r/n8n on Reddit: How can I benefit from the free API credits from OpenAI?
April 21, 2025 -
Hey guys - I know that there was (sometime ago) the possibility of getting your hands on some free credits for OpenAI api. I want to start working with n8n and I'm quite strapped for cash now.
I haven't seen any kind of new offers on the OpenAI chat and I was wondering if the promos are off the table or are available in some dark corner of the internet?
Thanks!
EDIT: Thank you all for your great inputs!

If you're trying to explore AI + n8n without spending much (or anything), here's what actually works right now: OpenAI still provides free tokens if you enable "share data for training" in your settings. Just make sure your account has a positive balance — even a small one — or the tokens won’t apply. OpenRouter has a bunch of models you can use without an API key. You can send HTTP requests directly from n8n. Models like LLaMA, DeepSeek, MythoMax, and others are available for free. Gemini API from Google gives free access to Gemini Flash (2.5). You can use it with an API key via Google AI Studio — generous daily limits and solid speed. Hugging Face offers some free inference credits if you're on a Pro plan. Not huge, but good enough for testing out flows. With this stack, you can already build working automations and demos without needing any paid API plans.

Rate limit reached means you need to wait for some time before you retry the API request. The response from OpenAi api usually tells you how long you need to wait before retyring.
