+# TeenyTinyLlama-460m-HateBR
+
+TeenyTinyLlama is a series of small foundational models trained in Brazilian Portuguese.
+
+This repository contains a version of [TeenyTinyLlama-460m](https://huggingface.co/nicholasKluge/TeenyTinyLlama-160m) (`TeenyTinyLlama-460m-HateBR`) fine-tuned on the [HateBR dataset](https://huggingface.co/datasets/ruanchaves/hatebr).
+
+## Details
+
+- **Number of Epochs:** 3
+- **Batch size:** 16
+- **Optimizer:** `torch.optim.AdamW` (learning_rate = 4e-5, epsilon = 1e-8)
+- **GPU:** 1 NVIDIA A100-SXM4-40GB
+
+## Usage
+
+Using `transformers.pipeline`:
+
+```python
+from transformers import pipeline
+
+text = "Pega a sua opinião e vai a merda com ela!"
+
+classifier = pipeline("text-classification", model="nicholasKluge/TeenyTinyLlama-460m-HateBR")
+classifier(text)
+
+# >>> [{'label': 'TOXIC', 'score': 0.9998729228973389}]
+```
+
+## Reproducing
+
+To reproduce the fine-tuning process, use the following code snippet:
+
+```python
+
+# Hatebr
+! pip install transformers datasets evaluate accelerate -q
+
+import evaluate
+import numpy as np
+from huggingface_hub import login
+from datasets import load_dataset, Dataset, DatasetDict
+from transformers import AutoTokenizer, DataCollatorWithPadding
+from transformers import AutoModelForSequenceClassification, TrainingArguments, Trainer
+
+# Load the task
+dataset = load_dataset("ruanchaves/hatebr")
+
+# Format the dataset
+train = dataset['train'].to_pandas()
+train = train[['instagram_comments', 'offensive_language']]
+train.columns = ['text', 'labels']
+train.labels = train.labels.astype(int)
+train = Dataset.from_pandas(train)
+
+test = dataset['test'].to_pandas()
+test = test[['instagram_comments', 'offensive_language']]
+test.columns = ['text', 'labels']
+test.labels = test.labels.astype(int)
+test = Dataset.from_pandas(test)
+
+dataset = DatasetDict({
+    "train": train,  
+    "test": test                  
+})
+
+# Create a `ModelForSequenceClassification`
+model = AutoModelForSequenceClassification.from_pretrained(
+    "nicholasKluge/TeenyTinyLlama-460m", 
+    num_labels=2, 
+    id2label={0: "NONTOXIC", 1: "TOXIC"}, 
+    label2id={"NONTOXIC": 0, "TOXIC": 1}
+)
+
+tokenizer = AutoTokenizer.from_pretrained("nicholasKluge/TeenyTinyLlama-460m")
+
+# Preprocess the dataset
+def preprocess_function(examples):
+    return tokenizer(examples["text"], truncation=True)
+
+dataset_tokenized = dataset.map(preprocess_function, batched=True)
+
+# Create a simple data collactor
+data_collator = DataCollatorWithPadding(tokenizer=tokenizer)
+
+# Use accuracy as evaluation metric
+accuracy = evaluate.load("accuracy")
+
+# Function to compute accuracy
+def compute_metrics(eval_pred):
+    predictions, labels = eval_pred
+    predictions = np.argmax(predictions, axis=1)
+    return accuracy.compute(predictions=predictions, references=labels)
+
+# Define training arguments
+training_args = TrainingArguments(
+    output_dir="checkpoints",
+    learning_rate=4e-5,
+    per_device_train_batch_size=16,
+    per_device_eval_batch_size=16,
+    num_train_epochs=3,
+    weight_decay=0.01,
+    evaluation_strategy="epoch",
+    save_strategy="epoch",
+    load_best_model_at_end=True,
+    push_to_hub=True,
+    hub_token="your_token_here",
+    hub_model_id="username/model-ID",
+)
+
+# Define the Trainer
+trainer = Trainer(
+    model=model,
+    args=training_args,
+    train_dataset=dataset_tokenized["train"],
+    eval_dataset=dataset_tokenized["test"],
+    tokenizer=tokenizer,
+    data_collator=data_collator,
+    compute_metrics=compute_metrics,
+)
+
+# Train!
+trainer.train()
+
+```
