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.

“I've used most of them on the AI front, from the moment they all came out, up until last week. Somehow I missed this one, and it's absolutely blown my mind. It comes out streets ahead of all the others. It's quick, precise and wrote a .php file in seconds where all the others had struggled to get right! ”

“"How the hell CAN DeepSeek charge me $1.7k?????" "Okay so I will be honest before I address this issue , this is my friends acc who is a vibecode dev and I am just helping him out." Something isn't checking out brother. Why don't you ask DeepSeek what happened. I bet it can identify where it went wrong.”

“I've been using that for a few hours in a row. My impression so far speed is unbelievable (4x compared to Terra / Sonnet) - that makes the different. If there's a mistake - correcting it is 10x faster Tried to execute dangerous commands impacting critical OS files outside of repo folders - this is a red flag meaning never let it run in auto mode (but I think this should be a best practice for everyone already) Mostly backend tasks - but in the two UI-related tasks was able to design pretty cool ”

All we know is that, he started using DeepSeek v4 pro starting from 1 October and tdy mrng he woke up to this. No agents were running all night, no big task was set to on seen, he only used it for debugging. Anyone who can help revert this if possible PLEASE COMMENT…”
“I've been using it this morning on my continued llama.cpp performance work, and it's just ripping through the work at amazing speeds. The output flies past and I can barely even skim read it. Then when it stops and waits for my input, even though I type at ~100wpm, I'm feeling like I'm very much the slow link in the chain here. Still, it's helped me to more than halve the non-weight VRAM overheads of qwen4exp, meaning that users can allocate more context, AND use higher ubatch sizes, AND”

“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 ChatGPT and Claude, and the UI matched the clean, intuitive feel users expect from top-tier AI providers. It was responsive, interactive, and easy to slot into daily workflows. Overall Review UI/UX & Integration: The interfa”

“It keeps responding in Chinese. I keep telling it not to, and within a few responses it is back responding in Chinese. I would like to be able to read Mandarin but unfortunately I cannot, so this renders deepseek useless for me as a English language user. Sad as otherwise I think it is a excellent tool.”
