This source explicitly requests JSON Object mode and Agno attempts local validation against MovieScript.

output_schema describes the expected type. If parsing or validation fails, result.content can remain a string. Before accessing schema fields in a run result, use isinstance(result.content, YourSchema), replacing YourSchema with the class you passed as output_schema.

Run the Example

Set up your virtual environment

uv venv --python 3.12
source .venv/bin/activate

Install dependencies

uv pip install -U agno groq

Export your Groq API key

export GROQ_API_KEY="your_groq_api_key_here"

Run the example

Save the code above as structured_output.py, then run:

python structured_output.py
