How to use DeepSeek API for free?
DeepSeek's own API is paid (though cheap), but you can use DeepSeek models via an API for free three ways: third-party hosts like OpenRouter that offer free DeepSeek endpoints, any trial credit DeepSeek gives new accounts, or by running the open-weight model locally with Ollama, which exposes a free local API on your own machine.
Why — the first-principles explanation
DeepSeek's first-party API charges per token because someone has to pay for the GPUs. So 'free API access' means finding a path where someone else eats that cost, or where you supply the hardware. There are three such paths, and understanding why each is free tells you its limits.
The first is third-party hosts like OpenRouter, which sometimes offer free tiers of DeepSeek's open models. They can do this because the models are open-weight (MIT License), so any provider can serve them; free tiers are loss-leaders to attract users and usually come with rate limits or slower speeds. The second is promotional credit — DeepSeek and cloud marketplaces occasionally hand new accounts a small balance to try the API, which is temporary. The third, and most durable, is self-hosting: run the open model with Ollama or vLLM, and it exposes a local OpenAI-compatible API endpoint that costs nothing per call because your own computer is doing the work.
The honest trade-off: hosted free tiers give you real API URLs but throttle usage and may log your data; self-hosting is unlimited and private but requires capable hardware and technical setup. There's no free lunch — you're choosing who pays, in money, speed, or privacy.
An example that makes it click
Imagine you want unlimited coffee via a drive-through window (an API). The coffee shop charges per cup (DeepSeek's paid API). To get it 'free,' you have three options: find a rival shop giving away sample cups to new customers, but only a few per hour (a third-party free tier); use the coupon the shop mailed you when you signed up (trial credit); or — since the recipe is public — set up your own espresso machine at home and pour as much as you want, paying only for beans and electricity (self-hosting with Ollama).
The home machine is the only truly unlimited one, but you have to buy and run the machine. The sample cups are easy but rationed. Every 'free' path just shifts who's covering the cost of the coffee.
How to do it
- Option A — Third-party free tier: sign up at a host like OpenRouter and use its free DeepSeek endpoint with their base URL and key (expect rate limits).
- Option B — Trial credit: create a DeepSeek account at platform.deepseek.com and use any promotional credit granted to new users.
- Option C — Self-host (best for unlimited/free): install Ollama, run `ollama run deepseek-r1:8b`, and call the local API at http://localhost:11434.
- Point your OpenAI-compatible code at whichever base URL you chose and set the model name accordingly.
- Check each provider's rate limits and data-logging policy before sending sensitive prompts.
- For private, unmetered use, prefer the local Ollama option over hosted free tiers.
Key facts
- DeepSeek's first-party API is paid; there is no permanent official free API tier.
- Third-party hosts (e.g. OpenRouter) sometimes offer free DeepSeek endpoints because the weights are open (MIT License).
- New DeepSeek or cloud-marketplace accounts occasionally receive limited promotional credit.
- Running the open model locally with Ollama or vLLM gives a free, unlimited local API on your own hardware.
- Free hosted tiers typically impose rate limits and may log requests; self-hosting avoids both.

Can you use the DeepSeek API for free? DeepSeek's own API is paid — but it's cheap, and there are three ways to get API access for free. First, third-party hosts like OpenRouter sometimes offer free DeepSeek endpoints, because DeepSeek's models are open source and anyone can serve them; just expect rate limits. Second, new accounts occasionally get a bit of trial credit to test the API. But the best free option is self-hosting: install Ollama, run a command like `ollama run deepseek-r1:8b`, and it gives you a free local API on your own computer — unlimited and private, with no per-call cost. The trade-off is you need decent hardware. So pick your path: rationed free tier, temporary credit, or run it yourself for truly free, unlimited access.
What authoritative sources say
People also ask
Is there an official free DeepSeek API?
No permanent one. The official API is paid, though new accounts sometimes get limited trial credit.
What's the best truly-free option?
Self-hosting with Ollama or vLLM — it gives you an unlimited, private local API for the cost of your own hardware and power.
Are free third-party tiers safe for sensitive data?
Be cautious — they may log requests and impose rate limits; use local self-hosting for private prompts.
Why can third parties offer DeepSeek for free?
Because the models are open-weight under the MIT License, any provider can host them and offer a free tier as a loss-leader.
