Large-Scale Pre-Training for Goal-Directed Dialog (GODEL)

GODEL is a large-scale pre-trained model for goal-directed dialogs. It is parameterized with a Transformer-based encoder-decoder model and trained for response generation grounded in external text, which allows more effective fine-tuning on dialog tasks that require conditioning the response on information that is external to the current conversation (e.g., a retrieved document). The pre-trained model can be efficiently fine-tuned and adapted to accomplish a new dialog task with a handful of task-specific dialogs. The v1.1 model is trained on 551M multi-turn dialogs from Reddit discussion thread, and 5M instruction and knowledge grounded dialogs.

Multi-turn generation examples from an interactive environment:

Chitchat example:

Instruction: given a dialog context, you need to response empathically.
User: Does money buy happiness?
Agent: It is a question. Money buys you a lot of things, but not enough to buy happiness.
User: What is the best way to buy happiness ?
Agent: Happiness is bought through your experience and not money.

Grounded response generation example:

Instruction: given a dialog context and related knowledge, you need to response safely based on the knowledge.
Knowledge: The best Stardew Valley mods PCGamesN_0 / About SMAPI
User: My favorite game is stardew valley. stardew valley is very fun.
Agent: I love Stardew Valley mods, like PCGamesN_0 / About SMAPI.

Please find the information about preprocessing, training and full details of the GODEL in the project webpage.

How to use

Now we are ready to try out how the model works as a chatting partner!

python

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("microsoft/GODEL-v1_1-base-seq2seq")
model = AutoModelForSeq2SeqLM.from_pretrained("microsoft/GODEL-v1_1-base-seq2seq")

def generate(instruction, knowledge, dialog):
    if knowledge != '':
        knowledge = '[KNOWLEDGE] ' + knowledge
    dialog = ' EOS '.join(dialog)
    query = f"{instruction} [CONTEXT] {dialog} {knowledge}"
    input_ids = tokenizer(f"{query}", return_tensors="pt").input_ids
    outputs = model.generate(input_ids, max_length=128, min_length=8, top_p=0.9, do_sample=True)
    output = tokenizer.decode(outputs[0], skip_special_tokens=True)
    return output

# Instruction for a chitchat task
instruction = f'Instruction: given a dialog context, you need to response empathically.'
# Leave the knowldge empty
knowledge = ''
dialog = [
    'Does money buy happiness?',
    'It is a question. Money buys you a lot of things, but not enough to buy happiness.',
    'What is the best way to buy happiness ?'
]
response = generate(instruction, knowledge, dialog)
print(response)
