Built by a developer, for developers

What We Provide

FreeLLMKeys provides free, OpenAI-compatible API keys that give you access to over 90 AI models — including GPT-4o, Claude Opus 4, Gemini 2.5 Flash, DeepSeek V3, Grok, Mistral, Qwen, and Llama — through a single, unified endpoint. There is no account registration, no credit card, and no rate-limit gating beyond the natural constraints of the keys themselves.

Each key comes with a $20–$100 usage budget and expires within 24–48 hours. Rate limits vary by model tier, typically ranging from 3 to 20 requests per minute. These constraints make the keys ideal for what they are designed for: testing ideas, learning, prototyping, and exploring the capabilities of different AI models side by side.

The API endpoint is fully compatible with the OpenAI SDK, meaning you only need to change the base_url in your existing Python, JavaScript, or any other SDK-based code. No other changes are needed — the same function calls, the same response format, the same streaming patterns.

Who This Is For

We built FreeLLMKeys for a specific set of people who keep running into the same friction point: the paywall.

• Developers prototyping AI apps — you want to test whether GPT-4o or DeepSeek is better for your use case before committing to a paid plan. FreeLLMKeys lets you run that comparison today, for free.
• Students learning prompt engineering — course material often assumes you have a paid API subscription. We remove that assumption so you can follow along and experiment without cost.
• Researchers comparing models — need to benchmark Claude against Gemini on a specific task? Both models, one endpoint, zero spend.
• Indie hackers building MVPs — validate your idea with real AI inference before you scale. The free keys handle the proof-of-concept phase so you can spend your budget on what matters.

Our Commitment

We refresh keys multiple times daily so there is always a working key available when you need one. The page auto-updates every five minutes — you never need to manually reload to get the latest batch.

We do not log your API requests. We do not require a signup, email address, or any personal data to use the keys. We do not sell data. The only third-party data collection on this site is standard web analytics (Google Analytics, which you can opt out of) and advertising (Google AdSense, which follows standard industry opt-out mechanisms).

We also maintain a full Privacy Policy, Terms of Use, and Disclaimer — available in the footer — because transparency matters. We want you to know exactly what you are and are not getting when you use this site.

What FreeLLMKeys Is Not

To be fully transparent: FreeLLMKeys is not a production-grade API service. The keys are shared, have limited budgets, and expire. If another user exhausts a key before you copy it, it will not work. For any application where reliability, SLA guarantees, or data privacy are requirements, you should use the official paid APIs from OpenAI, Anthropic, Google, or the relevant provider.

FreeLLMKeys exists at the intersection of learning and experimentation. Use it for what it is good at, and graduate to paid plans when your project demands it.
