Form Recognizer compose feature limit: documentation says 100 but response error just 5

Question

On Microsoft documentation says (link):

With Model Compose, you can compose up to 100 models to a single model ID. When you call Analyze with this composed model ID, Form Recognizer will first classify the form you submitted, matching it to the best matching model, and then return results for that model. This is useful when incoming forms may belong to one of several templates.

But I'm trying this feature composing 6 models and I'm getting this error from Form Recognizer API

{
    "error": {
        "code": "1001",
        "message": "Parameter 'ModelIds' models count exceed limit for compose: 5."
    }
}

API version: v2.1-preview.1

Answer 1

The Form Recognizer Free resource supports 5 models per model compose. Please upgrade to a paid resource which supports up to 100 models within a model compose to compose more than 5 into a model compose.
