DeepSeek’s official web chat and mobile apps are listed as free to access. However, free access does not guarantee unlimited, uninterrupted, or permanent availability. The official API is billed by token usage, while running supported DeepSeek models locally may require paid hardware, cloud servers, storage, electricity, security controls, and technical maintenance.
The simplest way to think about it is this:
DeepSeek’s hosted chat and official mobile apps are currently free to access. The DeepSeek API is billed by token usage. Some DeepSeek model weights are available under permissive licenses, but downloading or self-hosting them does not eliminate infrastructure and operational costs.
DeepSeek’s official homepage advertises “Free access to DeepSeek” for the chat product and separately links to API access for developers. The official Google Play and Apple App Store listings also describe the DeepSeek app as a free official AI assistant.
DeepSeek Free vs Paid: Quick Comparison

| Third-party DeepSeek tools | Depends on provider | Users who want DeepSeek inside another app | Provider pricing, data handling, model version, limits, reliability |
What “Free” Means With DeepSeek
“Is DeepSeek AI free?” sounds like a simple question, but the answer depends on which DeepSeek product you mean.
For a regular user, “free” usually means opening DeepSeek in a browser or mobile app and chatting without paying a subscription. For a developer, “free” may mean API credits, token pricing, or whether a model can be downloaded and self-hosted. For a business, “free” also raises questions about privacy, reliability, commercial terms, and long-term costs.
DeepSeek’s public product pages currently separate the free chat experience from the API platform: the homepage points users to free DeepSeek access while also offering API access for building with DeepSeek models.
Is DeepSeek Chat Free?
Yes. DeepSeek’s official website presents DeepSeek Chat as free access to the model.
That makes the official web chat the easiest option if you want to:
- Ask questions.
- Summarize or rewrite text.
- Get help with coding.
- Draft emails, outlines, or study notes.
- Try DeepSeek before using the API.
- Use AI without setting up a local model.
However, “free” does not mean DeepSeek promises unlimited, uninterrupted, permanent access. DeepSeek’s terms say the service may be added to, upgraded, modified, suspended, or terminated, and they do not guarantee that the service will be uninterrupted, timely, secure, or error-free.
For practical use, treat DeepSeek Chat as a free hosted AI chatbot, not as a guaranteed production system. For software integrations, automations, or customer-facing products, use the API rather than relying on the consumer chat interface. However, API access does not by itself guarantee uptime or a service-level agreement, so production systems should implement retries, monitoring, fallbacks, and error handling.
Is the DeepSeek App Free?
Yes. The official DeepSeek mobile app is listed as free on both Google Play and Apple’s App Store. The Google Play listing says users can interact with DeepSeek’s official AI assistant for free, and the Apple App Store listing also labels the app as “Free.”
The app is suitable for quick everyday use on a phone or tablet. It may not be appropriate for workflows that require organization-managed access controls, audit logs, private deployment, contractual uptime commitments, or programmatic integration.
Before using the mobile app with sensitive information, check the app’s current privacy disclosures. Google Play’s data safety section says the app may share device or other IDs with third parties and may collect data types including location and personal information. DeepSeek’s own privacy policy also says it may collect account data, user inputs, uploaded files, photos, chat history, device/network data, logs, approximate location based on IP address, and payment data for paid open-platform services.
Is DeepSeek API Free?
No, not as a general rule. DeepSeek API usage is priced by tokens.
DeepSeek’s API pricing page says prices are listed per 1 million tokens, and billing is based on the total number of input and output tokens processed by the model. A token is a small unit of text used by the model for processing and billing; DeepSeek’s token documentation explains that a token can roughly correspond to a word, character, number, or symbol, depending on language and tokenization.
Current DeepSeek API Pricing
As verified on July 29, 2026, DeepSeek’s official API pricing page lists usage-based prices for its available API models. The summary below is included only to explain why the API is not free. For detailed calculations, cached-input pricing, cost examples, and future updates, see our current DeepSeek API pricing guide.
See the complete DeepSeek API pricing and cost guide for detailed rates, calculations, and budgeting examples.
| API model | Context length | Max output | Input price, cache hit | Input price, cache miss | Output price |
|---|---|---|---|---|---|
deepseek-v4-flash | 1M tokens | 384K tokens | $0.0028 / 1M tokens | $0.14 / 1M tokens | $0.28 / 1M tokens |
deepseek-v4-pro | 1M tokens | 384K tokens | $0.003625 / 1M tokens | $0.435 / 1M tokens | $0.87 / 1M tokens |
Current DeepSeek API pricing (verified August 16, 2026): DeepSeek uses peak rates during 01:00–04:00 and 06:00–10:00 UTC and off-peak rates at all other times. Flash off-peak / peak rates are $0.007 / $0.22 / $0.66 and $0.014 / $0.44 / $1.32; Pro off-peak / peak rates are $0.022 / $0.66 / $1.98 and $0.044 / $1.32 / $3.96, in cache-hit input / cache-miss input / output order. Use the current pricing page and time-aware cost calculator for new budgets. Any dated prices, test costs, or arithmetic elsewhere on this page remain historical and have not been recomputed.
Legacy API status (verified July 29, 2026): DeepSeek’s April 24 V4 notice set July 24, 2026 at 15:59 UTC as the cutoff for deepseek-chat and deepseek-reasoner. That deadline has passed. The current official model list shows only deepseek-v4-flash and deepseek-v4-pro. A bounded Chat-Deep.ai test on July 28 observed both aliases still returning Flash, but that is undocumented compatibility behavior—not an official support guarantee. New integrations should use a listed V4 ID and set thinking mode explicitly.
Prices can change. DeepSeek’s pricing page says product prices may vary, that DeepSeek reserves the right to adjust them, and that users should regularly check the pricing page for the latest information.
How DeepSeek API Token Pricing Works
DeepSeek API costs are calculated from:
- Input tokens — the text you send to the model.
- Output tokens — the text the model generates.
- The selected model — for example, V4 Flash or V4 Pro.
- Cache status — cached input can be cheaper than uncached input.
- Usage volume — more requests and longer outputs cost more.
DeepSeek’s pricing page states the deduction rule simply: expense equals number of tokens multiplied by price, and fees are deducted from topped-up balance or granted balance if available.
Example API Cost Calculation
Suppose you use deepseek-v4-flash and send a request with:
- 10,000 uncached input tokens.
- 5,000 output tokens.
Using the checked prices:
- Input cost: 10,000 / 1,000,000 × $0.14 = $0.0014
- Output cost: 5,000 / 1,000,000 × $0.28 = $0.0014
- Estimated total: $0.0028
This example is only for explaining the formula. Real costs depend on your exact token usage, cache behavior, model, and the current official pricing at the time you call the API.
Does DeepSeek API Have a Free Tier?
DeepSeek’s public API documentation distinguishes between granted balance and topped-up balance. However, the presence of granted balance for an account does not constitute a permanent or universally available free API tier. Any promotional or granted credit may be account-specific and may have an expiration date shown on the DeepSeek Platform billing page.
In practice, this means you should not build a product assuming DeepSeek API will be free. Check your own DeepSeek Platform billing page for any granted balance, expiration date, and available credits.
DeepSeek’s FAQ says topped-up balance does not expire, while granted balance may have an expiration date visible on the Billing page. It also says users can top up online through PayPal, bank card, Alipay, or WeChat Pay.
Does DeepSeek Require a Credit Card?
Not necessarily. DeepSeek’s hosted web chat and official mobile apps are currently listed as free to access and generally do not require users to purchase an API balance.
For API usage, you need an API key and sufficient available balance. DeepSeek’s documentation states that a 402 Insufficient Balance error means the account does not have enough balance to complete the request.
A bank card is not the only payment method listed in DeepSeek’s FAQ. Depending on availability and account region, the documented top-up methods include PayPal, bank card, Alipay, and WeChat Pay.
Are There Usage Limits?
There are clear limits for the API, but they are not the same as a daily message cap for the free chat product.
For the API, DeepSeek documents concurrency limits of 2,500 for deepseek-v4-flash and 500 for deepseek-v4-pro. A request counts as one concurrent connection from when it is sent until the model response is complete, and requests over the concurrency limit may receive an HTTP 429 error.
DeepSeek’s error-code documentation also lists 429 Rate Limit Reached, 500 Server Error, and 503 Server Overloaded, which matters if you are building production software on top of the API.
For the hosted web chat, DeepSeek’s terms do not promise uninterrupted service, and service availability can change. If your workflow cannot tolerate outages, queue delays, or temporary restrictions, do not rely only on the free chat interface.
Which DeepSeek Models Have Open Weights?
Some specific DeepSeek model releases are available with downloadable weights and permissive licenses. This does not mean that every DeepSeek model, hosted service, application, API component, or associated technology is open source. Always review the repository and license for the exact model version you intend to download, modify, distribute, or use commercially.
DeepSeek announced DeepSeek V4 Preview as “officially live & open-sourced” and said it is available on web, app, and API. The Hugging Face page for DeepSeek-V4-Flash says the repository and model weights are licensed under the MIT License.
DeepSeek-R1-0528’s Hugging Face page says the code repository and model use are subject to the MIT License and that the R1 series supports commercial use and distillation. DeepSeek-V3’s GitHub repository says the code is MIT-licensed, while the V3 Base/Chat models are subject to the Model License and support commercial use.
The important distinction is this:
Open weights or an MIT license may reduce licensing cost, but they do not eliminate infrastructure cost.
If you run DeepSeek locally or self-host it in the cloud, you are responsible for the hardware, GPU memory, inference framework, storage, deployment, monitoring, scaling, and security.
Is Running DeepSeek Locally Free?
Not really. You may be able to access some model weights without paying a license fee, but running a large AI model has real costs.
Local deployment can require:
- A capable GPU or multiple GPUs.
- Enough VRAM for the model or quantized version.
- Storage for model weights.
- Inference software such as vLLM, SGLang, or other supported frameworks.
- Electricity or cloud compute.
- Setup, monitoring, and maintenance time.
- Security controls if users or business data are involved.
DeepSeek’s V4 model page includes local deployment instructions and recommends specific deployment settings for reasoning mode. The V3 repository also references inference support through frameworks such as vLLM, LightLLM, and hardware-specific deployments.
For most non-technical users, the hosted chat is easier than running a model locally. For developers, the paid API may also be simpler than managing self-hosted inference. Local deployment can provide greater infrastructure control, but it is not automatically private, compliant, or secure. Teams must still configure access controls, encryption, network security, software updates, monitoring, retention policies, and incident-response procedures.
Hidden Costs to Consider
Even if DeepSeek feels free at first, the real cost depends on how you use it.
1. API Usage Can Grow Quickly
Short prompts cost very little, but long documents, repeated calls, tool use, agent workflows, and long outputs can increase token usage. Developers should log token usage and set internal budgets before using the API in production.
2. Free Chat Is Not a Service-Level Agreement
The free chat product may be useful for everyday work, but it is not the same as a contracted enterprise service. DeepSeek’s terms do not guarantee uninterrupted or error-free access.
3. Local Models Shift the Cost to You
Self-hosting can reduce API dependency, but it introduces hardware, deployment, DevOps, and security costs. “Free model weights” should not be confused with “free inference.”
4. Privacy and Compliance May Matter More Than Price
The DeepSeek Privacy Policy applies to official services that link to or reference it. For those covered services, it describes collection of prompts, uploaded files, chat history, device information, logs, approximate location, and other specified data. It also states that collected personal data is directly processed and stored in the People’s Republic of China.
The policy expressly excludes processing rules for personal data collected from end users inside downstream applications built through the Open Platform. Therefore, the official-service data-residency statement should not be presented as a universal API rule. Identify whether you are using official chat or app access, the Open Platform, a third-party provider, or a self-hosted model before assessing privacy and compliance.
Is DeepSeek Safe to Use With Private or Business Data?
DeepSeek can support business workflows, but safety and privacy depend on the exact access route. A paid API request is not automatically private, compliant, zero-retention, or covered by enterprise contractual protections.
For official DeepSeek Chat and mobile-app use, the official Privacy Policy describes collection and improvement uses, PRC processing and storage, an opt-out right for model training or technology optimization, and categories of sensitive personal data the services are not designed to process.
For a downstream API application, the official-service policy expressly excludes the application operator’s processing of its end users. The DeepSeek Open Platform Terms make the application operator responsible for disclosing its processing rules, establishing a legal basis, responding to applicable rights requests, and implementing technical and organizational safeguards.
The operator must still assess DeepSeek-side processing under the platform terms, account settings, caching, logs, retention, architecture, subprocessors, support access, and any written contract. Paying by token or connecting the API to the operator’s own access-control system does not determine what occurs on the provider side.
Third-party tools have another data path governed partly by that provider’s terms and infrastructure. Self-hosting can provide greater infrastructure control, but the operator assumes responsibility for access, encryption, network security, logs, retention, monitoring, updates, model security, and incident response.
- Use official free chat or app access for general, non-sensitive tasks unless your organization explicitly approves more.
- Use the API when programmatic integration is required, but approve both operator and provider-side data flows first.
- Review third-party DeepSeek services under the provider’s own privacy, security, and contractual terms.
- Consider secured self-hosting only when the organization can operate it responsibly.
- Obtain legal, security, privacy, and compliance approval for confidential or regulated workloads.

Is DeepSeek API free?
No, not generally. DeepSeek API pricing is based on input and output tokens, with prices listed per 1 million tokens. Your account may have granted balance, but you should verify that inside the DeepSeek Platform billing page.
Is the paid DeepSeek API more private than free DeepSeek Chat?
Not automatically. Official chat and app use is governed by DeepSeek’s official-service Privacy Policy. A downstream API application has separate operator responsibilities under the Open Platform Terms, while DeepSeek-side processing must be assessed through the applicable terms, settings, caching, logs, retention, architecture, and contract. Paying by token does not itself guarantee zero retention, a particular processing region, or enterprise-grade privacy controls.
How much does DeepSeek API cost?
As verified on July 29, 2026, DeepSeek’s official pricing page lists usage-based prices that vary by model, input cache status, and output volume. Because prices and available model names can change, review the official pricing page or our dedicated DeepSeek API pricing guide before estimating production costs.
Does DeepSeek have a subscription plan?
DeepSeek’s public official pages checked for this article present the chat/app experience as free and the API as token-billed. They do not show a ChatGPT Plus-style consumer subscription plan in the checked official sources. Always verify the current DeepSeek website and app store listings because product plans can change.
What are DeepSeek API tokens?
Tokens are the units DeepSeek models use to process text and calculate API billing. DeepSeek explains that tokens can be understood roughly as characters or words, although the exact count depends on the model’s tokenizer.
Is DeepSeek open source?
Some DeepSeek models are available with open weights and permissive licenses. For example, DeepSeek-V4-Flash is listed on Hugging Face with model weights under the MIT License, and DeepSeek-R1-0528 is also described as MIT-licensed with commercial use and distillation support. Always check the exact license for the specific model version you plan to use.
Is running DeepSeek locally free?
No, not in practical terms. Even if the model license allows free access to weights, you still need hardware or cloud compute, storage, inference software, monitoring, and maintenance.
Can I use DeepSeek for commercial work?
Commercial use depends on the DeepSeek product, service, and exact model version involved. DeepSeek’s Terms of Use describe rights in generated outputs subject to applicable law and the terms, but users remain responsible for verifying output accuracy, complying with applicable rules, and following any disclosure or attribution requirements that apply when publishing or distributing AI-generated material. For downloadable model weights, review the specific repository and model license because commercial-use, redistribution, modification, and derivative-work conditions may vary by release.
Should I use DeepSeek instead of ChatGPT, Claude, or Gemini?
Consider DeepSeek if you want a currently free hosted chat option, published usage-based API pricing, or access to supported open-weight model releases. Compare it with ChatGPT, Claude, Gemini, and other providers based on model capabilities, availability, integrations, privacy terms, enterprise controls, support, data residency, and your organization’s compliance requirements.
Conclusion: Is DeepSeek AI Free?
As verified on July 29, 2026, DeepSeek’s official web chat and mobile apps are free to access, while API usage is token-billed and local deployment creates infrastructure and operational costs.
Use the free chat or app if you want a no-cost AI assistant for general tasks. Use the API if you are building software and can manage token-based costs. Consider local deployment only if you have the technical resources and a clear reason to control your own infrastructure.
The best answer is:
