Llama-3.2-8b used in the course and lab -- does it exist within meta-llama repo?

Hello team,

I’m looking into utils.py to understand the code. I noticed that llama-3.2-8b is referenced, but I wasn’t able to find a matching model in the meta-llama repo.

The model was called here within the lab notebook:

Load error analysis model from utils

ERROR_CATEGORIES = [
“calculation_error”, # Math computation mistakes
“reasoning_error”, # Logical reasoning issues
“incomplete_solution”, # Partial or unfinished answers
“format_error”, # Wrong answer format
“other” # Other errors
]

tokenizer, model, hf_model_available = load_error_analysis_model()

I then looked into load_error_analysis_model() in utils.py:

def load_error_analysis_model():
“”"
Load the error analysis model from local disk.
Returns:
tuple: (tokenizer, model, hf_model_available) where hf_model_available is bool
“”"
print(“Loading local model for error analysis…”)
try:

local_model_path = ‘/app/models/llama-3.2-8b’

    # Verify the model directory exists
    if not os.path.exists(local_model_path):
        raise FileNotFoundError(f"Model directory not found at: {local_model_path}")
    
    if not os.path.isdir(local_model_path):
        raise NotADirectoryError(f"Path exists but is not a directory: {local_model_path}")
    
    print(f"📦 Loading model from: {local_model_path}")
    
    # Load tokenizer from local path only
    print("Loading tokenizer...")
    tokenizer = AutoTokenizer.from_pretrained(
        local_model_path,
        local_files_only=True,
        trust_remote_code=True
    )

It appears llama-3.2-8b is the model being loaded. However, after checking Meta-llama repo on huggingface ( meta-llama (Meta Llama) ), I wasn’t able to locate a matching model – I may be looking in the wrong place. There is a mradermacher/Llama-3.2-8B-Instruct-GGUF · Hugging Face , but it looks different from the model used in this course and lab.

Questions for the instructor / community

  1. Could llama-3.2-8b be a typo, or am I missing something about where this model is hosted? Or, should it be llama-3.1-8b or llama-3-8b?

  2. What checkpoint was the course originally validated against? (Could you share the exact HuggingFace model ID or expected directory contents — e.g., does it contain tokenizer.json, tokenizer.model, or both?)

Thanks in advances!
