Run all models with the same API endpoint

You can now use the POST /v1/predictions HTTP API endpoint to run any model on Replicate, whether it’s an official model or a community model. This removes the confusion about which endpoint to use for different types of models.

What changed?

The POST /v1/predictions endpoint now accepts official model identifiers in the owner/name format, in addition to the existing {owner}/{name}:{version_id} and {version_id} formats.

The existing POST /v1/models/{model_owner}/{model_name}/predictions endpoint will still be supported for running official models. If you’re already using that endpoint, you don’t need to change anything.

This change is backward compatible. Existing code will continue to work without any modifications.

Supported version identifiers

When using the POST /v1/predictions endpoint, you can specify models in these formats:

  • {owner}/{name} - For official models (e.g., black-forest-labs/flux-schnell)
  • {owner}/{name}:{version_id} - For community models with full version ID (e.g., replicate/hello-world:9dcd6d78e7c6560c340d916fe32e9f24aabfa331e5cce95fe31f77fb03121426)
  • {version_id} - Just the 64-character version ID (e.g., 9dcd6d78e7c6560c340d916fe32e9f24aabfa331e5cce95fe31f77fb03121426)

Example

Here’s an example of how to run an official model (in this case, black-forest-labs/flux-schnell) using the POST /v1/predictions operation:

curl -X POST https://api.replicate.com/v1/predictions \
  -H "Authorization: Token $REPLICATE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "version": "black-forest-labs/flux-schnell",
    "input": {
      "prompt": "A photo of a cat"
    }
  }'
