DALL-E Not Working

DALL-E 3 not generating images in ChatGPT or returning API errors? Here’s how to check if OpenAI’s image service is down and how to fix the most common DALL-E issues.

Check live OpenAI status

Prismix monitors OpenAI every 5 minutes — faster than the official status page.

What’s not working?

DALL-E not generating images in ChatGPT

Check if you’re on ChatGPT Plus or Team — DALL-E 3 is not available on the free plan. If you have Plus, the image generation service may be degraded; check live status above. Plus users also have a daily image limit that resets each day.

Content policy violation error

OpenAI’s safety system rejected your prompt. Try a more abstract description: replace real people’s names with descriptive phrases (“a young woman with curly hair”), avoid violence or sensitive themes, and describe artistic styles rather than specific copyrighted artworks.

DALL-E API error 429 (rate limit)

Image generation has strict rate limits — much lower than text. Add retry logic with exponential backoff, reduce concurrent requests, and cache results to avoid regenerating the same images. Upgrading your API tier at platform.openai.com gives higher limits.

DALL-E API error 400 or 500

Error 400 usually means an invalid parameter — check that your size (e.g., 1024x1024) and quality (standard or hd) values are valid for your model version. Error 500 is a server-side issue — wait and retry.

5 fixes to try in order

1

Check if OpenAI image generation is down

Visit prismix.dev/service/openai. Image generation goes down independently of text — an OpenAI incident affecting DALL-E may show no issues for ChatGPT text. Also check status.openai.com for any active incidents.

2

Verify your plan and usage

In ChatGPT: confirm you’re on Plus or Team — DALL-E 3 is not available on free. Via API: go to platform.openai.com/usage to see remaining image generation quota. Daily limits reset at midnight Pacific time.

3

Rephrase your prompt

For content policy blocks: describe people abstractly (“a middle-aged man in a business suit” vs. a celebrity name), use genre terms for art styles (“oil painting style”, “watercolor illustration”), and avoid mentioning violence, weapons, or sensitive scenarios even if the intent is artistic.

4

Check your API key

Verify your API key is active at platform.openai.com/api-keys. Ensure the key has access to the dall-e-3 model. Check your billing settings — image generation is billed per image and requires an active payment method with available credits.

5

Use standard parameters

If getting API errors, try the minimum working config: model: "dall-e-3", size: "1024x1024", quality: "standard", n: 1. Some size/quality combinations aren’t supported by all model versions. DALL-E 2 does not support HD quality — that’s DALL-E 3 only.

n 1 (DALL-E 3) or 1-10 (DALL-E 2) DALL-E 3 only allows n=1

FAQ

Is DALL-E 3 available on the free ChatGPT plan?

No. DALL-E 3 image generation in ChatGPT requires a Plus ($20/month) or Team subscription. Free users can access some image generation through Microsoft Copilot (which also uses DALL-E 3) as an alternative.

What is the DALL-E 3 API pricing?

DALL-E 3 via API costs per image: $0.04 for standard quality 1024x1024, $0.08 for HD quality 1024x1024, and higher for landscape/portrait sizes. Check openai.com/pricing for current rates as they change periodically.

Does DALL-E support image editing or variations?

DALL-E 2 supports image editing (inpainting) and variations. DALL-E 3 does not — it only generates new images from text prompts. For editing, you must use the DALL-E 2 API endpoints, not DALL-E 3.
