Seed Parameter in DALL·E 3 API

The API documentation does include a seed parameter for image generation endpoints—even for DALL·E 3. This parameter is optional and currently in beta, which means:

• Deterministic Sampling: When you specify a seed along with your other parameters, the system will make a best effort to return the same result on repeated requests with the same seed and parameters.
• Beta Limitations: Because this feature is still in beta, determinism is not fully guaranteed. It’s recommended to check the system_fingerprint in the response to monitor any backend changes that might affect the output.

Here’s an example snippet of how you might include the seed parameter in your API call:

JSONCopied
{
  "prompt": "A beautiful sunset over the ocean",
  "seed": 123456,
  // other relevant parameters...
}

This should allow you to generate images more consistently when reusing the same prompt. However, note that the behavior might evolve as the feature progresses beyond its beta stage.
