The Three Models in the LLaMA 4 Series: Scout, Maverick, and Behemoth
LLaMA 4 introduces three distinct models, each catering to different needs and use cases:
1. Scout:
- Active Parameters: 17B
- Total Parameters: 109B
- Context Window: Up to 10 million tokens
- Optimized for: Handling extremely long contexts (ideal for research, analyzing large texts, and multi-document processing).
2. Maverick:
- Active Parameters: 17B
- Total Parameters: 400B
- Context Window: Up to 1 million tokens
- Optimized for: Heavy-lifting tasks, including high-performance applications in NLP, coding, and reasoning.
3. Behemoth (upcoming):
- Active Parameters: Estimated at ~2 trillion (still unreleased)
- Expected Focus: The largest variant, intended for even more demanding AI tasks, with massive parameter sets for advanced use cases.
These models bring a mix of performance, memory, and efficiency, so you can choose the one that best fits your needs, whether you’re handling lengthy text, seeking higher raw performance, or looking for something more experimental with Behemoth.

How to Use LLaMA 4
To get started with LLaMA 4, follow these simple steps:
1. Installation and Setup:
- Install the required libraries:
Pyhton
pip install transformers accelerate torch
2. Code Snippets for Inference: Here’s a simple Python snippet to get started:
Python
from transformers import AutoTokenizer, AutoModelForCausalLM
model_id = "meta-llama/Llama-4-Scout-17B-16E-Instruct"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(model_id)
model = model.to("cuda")
prompt = "Explain about the Bangalore traffic in simple terms."
inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=200)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))Fine-Tuning and Customization
