Visual Question Answering (VQA) is transforming how machines understand and interact with visual data. At the intersection of computer vision and natural language processing, VQA systems like the Llava Model provide answers to queries about visual content, combining image recognition with contextual understanding. This blog explores the cutting-edge Llava Model and its integration with ezML, offering a comprehensive guide to implementing a VQA API in various applications.

Understanding the Llava Model in VQA

At the cutting edge of Visual Question Answering (VQA) technology lies the Llava Model, a remarkable embodiment of the latest advancements in AI. This model isn't just about recognizing images; it's about understanding them in context and responding to queries about them with nuanced accuracy.

Core Strengths of the Llava Model:

  • Complex Scene Interpretation: Unlike traditional image recognition models, the Llava Model is adept at dissecting complex visual scenes. It doesn’t just see an image; it analyses the intricate details, identifying and understanding the relationships and interactions within it.

  • Precision in Answering Queries: The Llava Model is engineered to handle a diverse range of queries with precision.

  • Advanced Integration of Vision and Language: At the heart of the Llava Model's effectiveness is its seamless integration of computer vision and natural language processing technologies.

Implementing Llava as a VQA API on ezML

ezML simplifies integrating the Llava Model into your systems, making it accessible even to those with limited technical expertise. Here's how to get started:

Integrating Llava with ezML:

  • Account Setup: Create an account on ezML to get 2500 free deployment credits: ezML Account Setup

  • Authorize ezML’s API: Find your client_key and client_secret in Settings.


    import requests
    
    url = "https://gateway.ezml.io/api/v1/auth"
    
    payload = {
        "client_key": "your_client_key",
        "client_secret": "your_client_secret",
        "ttl": 24 # optional (default 24), hours until token expires
    }
    
    res = requests.post(url, json=payload)
    
    res.json()["access_token"] # use in Authorization header for all API requests


  • API Configuration: Use the VQA API: VQA API Documentation


    def image_to_base64(image_path: str) -> str:
        with open(image_path, "rb") as image_file:
            # Read the image, encode it in base64, and convert to string
            return base64.b64encode(image_file.read()).decode('utf-8')
    
    def test_vqa():
        url = f"https://gateway.ezml.io/api/v1/functions/visual_question_answering"
        payload = {
            "image": image_to_base64("<path to image>"),
            "prompt": "Describe this image including the make and model of each vehicle"
        }
        headers = {
            "Authorization": "Bearer <token from /auth>"
        }
    
        res = requests.post(url, json=payload, headers=headers)
        res = res.json()
    
        print(res["result"]) # print the answer to question
