+# Flan-T5 News Article Generator
+This project fine-tunes a Flan-T5 model to generate news articles in Dhivehi language based on titles.
+# Evaluation
+The model was evaluated using ROUGE metrics on a validation set. Here are the final evaluation results:
+- Loss: 0.154
+- ROUGE-1: 0.170
+- ROUGE-2: 0.135
+- ROUGE-L: 0.169
+- ROUGE-Lsum: 0.169
+The training metrics at epoch 4.35:
+- Training loss: 0.857
+- Gradient norm: 0.202
+- Learning rate: 0.000287
+The model shows reasonable performance on the validation set with ROUGE scores indicating decent overlap between generated and reference texts. The relatively low validation loss of 0.154 compared to training loss suggests the model is generalizing well without overfitting.
+# Usage
+```python
+from transformers import T5ForConditionalGeneration, T5Tokenizer
+# Load your finetuned model
+model = T5ForConditionalGeneration.from_pretrained("alakxender/flan-t5-corpora-mixed")
+tokenizer = T5Tokenizer.from_pretrained("alakxender/flan-t5-corpora-mixed")
+def generate_text(prompt, max_new_tokens=150, num_beams=1, repetition_penalty=1.2, no_repeat_ngram_size=1, do_sample=True):
+    inputs = tokenizer(prompt, return_tensors="pt")
+    outputs = model.generate(
+        **inputs,
+        max_new_tokens=max_new_tokens,
+        num_beams=num_beams,
+        repetition_penalty=repetition_penalty,
+        no_repeat_ngram_size=no_repeat_ngram_size,
+        do_sample=do_sample,
+        early_stopping=True # this flag is only used in beam-based generation modes. You should set `num_beams>1` or unset `early_stopping`
+    )
+    output_text = tokenizer.decode(outputs[0], skip_special_tokens=True)
+    # Trim to the last period
+    if '.' in output_text:
+        last_period = output_text.rfind('.')
+        output_text = output_text[:last_period+1]
+    return output_text
+prompt = "ބައެއް ފިހާރަތަކުގައި އަދިވެސް ބިދޭސީ ސޭޓުން!"
+output = generate_text(f"Create an article about: {prompt}")
+print(output)
