Is DeepSeek Free? Chat, API and Local Costs Explained

DeepSeek can be free to use, but only in specific senses. The official hosted chat is described as free. The first-party API is metered and paid. Downloading open model weights can avoid provider token charges, yet local hardware and electricity still cost money. Third-party services set their own prices.

Free and paid at a glance

This table was verified on 2026-07-30. Product terms can change, so use the current pricing guide immediately before making a budget decision.

Free hosted chat

DeepSeek’s company site links to “Free access to DeepSeek,” and its app announcement described the first-party mobile app as free. Hosted chat gives users a ready-made interface without creating an API billing account.

Free does not mean unlimited, guaranteed or suitable for every data type. Capacity controls, feature availability and regional access can change. The service also operates under DeepSeek’s terms and privacy policy. Do not treat the lack of a cash price as a reason to submit sensitive information.

Paid API usage

The official API pricing page lists separate rates for cached input, uncached input and output tokens for deepseek-v4-flash and deepseek-v4-pro. Charges are deducted from granted or topped-up balance. The service can return a 402 error when balance is insufficient.

The current exact rates are stored centrally in this pack and explained in DeepSeek API pricing per million tokens. An API key is not included simply because someone can use the chat for free. Do not put a paid key into a public browser app.

What “granted balance” means

DeepSeek’s balance API includes a granted_balance field, which shows unexpired granted funds when an account has them. That technical capability is not proof that every new user receives a free credit amount. No universal free API entitlement was documented on the official pricing and balance pages when checked.

If your account dashboard shows promotional balance, rely on the displayed amount, currency and expiry. Do not extrapolate from an old screenshot or affiliate page. The free API guide explains legitimate alternatives when no credit is available.

Local models are not costless

DeepSeek has released open weights, including R1 and smaller distilled models. Downloading them can eliminate a first-party per-token bill, and local inference can be useful for offline or controlled-data workflows.

Your computer still performs the work. Storage can range from a few gigabytes for a small quantised checkpoint to far more for larger models. More RAM or VRAM can improve what fits and how it runs, but this guide does not promise a speed for a particular device. Electricity, backups, security patching and administrator time are real costs.

Third-party hosting and apps

Cloud marketplaces, AI aggregators and desktop clients can offer DeepSeek-family models under their own billing. A service may provide a temporary free tier, subscription or promotional quota. Those offers belong to that provider and may use a different checkpoint or modified system.

Check the exact model, provider, data policy, context limit and deletion controls. A third-party “unlimited DeepSeek” subscription is not evidence of an official DeepSeek Pro plan. See the Pro plan clarification.

How to choose the least expensive route

For occasional personal questions, start with official chat. For an application, estimate uncached input, expected cache hits and output before topping up. Flash is priced below Pro in the current first-party table, but model choice should also consider task quality and retry rates. A cheap unsuccessful call can cost more after repeated attempts.

For steady local workloads, compare the total cost of hardware and maintenance with hosted usage. Existing capable hardware changes the equation; buying a workstation for light use may not. Pilot with a small model and representative tasks before spending.

Cost mistakes to avoid

Do not confuse the hosted chat with the API. Do not assume every token is billed at the cache-hit price. Do not omit reasoning or tool-call output from estimates. Do not expose keys to users who can generate unlimited charges. Set balance alerts and application-level limits where available.

Coupons and deals also require evidence. This pack found no current official coupon code or general discount on the verification date. The coupon status page and deals guide record that result without inventing an offer.

Conclusion

DeepSeek is free for official hosted chat and can be downloaded in open-weight forms, but the developer API and the computing behind local inference are not free. Identify the route first, then compare its actual bill, data handling and operational work.
