What it is

Overview

A free AI chatbot built on DeepSeek's proprietary V4 model, drawing 430 million monthly visits from developers, researchers, and students. Early reviewers describe strong coding assistance and logical reasoning as the primary draws. The model handles complex problem-solving tasks and debugging without requiring payment or account limits that gate usage. Built as a proprietary system rather than a wrapper on existing frontier models.

DeepSeek is a guru in coding especially if you know abit of what you are doing. Excellent guy. Needs clarification and discussion on the topic of discussion to reach its full potential. With context DeepSeek is amazing.

Cette application ne vaut pas ChatGPT mais elle me satisfait . Elle ne sait pas répondre sur des événements en live mais elle le reconnaît. En dehors du live , elle répond correctement. Et elle a l'avantage très appréciable de ne pas limiter les questions tout en étant gratuite

This looks seriously cool. DeepSeek Coder is a game-changer for my workflow. I'm especially impressed by how it handles complex context without losing its mind. The 32K context window is huge—that's going to save so much back-and-forth when I'm debugging or building a big feature

AVOID THIS "ALTENATIVE" TO CHAT-GPT. The Chinese do not have the resources. This is simply cheap. "Server busy." is your constant compagnion. And it does not think this deeply as ChatGPT does. It makes notoriously and massively obvious mistakes and hallucinates without end.
