Llama OpenAI Image Input File

Attach a local image file to Llama 4 Maverick via the OpenAI-compatible client and stream a description.

At the linked source revision, LlamaOpenAI has a message-formatter signature mismatch and fails before sending a request. Apply the compatible adapter instructions below before running this example.

Run the Example

Set up your virtual environment

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

Install dependencies

uv pip install -U agno llama-api-client openai

Export your Meta Llama API key

export LLAMA_API_KEY="your_llama_api_key_here"

Use the compatible API adapter

Replace the LlamaOpenAI import (or Llama in the byte-image source) with this helper. Then replace every LlamaOpenAI(...) or Llama(...) construction in the saved file with llama_model(...). Keep the existing id, temperature, and any retry options inside those calls.

Compatible model helper
from os import getenv

from agno.models.openai.like import OpenAILike


def llama_model(**kwargs):
    return OpenAILike(
        api_key=getenv("LLAMA_API_KEY"),
        base_url="https://api.llama.com/compat/v1/",
        supports_native_structured_outputs=False,
        supports_json_schema_outputs=True,
        **kwargs,
    )

This uses Meta's OpenAI-compatible endpoint. You need a Meta API account with access to the selected model; check your account's current model catalog before running.

Run the example

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

python image_input_file.py
