What it is in one line
DeepSeek's main conversation site (chat.deepseek.com), one of the highest-traffic AI
products in China: free, ad-free, usable without registration, and the hand that
pushed "open-weights plus a free product" until the whole industry's pricing hit the
floor.
Who built it
DeepSeek, the Chinese AI company with roots in High-Flyer Quant. This slug
maps to the web product, which shares one model family with the mobile app
(slug: deepseek-ai-智能助手); the app is the mobile supplement and the web is the
home of deep use. Famous for open weights, it has been one of China's top AI traffic
products since the R1 release ignited global attention in early 2025.
Read: DeepSeek is the purest "model-company product" — the web product has almost no
product-operations fingerprints. No membership, no campaigns, no community; the whole
budget goes into model capability. Its real competitors are not other apps but the
industry-wide decision of "use the latest open-weights generation or not." Traffic is
a by-product of the model, not of product operations.
What it actually does
- Deep Q&A → the in-house MoE architecture with reasoning, code and math as
strengths; answers carry a full reasoning trace
- Long context → million-token scale; feed it a 40-page research report, a paper,
a codebase
- Web search → optional grounded Q&A replacing the "search first, then
synthesize" routine
- File parsing → an OCR image-text model that reorganizes documents by semantics
- API console → token-metered developer API, long-term among the cheapest
domestic options
- Open-weights distribution → weights are open; developers worldwide
self-host and build on them
What it deliberately does not do: no membership system, no ads, no entertainment
feeds, no mobile-operations spend. The web product is a pure tool — no virality
loops, no retention hooks.
What old behavior it replaces
For ordinary people: the everyday "general search + Q&A" routine.
Looking up a complex answer used to mean opening a search engine, picking from a link
list, clicking in and synthesizing yourself; the DeepSeek web product turns it into
"type it in, get the answer, watch the reasoning." Doubao replaces the same action,
but DeepSeek's answers are closer to "usable as-is" on professional questions.
For developers: it replaces both "running a model locally" and "paying for a
proprietary API." Using a frontier model used to mean either standing up an open
model yourself or paying for ChatGPT's API; DeepSeek's free web product made
"experience frontier reasoning at zero cost" a default action, and open weights made
self-hosting an option. This layer is what actually resets the industry: it moved the
price anchor of "the most capable model" from "expensive" to "free."
Business model
- End users: free, no ads, no paywall anywhere on the web product
- Developers: token-metered API, one of the cheapest domestic options
- Profit center: not disclosed; API and B-end are the presumed channel, with
High-Flyer Quant as the compute base
Read: the web product itself earns nothing directly — it is the brand entry and the
ecosystem hook. The money comes from API and enterprise, and open weights make the
whole world install DeepSeek inside their own products. What makes this model unique:
the free tier is not a crippled version, it is the best version — the single biggest
difference between DeepSeek and every competitor's free tier.

The call
Stable leader, the market is set, but the growth engine shifted gears.
483.8M monthly visits is real and holds the No.1 slot among domestic AI websites.
But the -10.59% MoM, matching the app line's -1.5% (slug: deepseek-ai-智能助手),
shows the whole product line in the post-boom settling period — R1 brought a
pulse-style surge in early 2025, and after the pulse faded, usage returned to a
tool's natural level. That is reversion to normal, not decline.
Its industry shock is done and irreversible: open weights plus free-best-version
moved the price anchor of "most capable model" to the floor permanently. That shock
keeps spreading on the B-end and in the ecosystem — many overseas products embed
DeepSeek weights in their workflows. Judging it by web traffic alone misses the real
measure: penetration inside other people's products.
MoM note: -10.59% is negative but the absolute number is still the domestic No.1.
Compared with Doubao and Kimi, DeepSeek's traffic curve swings harder because its
growth depends on model releases as events, with no daily operations underneath. The
next traffic peak waits for the next "R1 moment."
What to watch next
① Whether monthly visits hold above 400M — continued decline would mean the "deep
Q&A" ceiling is being squeezed further by general-purpose products like Doubao
② Whether the next model release creates another traffic pulse — model events are
DeepSeek's only growth engine
③ New large-scale API/B-end adoption cases — that is the actual commercial base
What you can take from it
Pricing structure: if you have a real technical moat, copy "give away the best
version free" — free is the flagship, not a cripple, destroying competitors' price
anchors while monetizing through API/B-end. This only works if you can stay one step
ahead; otherwise your free tier is just a giveaway.
Product logic: event-driven products (strong launches, weak daily) should accept
violent traffic swings and not patch them with daily operations — you cannot win that
fight. Budgeting for the next highlight moment beats budgeting for growth hacking.
Verdict
Worth watching. The No.1 domestic traffic slot is fact, the pricing shock is
irreversible, but the product line is in a post-pulse settling phase with model
releases as the only growth engine. It is the benchmark sample of a pure
model-company product: winning the whole industry's mindshare by giving away the best
version free, while accepting that general users will not stay.
