FLAN-T5 Conversation Generator (LoRA)

This model generates call center conversations from summaries.

Model Description

• Base Model: google/flan-t5-base
• Fine-tuning: LoRA (Low-Rank Adaptation)
• Task: Summary → Conversation generation

Usage

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
from peft import PeftModel

# Load model
tokenizer = AutoTokenizer.from_pretrained("google/flan-t5-base")
base_model = AutoModelForSeq2SeqLM.from_pretrained("google/flan-t5-base")
model = PeftModel.from_pretrained(base_model, "YOUR_USERNAME/flan-t5-conversation-generator")

# Generate
prefix = "Generate a call center conversation from this summary: "
summary = "The client called about a broken AC unit. The agent scheduled a technician."

inputs = tokenizer(prefix + summary, return_tensors="pt", max_length=256, truncation=True)
outputs = model.generate(**inputs, max_new_tokens=512, num_beams=4)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
