AI API limit reached

[raowaqar]

Hi I’m setting up an AI agent to move Circlback notes to Asana and Email.

Sometime, meetings are longer than 2 hrs and sometime we have multiple meetings in a single day.

In this case, I got an error about AI API limit reached.

Please can you povide me a solution to avoid this?

Sure, don’t reach the limit. Easy!

In all seriousness, you didn’t even mention which node fails with error, what is the exact error wording… Give us something to work with

Open AI chatmodel node in first AI agent, fails the error and error is:

{
“errorMessage”: “OpenAI: Rate limit reached”,
“errorDescription”: “Rate limit reached for gpt-4o-mini in organization org-VDEnAyPI7gRtloHECos0S7IM on tokens per min (TPM): Limit 200000, Used 193743, Requested 63058. Please try again in 17.04s. Visit https://platform.openai.com/account/rate-limits to learn more.”,

Ok, so the error basically says:

you have a budget of 200k tokens per minute for gpt-4.1-mini model and your requests exceeded that limit.

How to “fix” it:

• space out requests to the model in time
• go from tier 1 user to tier 2 user (if I remember correctly for that you need to have paid $50 and waited 7+ days since first successful payment
