; article says monthly visits; neither is a count of unique people. · Method and source
• Mobile monthly active users: #14 · edition 7 · 2026-08 · not explicitly stated in supplied chart · source label: DeepSeek · product scope · No volume is supplied. Rank does not measure quality or suitability. · Method and source
