DeepSeek Chat is DeepSeek's web chat for DeepSeek-V3 and reasoning models, with open-weights releases. Provides free web access to DeepSeek-V3 large language model.
About DeepSeek Chat
DeepSeek Chat is a web chat interface that gives free access to the DeepSeek-V3 large language model and the DeepSeek-R1 reasoning model.
Its distinguishing trait is that it is backed by open-weights model releases, so the same models can be self-deployed locally rather than only used through the hosted chat. Standard chat usage requires no payment.
It fits people who want free access to a capable chat and reasoning model, or who want to run the weights themselves. Weigh the caveats: access is limited to the web platform, with no dedicated mobile or desktop clients; the free tier may hit rate limits or congestion during peak demand; and it operates under Chinese regulatory content policies that restrict certain topics.
Among web chat assistants, DeepSeek Chat stands out for pairing a free hosted interface with open-weights models you can also deploy locally.

Going viral isn't luck — it's a format that earns watch time, run at volume. The founder of nomadtable grew it past a million downloads, solo, by ignoring view counts and chasing one number: how many people keep watching past the first three seconds. Here's that UGC playbook, with his real figures attributed throughout.

Submit your AI tool where people already search for one. Start with a niche AI tool directory (There's An AI For That, Futurepedia, and Vibedonalds for vibe-coded products), add a couple of general startup and SaaS directories, launch on one platform (Product Hunt or a smaller one like Uneed), and post in one community (a relevant subreddit or Show HN). Spread more directory submissions over the following weeks to get your first users.

The expensive mistake in the vibe-coding era isn't building the app — it's building the wrong one. You validate an AI app idea by talking to about eight people in your target market before you build, and listening for the single capability they all wish existed. That's your wedge. Higgsfield's founder did exactly that on the way to a ~$200M run-rate.

Concepts you should know
- Chain of thought
Asking an LLM to spell out intermediate reasoning steps before producing the final answer. Improves accuracy on multi-step problems by ~10-30 percentage points on most reasoning benchmarks.
- DeepSeek R1
DeepSeek's open-weights reasoning model released January 2025. First open model to match OpenAI o1-level reasoning benchmarks. Disrupted the assumption that frontier capabilities require proprietary checkpoints.
- Reasoning token
Tokens spent by a reasoning model (o-series, DeepSeek R1, Claude with extended thinking) on hidden chain-of-thought before the visible answer. Billed separately at the same rate as output tokens. Can be 10-100× the visible-answer length on hard problems.
