Quick answer: Yes, DeepSeek AI is free for normal chat use through the official web chat and mobile app. However, DeepSeek API usage is paid and billed by tokens. Open-source DeepSeek models may be free to download or use under their licenses, but running them locally is not cost-free because you may need GPUs, cloud hosting, storage and technical maintenance. DeepSeek’s homepage says users can “Start Now” with free access, while its official pricing page lists token-based API fees.
Is DeepSeek AI free?
Is DeepSeek AI Free? Yes, for most casual users, DeepSeek is free through the official web chat and mobile app. You can use it for tasks such as writing, coding help, file reading, brainstorming and general AI chat without paying for the API.
The important distinction is how you use DeepSeek. The official chat product and app are presented as free user-facing tools, while the developer API is a metered service. DeepSeek’s official API pricing page states that expenses are calculated as the number of tokens multiplied by the relevant price, then deducted from a topped-up or granted balance.
Quick verdict
- Free for casual chat: Yes, via the official web chat and app.
- Free mobile app: Yes, the official app store listings describe the assistant as free.
- Free API: No, API usage is token-based and paid after any granted balance.
- Free local models: Model access may be free under the license, but hardware and hosting are not free.
- Free forever: Not guaranteed; pricing, access and limits can change.
What is free with DeepSeek?
DeepSeek’s official homepage links to DeepSeek Chat with the wording “Free access to DeepSeek,” and the official app download page points users toward mobile app options.
The official Google Play listing says users can interact with DeepSeek’s official AI assistant for free, and the Apple App Store listing uses similar wording.
In practice, the free side of DeepSeek usually includes:
| DeepSeek access method | Is it free? | Best for | Notes |
|---|---|---|---|
| Official web chat | Yes | Everyday AI chat, writing, coding help, study, brainstorming | Free access does not mean guaranteed unlimited access. |
| Official mobile app | Yes | Mobile chat, productivity, quick answers | Use the official app store listing, not clone apps. |
| Supported chat models in the interface | Usually yes for normal users | Reasoning, coding, content and file-related tasks | Available models and modes can change. |
| Open-source model repositories | Often yes under stated licenses | Developers, researchers, local deployment | Running the model still has infrastructure costs. |
Free access also does not mean there are no tradeoffs. A free AI tool can still have usage limits, temporary slowdowns, privacy considerations, regional availability issues or model changes.
What is not free?
The main paid part of DeepSeek is the DeepSeek API. Developers who want to integrate DeepSeek into an app, website, automation workflow or internal business tool should treat API usage as a paid, metered service.
DeepSeek’s API documentation explains that token usage is used for billing, and that tokens are the basic units models use to represent text.
Costs may apply to:
- API input tokens
- API output tokens
- Cache-hit and cache-miss input tokens
- Production app usage
- Cloud servers or GPU instances
- Local model hosting
- Storage and monitoring
- Developer time
- Maintenance, security and scaling
DeepSeek’s billing FAQ says users can top up through PayPal, bank card, Alipay or WeChat Pay, and that topped-up balances do not expire, while granted balance expiration can be checked in the billing page.
DeepSeek API pricing explained
This section is a short pricing summary to explain why the DeepSeek API is not fully free. For the full token pricing table, discounts, examples, and cost calculator, read our DeepSeek API pricing guide.
DeepSeek API pricing is based on tokens. In simple terms, a token is a small unit of text. DeepSeek’s documentation says tokens are used for billing and can roughly correspond to words, characters, numbers or symbols, although the actual count depends on the model’s tokenizer.
DeepSeek’s current API pricing page lists DeepSeek-V4-Flash and DeepSeek-V4-Pro with a 1M context length and up to 384K maximum output. It also notes that the old deepseek-chat and deepseek-reasoner names are planned for deprecation in the future and currently map to modes of deepseek-v4-flash.
Current DeepSeek API pricing table
| Model | 1M input tokens, cache hit | 1M input tokens, cache miss | 1M output tokens | Context length |
|---|---|---|---|---|
| DeepSeek-V4-Flash | $0.0028 | $0.14 | $0.28 | 1M |
| DeepSeek-V4-Pro | $0.003625 | $0.435 | $0.87 | 1M |
For a deeper breakdown, see our dedicated DeepSeek pricing guide. This page focuses on whether DeepSeek is free, while the pricing guide focuses on detailed API costs.
The DeepSeek-V4-Pro prices above were shown as a 75% discounted rate on DeepSeek’s official pricing page, extended until May 31, 2026 at 15:59 UTC. The same page says prices may vary and recommends checking the pricing page regularly before topping up.
Cache hit vs cache miss
A cache hit means part of your input can be reused from DeepSeek’s context cache, making it cheaper. A cache miss means the input was not reused from cache and is charged at the normal cache-miss input price.
DeepSeek’s context caching documentation says the API response includes prompt_cache_hit_tokens and prompt_cache_miss_tokens so developers can see how much of the prompt hit or missed the cache. It also says caching works on a best-effort basis and does not guarantee a 100% cache hit rate.
Example API cost calculation
Suppose your app sends 1 million cache-miss input tokens and receives 500,000 output tokens.
For DeepSeek-V4-Flash:
- Input: 1 × $0.14 = $0.14
- Output: 0.5 × $0.28 = $0.14
- Estimated total: $0.28
For DeepSeek-V4-Pro at the discounted price shown on May 12, 2026:
- Input: 1 × $0.435 = $0.435
- Output: 0.5 × $0.87 = $0.435
- Estimated total: $0.87
This is only a simplified example. Real costs depend on model choice, input size, output length, cache performance, retries and application traffic.
Does DeepSeek have limits?
Yes, but not all limits are published as a fixed number.
For the API, DeepSeek says it dynamically limits user concurrency based on server load. If a user reaches the concurrency limit, the API immediately returns an HTTP 429 response. The documentation also says that if a request has not started inference after 10 minutes, the server closes the connection.
DeepSeek’s FAQ adds that account rate limits are adjusted dynamically based on real-time traffic pressure and short-term historical usage, and that it temporarily does not support increasing dynamic rate limits for individual accounts.
For free web or app use, users should not assume unlimited, guaranteed or always-fast access. Like other AI services, free access can be affected by demand, server load, feature availability, abuse prevention and product changes.
Is DeepSeek open source and free to run locally?
DeepSeek has released several model repositories and open-weight models, but “open” does not always mean “free to operate.”
DeepSeek-R1’s official GitHub repository says the code repository and model weights are licensed under the MIT License, support commercial use and allow modifications and derivative works, while noting that some distilled models are derived from Qwen or Llama models with their own upstream licenses.
DeepSeek-V3’s official GitHub repository says the code is MIT licensed, while DeepSeek-V3 Base/Chat model use is subject to the model license, and the V3 series supports commercial use.
DeepSeek-V4-Pro’s Hugging Face model card says the repository and model weights are licensed under the MIT License and provides local running instructions through tools such as Transformers, vLLM and SGLang.
That means local deployment may be attractive for developers who want more control, but it is not “free” in the practical sense. You may need:
- Suitable GPUs or cloud GPU instances
- Enough VRAM, storage and bandwidth
- Inference software such as vLLM or SGLang
- Engineering time for setup and optimization
- Security, logging and monitoring
- License review for commercial or redistributed use
Free vs paid DeepSeek: which should you use?
| User type | Is free DeepSeek enough? | When payment may be needed |
|---|---|---|
| Casual user | Usually yes | Rarely, unless DeepSeek introduces paid consumer features. |
| Student | Usually yes | If building apps, automations or high-volume projects using the API. |
| Developer testing an app | Sometimes | When using API calls beyond any granted balance. |
| Startup prototype | Maybe | If the product has real users, recurring API traffic or uptime needs. |
| Production app | No | Production usage should be budgeted as a paid API or hosting cost. |
| Enterprise/private deployment | No | Private deployment requires infrastructure, security review and technical support. |
The simplest rule is this: use free DeepSeek Chat or the app for personal use; use the paid API for software integration; use local deployment only if you can manage infrastructure and licensing.
DeepSeek vs ChatGPT pricing: quick comparison
DeepSeek and ChatGPT have different product and pricing structures.
OpenAI’s ChatGPT pricing page lists a Free plan with limited access, messages, uploads and other features, plus paid plans such as Go, Plus, Pro, Business and Enterprise.
OpenAI’s API pricing is separate from ChatGPT subscriptions and is billed by model and token usage. For example, OpenAI’s API pricing page lists per-token pricing for models such as GPT-5.5, GPT-5.4 and GPT-5.4 mini.
| Comparison point | DeepSeek | ChatGPT / OpenAI |
|---|---|---|
| Free consumer chat | Official web/app access is presented as free | ChatGPT has a Free plan with limited access |
| Paid consumer subscription | No separate consumer subscription was listed on the official DeepSeek pages checked | Multiple paid ChatGPT plans are listed |
| Developer API | Token-based DeepSeek API pricing | Token-based OpenAI API pricing |
| Local/open models | Several DeepSeek model weights are available under stated licenses | OpenAI’s flagship models are generally accessed through hosted products/APIs |
| Best fit | Users wanting free chat or developers seeking DeepSeek API/local deployment | Users wanting ChatGPT subscriptions, OpenAI API or broader OpenAI platform features |
Avoid simple claims like “DeepSeek is always cheaper than ChatGPT.” API costs depend on model, output length, caching, latency needs, reliability needs and workload design.
Privacy and safety considerations
Free AI tools still involve data tradeoffs.
DeepSeek’s privacy policy says it may collect account data, user inputs, voice inputs, prompts, uploaded files, photos, feedback, chat history and other content users provide to the model and services. It also says it automatically collects certain device and network data, such as IP address, device identifiers, cookies, logs and approximate location based on IP address.
The same policy says personal data may be stored on servers outside the user’s country and that DeepSeek directly collects, processes and stores personal data in the People’s Republic of China. It also says users should take special care in deciding what personal data they send through the services or email.
For that reason, do not paste sensitive personal, business, legal, medical, financial or confidential information into DeepSeek or any other AI chatbot unless you understand the relevant privacy policy, data handling practices and your organization’s rules.
For higher privacy control, local deployment may reduce reliance on a hosted chatbot, but it does not automatically solve every safety issue. You still need secure infrastructure, access controls, logging policies and license compliance.
How to use DeepSeek for free
- Go to the official DeepSeek website or the official app listing.
- Choose the web chat or download the official mobile app.
- Sign in if required.
- Start a chat and ask your question.
- Use reasoning or expert modes if they are available in the interface.
- Developers should create an API key only if they intend to use the paid API or any available granted balance.
DeepSeek’s Terms of Use define its services broadly to include websites, applications, SDKs, APIs and other generative AI service formats, so users should distinguish between the free chat/app experience and developer platform usage.
Common misconceptions
“DeepSeek API is completely free”
No. DeepSeek API usage is token-based. The cost is calculated from token count and price, then deducted from topped-up or granted balance.
“Open-source means free to run”
Not necessarily. A model license may allow free access or commercial use, but inference still requires hardware, hosting and engineering work.
“Free means unlimited”
No. Free access can still be limited by traffic, product policy, server capacity, abuse controls or regional availability.
“Free means private”
No. DeepSeek’s privacy policy describes the types of data it may collect, including prompts, uploaded files and chat history.
“All DeepSeek websites are official”
No. DeepSeek’s V4 announcement specifically reminds users to rely only on official accounts for DeepSeek news.
“The API and the chat app are the same product”
No. The chat app is a user-facing assistant. The API is a developer service for integrating DeepSeek models into software.
