Chat Completions API

The chat completions API also support passing multimodal data such as images. This can be either an image URL or a base64 encoded image. You can find examples of both of these below.

Note: Latest guidelines recommend moving towards the Responses API for more advanced features. We currently do not support this, but will support it shortly.

For file uploads, we support a maximum file size of 20 MB.

See the official OpenAI documentation for the most up to date documentation.

Image URL Based

from openai import OpenAI client = OpenAI( base_url="https://api.ncompass.tech/v1", api_key="YOUR_API_KEY", ) response = client.chat.completions.create( model="meta-llama/Llama-4-Maverick-17B-128E-Instruct-FP8", messages=[ { "role": "user", "content": [ { "type": "text", "text": "what is in this image?" }, { "type": "image_url", "image_url": { "url": "https://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Gfp-wisconsin-madison-the-nature-boardwalk.jpg/2560px-Gfp-wisconsin-madison-the-nature-boardwalk.jpg" } } ] } ] ) print(response)

Base64 Encoded

If you’re uploading a file that’s stored locally on your file system.

import base64 from openai import OpenAI client = OpenAI( base_url="https://api.ncompass.tech/v1", api_key="YOUR_API_KEY", ) # Function to encode the image def encode_image(image_path): with open(image_path, "rb") as image_file: return base64.b64encode(image_file.read()).decode("utf-8") response = client.chat.completions.create( model="meta-llama/Llama-4-Maverick-17B-128E-Instruct-FP8", messages=[ { "role": "user", "content": [ { "type": "text", "text": "what is in this image?" }, { "type": "image_url", "image_url": { "url": f"data:image/png;base64, {encode_image('PATH_TO_IMAGE')}", } } ] } ] ) print(response)
