r/OpenAI on Reddit: More people need to realize how far $20 of API credit will take you. Also,: What's your favourite web interface to the API?
August 28, 2024 -

Basically the post. I'm surprised at the number of people paying for plus and not using any of the features beyond basic LLM stuff. It's so easy to get an API key and $20 of heavy usage would probably still go far.

That said, I use it from the shell, and was wondering if anyone knows of particularly good web interfaces where you can just plug your API key in. Or alternatively, if there is a local app for Mac or Windows that would be more secure.

How can I set up prepaid billing? | OpenAI Help Center
If your usage exceeds the credits you've purchased, you'll then be billed for the additional amount. Prepaid billing helps developers know what they are committing to upfront which can provide more predictability for budgeting and spend management. Here is how monthly billing or new API users can set up prepaid billing:

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!

Choose how many credits you want to buy and decide if you want to recharge credits automatically, but be careful here as costs can rack up really quickly. Set up your initial credit purchase and auto-recharge · Once you’ve done that, you’ll see your balance and auto-recharge settings. ... If you’re calling OpenAI APIs in frequent automations, you can end up spending a lot of money, really fast, so I recommend setting some limits, which you can do via the Limits option in the left nav directly below billing.

Free OpenAI API Credits: Get & Use Guide
March 24, 2025 - In December 2024, OpenAI introduced an initiative where organizations can receive free API tokens simply by opting to share their prompts (inputs) and completions (outputs) with OpenAI. Initially planned to run until February 28, 2025, the program has now been extended until April 30, 2025 (source). This means businesses and research organizations can access OpenAI's powerful models at a significantly lower cost, provided they opt-in and contribute to model improvements.
