DeepSeek is a chat assistant and developer API for generating text, solving problems, and writing code. If you need to turn rough notes into a draft, DeepSeek gives you a starting point.
Use the free chat for low-stakes work, but skip paid API use unless you need it in an app. At $0 for chat, it is cheaper than ChatGPT, with fewer ways to work.
Who it's for
DeepSeek suits you if you can edit drafts and want a cheap text model in your own workflow. You may be disappointed if you need dependable answers, persistent memory, or client-ready work without checking it.
Buy it if
- You write first drafts for blog posts, product descriptions, or internal notes and edit them before publishing.
- You already use an API-based automation and need a text model behind a form, bot, or script.
- You work mainly in English or Chinese and can verify facts before sending work to a client.
Skip it if
- You need cited research that clearly shows which source supports each claim.
- You manage client work where a missed bug, wrong answer, or failed response creates a costly delay.
- You want voice chat, image work, or long-term memory across conversations.
Your first hour
For API use, you need an account and an API key. DeepSeek does not clearly publish the full sign-up flow, card requirement, or waitlist details; its web chat can give you a first draft in your first session.
- Open web chat The consumer web chat is free, although DeepSeek publishes no fixed usage quota.
- Try one draft Paste a real brief and ask for a short output you can check line by line.
- Create API key API access requires an account and key; new developer accounts are reported to receive 5 million tokens for 30 days.
- Check the limits Both listed API models support 1 million tokens of context and up to 384K output tokens.
The chat is simple, but API use is not a non-developer setup. If you cannot send API requests or use an existing connector, stop after the free chat.
What you actually get per plan
DeepSeek chat is free for individuals, with rate limits during busy periods. The API has no monthly minimum or seat fee, so most solo users will stay on free chat; developers pay only for tokens used.
| Plan | Price | What’s inside | Catch |
|---|---|---|---|
| deepseek-v4-flash | Pay as you go, per 1M tokens | 1M-token context, 384K maximum output, 2,500 concurrent requests | Peak input is $0.44 and output is $1.32; off-peak input is $0.22 and output is $0.66. |
| deepseek-v4-pro | Pay as you go, per 1M tokens | 1M-token context, 384K maximum output, 500 concurrent requests | Peak input is $1.32 and output is $3.96; off-peak input is $0.66 and output is $1.98. |
The free chat has no published hard quota, but traffic-based rate limiting can reduce access when demand is high.
Three real situations
These are the practical outcomes when the price and workflow meet real work.
A freelance writer with three retainer clients
They can use free chat for outlines and rewrites at $0. They still need to fact-check every claim and reshape generic prose before delivery.
A solo founder preparing a product launch
They can connect the API to a small internal tool without a monthly seat charge. Flash peak output costs $1.32 per 1 million tokens, but the founder must build the connection.
A two-person online store answering customer questions
DeepSeek is not the right buy for unattended support replies, because incorrect answers can reach customers. The simpler route is to keep approved answers in the store’s existing help centre and reply from those.
Where it falls short
Reviewers report slower replies than ChatGPT, failed responses, and multi-minute waits in DeepThink mode. They also describe DeepSeek as prone to hallucination, even saying it can “hallucinate like crazy” when uncertain. Compared with ChatGPT, it lacks persistent memory, voice chat, image display, image generation, and richer sharing and research tools.
The API price changes by peak and off-peak hours, which makes costs less predictable for scheduled workloads. The privacy policy allows use of personal data to improve models, though you can opt out; this matters if you handle client, financial, or personal information. Support is available by email, but published service guarantees are not apparent.
Watch out: DeepSeek says user inputs may be used to train or improve models unless you opt out of that processing. Do not paste confidential client material before changing the relevant privacy setting.
Common questions
Is there a free plan?
DeepSeek web chat and its mobile apps are free for individual users. There is no published fixed chat quota, but access can be rate-limited during heavy traffic.
What is the cheapest way to try DeepSeek?
Use the free web chat first. For API testing, new developer accounts are reported to receive a 5 million-token grant valid for 30 days.
Can I cancel DeepSeek any time?
There is no API subscription to cancel because API billing is pay as you go. You can stop using the service and can delete your account under DeepSeek’s terms.
Does DeepSeek train on my data?
Its privacy policy says personal data may be used to improve and develop services, including models. You can opt out of using personal data for model training or technology optimisation.
Can I get a refund on unused API credit?
You must contact DeepSeek with supporting materials. If approved, remaining unspent funds may be refunded after handling costs; spent amounts and partial refunds are not covered.
Bottom line
Use DeepSeek’s $0 chat if you want editable drafts and can check every important answer. Pay for the API only if you already have a technical workflow; skip it for confidential client work, dependable research, or customer-facing automation.
