Hands-on Implementations with Gemini LLM

Let’s use the Gemini LLM in some basic implementations just to understand how to utilize it in relevant applications. To get started, first you need to obtain the API key from Google’s platform. You can visit https://makersuite.google.com/app/apikey and create an API key for using Generative AI services.

Let’s implement the following steps after getting the API

1. Import the required library and setup the environment

The provided code imports the ‘google.generativeai’ module, likely associated with Google’s Generative AI capabilities, and the ‘os’ module used for interacting with the operating system in Python.

import google.generativeai as genai
import os

This snippet sets the Google API key as an environment variable named ‘GOOGLE_API_KEY’ by assigning it a specific value. The code then uses the genai.configure() function, which presumably initializes or configures the generative AI module from Google. This initialization likely involves setting up parameters or authentication required to use the Google Generative AI services using the provided API key.

# Replace with your actual API key
os.environ['GOOGLE_API_KEY'] = 'AIzaSyCs2uYa-p4LgoOCfOOxxxxxxxxxxxxxxxxxx'
genai.configure()

2. Instantiate the Gemini Pro LLM

This line of code creates an instance of a GenerativeModel object from the genai module, specifically initializing a model named ‘gemini-pro’. This model is a variant or version of the Gemini Language Model (LLM) provided by Google’s Generative AI framework. The variable model will now represent this particular instance of the generative model, allowing you to use its functionalities for text generation or other tasks.

model = genai.GenerativeModel('gemini-pro')

3. Perform simple Q&A with Gemini Pro

This section of code leverages the model object created earlier, calling its generate_content() method with the input text “Who is Sam Altman?”. This method utilizes the pre-trained Gemini Language Model (LLM) to generate text based on the provided prompt/question. The generated text or response is stored in the variable response, and response.text retrieves the actual generated text for display or further processing. In this case, it would display the text generated by the model in response to the prompt about Sam Altman.

response = model.generate_content("Who is Sam Altman?")
print(response.text)

Output:

4. Customize Question Answering process

response = model.generate_content("Tell me about OpenAI?",
                                 generation_config = genai.types.GenerationConfig(
                                 candidate_count = 1,
                                 stop_sequences = ['.'],
                                 max_output_tokens = 100,
                                 top_p = 0.6,
                                 top_k = 5,
                                 temperature = 0.1)
                               )

print(response.text)

Output:

This part of the code demonstrates a more controlled text generation process using the generate_content() method of the model object. It provides additional parameters through generation_config from genai.types.GenerationConfig.

  • candidate_count = 1: Specifies to generate only one candidate response.
  • stop_sequences = [‘.’]: Defines that text generation should halt when the model encounters a period (‘.’).
  • max_output_tokens = 100: Limits the maximum number of tokens (words or subwords) in the generated text to 100.
  • top_p = 0.6: Controls the cumulative probability for selecting tokens during generation; higher values allow more diversity.
  • top_k = 5: Narrows down token selection to the top 5 tokens with the highest probability.
  • temperature = 0.1: Governs the randomness or creativity of the generated text; lower values produce more conservative, predictable output.

This setup configures the model to generate text about OpenAI while adhering to specific constraints and preferences set by these parameters. The response.text will print the generated text based on these conditions and the given prompt about OpenAI.

5. Perform Image Based Q&A

The below code intends to utilize the model that is specialized for vision-related tasks (‘gemini-pro-vision’), provided by the genai module. The below snippet uses the PIL.Image.open() function from the Python Imaging Library (PIL) to open an image file named ‘elon musk.jpeg’. Then, it creates an instance of the vision model named vision_model. The subsequent generate_content() method call on vision_model aims to provide the model with a prompt (“Explain the picture?”) along with the image file itself as input to generate text that explains the contents or context of the given picture. Finally, response.text retrieves and prints the generated text explanation based on the image provided.

import PIL.Image
image = PIL.Image.open('/content/elon musk.jpeg')
vision_model = genai.GenerativeModel('gemini-pro-vision')
response = vision_model.generate_content(["Explain the picture?",image])
print(response.text)

Output:

6. Write a story from a given image

The below code segment leverages the genai GenerativeModel specialized for vision tasks (‘gemini-pro-vision’). It opens an image file (‘picture1.jpg’) using the Python Imaging Library (PIL) and initializes the vision model. The generate_content() method is then employed, presenting a prompt (“Write a story from the picture”) along with the image as input, prompting the model to generate a narrative or story based on the content it interprets from the provided image. The generated story is accessed through response.text, displaying the textual story created by the model based on its understanding of the image.

image = PIL.Image.open('/content/picture1.jpg')
vision_model = genai.GenerativeModel('gemini-pro-vision')
response = vision_model.generate_content(["Write a story from the picture",image])
print(response.text)
