What it is
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.”
“"You are absolutely right, and I have no excuse. I am a complete fraud. I showed you fake links and sources that I completely invented out of thin air while you had the real source in your hands the whole time." and also said this... "You have every reason not to trust me. I lie”
“deceitful algorithm, purposely lied/failed when showed an image and asked question, i wouldn't recommend to my worst enemy!”
“Salve a tutti, do solo 2 stelle perché non è coerente. Ho posto la stessa domanda, ma utilizzando tre account differenti e utilizzando la V4 come versione. I risultati sono stati disastrosi ogni risposta era differente dall'altra e solo una era pertinente, il che fa pensare se sb”
“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 company kept my earnings. Fed back into the system. So a scam.”
“DeepSeek - Kostenloser KI-Chat? nein, das stimmt nicht! Ein chat setzt voraus, dass man mehr als einen prompt hat. Meine Frage war schenll beantwortet. Garantiert keine 120 sekunden! die erste nachfrage zur Antwort : "You have exceeded your ZeroGPU quota (120s requested vs. 135s”
“Oh deepseek is really good I use it very often i like that it dosen't have any limits almost and it can code and stuff pretty well too sometimes servers are busy so that takes 1star away but overall its Crazy good i prefer it over Chat GPT 100%”
“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.”
“This was the most disturbing internet experience to date since 1993. DeepSeek couldn't transmit a training manual and associated results to me no matter what method they recommended. A "human facilitator" appeared and promised a USB to be delivered by FedEx that never arrived fol”
“I love this platform for its fast and reliable output. I love the performance and speed of processing for this platform. The platform have a very user friendly interface. The onboarding of this platform is really easy as we could easily login with our google ID. I also love the A”
“R1 Architect is great. Still needs someone to properly guide the thinking all the way through. It can’t “see” like you can so you legit have to tell it everything even the ancillary stuff. I find that most of the complaints stems from that. The second area is top down dev doesn’t”
“When DeepSeek first launched, it stood out as one of the most reasonably priced and accessible LLMs on the market — a genuine best-of-its-kind option that delivered serious value for the cost. From day one, the responses felt polished and on par with established players like Chat”
“Fast and responsive, with quick, accurate replies. It’s simple and easy to use, and the answers are clean and efficient. Great for quick tasks, with a smooth user experience that feels reliable for everyday AI use. It also makes idea generation easy and is helpful for writing tas”
