If I give Cursor my ChatGPT Pro API key, does it draw on the OpenAI account instead of racking up Cursor usage-based fees?
Which is cheaper/better?
The API and Pro/Plus accounts from Openai are not interchangeable. You would have to purchase credits to use the API.
Thank you.
Would the latest o3 model be less expensive through a ChatGPT Pro plan + API fees or a Cursor Pro plan + model-based usage fees plan?
Hey, it all depends on how you use it. In Cursor, each request to the o3 model costs 30 cents, regardless of the number of tokens. Each of your requests can have between 1,000 and 50,000 tokens, both for input and output. If you use your API key, costs are calculated based on tokens, with charges per token. Keep in mind that the API pricing for this model is $10 for input and $40 for output per 1 million tokens.
That is very helpful. Thank you.
Do I lose any functionality working straight off the API key? There are some warnings associated with entering an OpenAI key in the preferences screen, but I didn’t know how seriously to take them.
If you have a Pro subscription, you hardly lose anything, all features should work with your API key. However, if you are on the free plan, only the chat will be available to you with the API.
