r/OpenAI on Reddit: The best way to use the API key
May 6, 2025 -

Hello guys

Using the OpenAI API key can be cheaper than a GPT plus subscription

But the playground is not build to use in the long term GPT, it is good for small questions but not made like ChatGPT : no memories across the devices, no folder

I would like to use the API in a good environment on my phone, on my PC

So I discovered chatbotui on the website but there was not the news models

I heard about Vercel

I discovered SDK with possibility of integrate OpenAI key

Do you guys have a simple or effective way to made a ChatGPT like with our own API key

Trying to learn how to use OpenAI API for a personal project -- advice appreciated
The cost is negligible. I'm an API customer, developing an app that creates a collection of personality chatbots the user engages, and I'm testing this framework as a single developer dozens of times a day. Granted, I'm one person, running about 10 chat sessions simultaneously ( the same conversation goes through each chatbot, because each chatbot has unique responses within the group conversation ) and my OpenAI bill last month was just over $3.00 (US currency). Plus, they have spending caps you can put in place. More on reddit.com

How does OpenAI API handle API key rotation?
Regular rotation is recommended. Create a new key, update your applications to use it, and then deactivate the old key to minimize service disruption.

r/ChatGPT on Reddit: Using API keys: What you need to know (FAQ for non-devs)
October 10, 2023 -

Do I need to be a developer to use an API key? No

Do I need some special knowledge? No, anyone can use it, either through the OpenAI playground (https://platform.openai.com/playground) or other 3rd party apps that allow you to use your key.

Where can I get my own API key? You need to register and log in here: https://platform.openai.com/account/api-keys you also need to set up your payment details with OpenAI to activate your API key.

What's an API key, and why do I need it? ChatGPT is great, but the app has only a limited set of features. OpenAI provides programmatic access to their models via the APIs so devs can use it to build other apps for any use case. An API key is like a personal password. When you use apps with your key, the usage will be billed to your account. The reason why it's become a popular model nowadays is because you only get to pay for what you use and avoid subscriptions.

How and when can I use it? An example could be getbeam.ai, a native ChatGPT app for Mac. This app provides an alternative ChatGPT UI and lets you use your API key. This means you only pay for what you use instead of paying some subscription or monthly fee.

How much does it cost? Is it expensive to use APIs? GPT-3.5 is very cheap; you can use it all day, every day, and your monthly bill will most likely stay under $5

- GPT-4 is more expensive (input: $0.03 / 1K tokens, output: $0.06 / 1K tokens), but it still depends on your usage.

I mostly use GPT-4 as a Google replacement for programming; my prompts are usually quite short, and I don't need 5000-word essays. So, my monthly bill has constantly stayed around $5. But I know some power users who spend $100+/mo

Is it safe to share my API key with 3rd party apps? Yes and No. If some bad actor gets access to your API key two things can happen: they'll use it, and you'll end up paying the bill. They misuse it, and your account can be banned.

The first can be mitigated by setting the spending limit so it will never exceed $20, for example.

If you're using apps from credible sources and have a spending limit on your account, you should be OK.

Can I have multiple API keys? Yes, you can generate multiple API keys. This can be useful if you want to track usage across different applications.

Can APIs replace ChatGPT? Not entirely. When OpenAI rolls out new features to ChatGPT, they're usually unavailable via the APIs immediately. They're not always in sync.

In summary, if you see 3rd party apps saying "Requires OpenAI API Key," it only takes a few clicks to set up. Be careful with how you manage your key to avoid potential misuse. Never share it with random people. Make sure to set the spending limit and only use apps that you can trust.

r/MLQuestions on Reddit: Trying to learn how to use OpenAI API for a personal project -- advice appreciated
December 14, 2023 -

Hey everyone,

I'm a college student working on a personal project and I think I might be able to use the OpenAI API to help me but I'm not sure if it's the best tool or how to use it properly.

I've written a script that scrapes my college's daily dining website and collects a list of all the dishes being served that day. The idea is that the user could enter some input like "protein, Asian" and the code could find the foods that best match the user's query, in this case, "egg fried rice" and "kung pao chicken." Or "vegetarian, healthy, breakfast" would output "overnight oats with blueberries."

OpenAI's API requires you to pay for it, but I don't really understand the pricing structure. if the cost is negligible then I don't mind paying it.

Any help is appreciated, thanks in advance!
