FoodExtract-v1

This is a food and drink extraction language model built on Gemma 3 270M.

Given raw text, it's designed to:

1. Classify the text into food or drink (e.g. "a photo of a dog" = not food or drink, "a photo of a pizza" = food or drink).
2. Tag the text with one or more tags (see tags_dict below).
3. Extract the edible food-related items as a list.
4. Extract the edible drink-related items as a list.

For example, the input text might be:

British Breakfast with baked beans, fried eggs, black pudding, sausages, bacon, mushrooms, a cup of tea and toast and fried tomatoes

And the model will generate:

food_or_drink: 1
tags: fi, di
foods: British Breakfast, baked beans, fried eggs, black pudding, sausages, bacon, mushrooms, toast, fried tomatoes
drinks: tea

This model can be used for filtering a large image caption (e.g. DataComp-1B) text dataset for food and drink related items.

Dataset

The model was trained on the FoodExtract-1k dataset.

This dataset contains 1400 samples of raw text and JSON output pairs of structured food extractions provided by gpt-oss-120b.

For example, a raw image caption input might be:

another optional quest takes place on windfall island during the night time play the song of passing a number of times and each time, glance towards the sky

And the gpt-oss-120b generated output (JSON) would be:

{'is_food_or_drink': 'false', 'tags': [], 'food_items': [], 'drink_items': []}

This is condensed to:

food_or_drink: 0\ntags: \nfoods: \ndrinks:

Tags dictionary mapping

These tags are designed for fast filtering.

For example, the model can assign a certain tag based on what's in the raw text and then we can filter for "ingredient list" items.

tags_dict = {'np': 'nutrition_panel',
 'il': 'ingredient list',
 'me': 'menu',
 're': 'recipe',
 'fi': 'food_items',
 'di': 'drink_items',
 'fa': 'food_advertistment',
 'fp': 'food_packaging'}

Helper functions

The model is trained to output a condensed version of the structured data.

We do this so the model can generate less tokens (e.g. it doesn't have to generate JSON outputs).

The following functions help to condense and uncondense raw text outputs/inputs into the desired structure.

def condense_output(original_output):
    '''Helper function to condense a given FoodExtract string.
    
    Example input: {'is_food_or_drink': True, 'tags': ['fi'], 'food_items': ['cape gooseberries', 'mulberry', 'chilli powder', 'flathead lobster', 'hoisin sauce', 'duck leg', 'chestnuts', 'raw quail', 'duck breast', 'rogan josh curry sauce', 'brown rice', 'dango'], 'drink_items': []}

    condensed_output_string_formatted = condensed_output_string_base.replace("<is_food_or_drink>", is_food_or_drink).replace("<output_tags>", tags).replace("<food_items>", foods).replace("<drink_items>", drinks)

    return condensed_output_string_formatted.strip()

Quick start

from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline

MODEL_PATH = "mrdbourke/FoodExtract-gemma-3-270m-fine-tune-v1"

# Load the model into a pipeline
loaded_model = AutoModelForCausalLM.from_pretrained(
    pretrained_model_name_or_path=MODEL_PATH,
    dtype="auto",
    device_map="auto",
    attn_implementation="eager"
)

# Load the tokenizer
tokenizer = AutoTokenizer.from_pretrained(
    pretrained_model_name_or_path=MODEL_PATH,
)

# Create model pipeline
loaded_model_pipeline = pipeline("text-generation",
                                 model=loaded_model,
                                 tokenizer=tokenizer)

# Create a sample to predict on
input_text = "A plate with bacon, eggs and toast on it"
input_text_user = [{'content': input_text, 'role': 'user'}]

# Apply the chat template
input_prompt = loaded_model_pipeline.tokenizer.apply_chat_template(conversation=input_text_user,
                                                                    tokenize=False,
                                                                    add_generation_prompt=True)

# Let's run the default model on our input
default_outputs = loaded_model_pipeline(text_inputs=input_prompt, 
                                        max_new_tokens=256)

# View the outputs
print(f"[INFO] Test sample input:\n{input_prompt}\n")
print(f"[INFO] Fine-tuned model output:\n{default_outputs[0]['generated_text'][len(input_prompt):]}\n")

You should see an output similar to:

[INFO] Test sample input:
<bos><start_of_turn>user
A plate with bacon, eggs and toast on it<end_of_turn>
<start_of_turn>model

[INFO] Fine-tuned model output:
food_or_drink: 1
tags: fi
foods: bacon, eggs, toast
