Why am I receiving a 429 rate limit error when using the DALL‑E 3 API?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I am trying to generate an image using the DALL‑E 3 API but I keep encountering a rate limit error (0/1min limit, current usage 1/1min).

Here is the command I used:

BASH
curl https://api.openai.com/v1/images/generations   -H "Content-Type: application/json"   -H "Authorization: Bearer sk-xxx"   -d '{
    "model": "dall-e-3",
    "prompt": "A cute baby sea otter",
    "n": 1,
    "size": "1024x1024"
  }'
{
  "error": {
    "code": "rate_limit_exceeded",
    "message": "Rate limit exceeded for images per minute in organization org-xxx. Limit: 0/1min. Current: 1/1min. Please visit https://platform.openai.com/docs/guides/rate-limits to learn how to increase your rate limit.",
    "param": null,
    "type": "requests"
  }
}```

I've confirmed that my API key is valid, my credit card is linked, and I have added $10 in credits. I am on the Free tier since I've only spent 6 cents so far. Is this behavior expected on the free tier or could it be a misconfiguration on my end?

Rate Limit Exceeded: What's Happening

The error you're encountering is not a bug with DALL‑E 3 itself but indicates that your organization’s API rate limit for image generations has been exceeded. Specifically, your project appears to allow 0 requests per minute (i.e., it’s already hit the limit when you submit a request), which is enforced on a per-organization basis.

What Could Be the Cause?

Free Tier Limits:
Even though your API key is valid, your credit card is added, and you have credits, free tier projects often come with very strict rate limits. This is why you see a “0/1min” limit message.
Organization-wide Usage:
Rate limits are applied to the entire organization and not per individual API key. Ensure that no background scripts, loops, or other users are unintentionally making image generation requests.

How to Address This

Pace Your Requests:
Avoid making frequent or concurrent calls. Ensure that you have implemented proper retry logic or a backoff mechanism if you’re automating requests.
Review Your Plan:
Check your rate limits guide for details. Upgrading to a higher tier or adjusting your project settings may provide you with increased limits.
Contact Your Organization Owner or Support:
If you believe you haven’t exceeded the allowed usage, or if you need higher limits, you might consider reaching out to your organization’s owner or contacting OpenAI support to discuss increasing your rate limit.

In Summary

This isn’t a known issue with the DALL‑E 3 API; it’s an indication that you’ve hit or been assigned a low rate limit for image generations. Adjusting your usage pattern or plan should help resolve the error.

Feel free to ask if you have any more questions about managing API rate limits!
