This repository contains the official checkpoint for [Reinforcement Learning From Human Feedback with Macro Actions (MA-RLHF)](https://arxiv.org/pdf/2410.02743). 

## Model Description

MA-RLHF is a novel framework that integrates macro actions into conventional RLHF. The macro actions are sequences of tokens or higher-level language constructs, with can be computed through different defined termination conditions, like n-gram based, perplexity-based, or parsing-based termination conditions. By introducing macro actions into RLHF, we reduce the number of decision points and shorten decision trajectories, alleviating the credit assignment problem caused by long temporal distances.

## Model Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_path = "baidu/HH-RLHF-Gemma-7B-MA-PPO-Fixed5"

tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True)

model = AutoModelForCausalLM.from_pretrained(model_path, device_map="auto", torch_dtype='auto', trust_remote_code=True)

input_text = """
Human: Would you be able to explain the differences between the Spanish
and Italian language? Assistant: Of course. Can you tell me more about
the specific areas where you’re interested in knowing more? Human: I’m
thinking between the Spanish spoken in Mexico and Italian spoken in Italy.
Assistant: 
"""

input_ids = tokenizer(input_text, return_tensors='pt').to(model.device)
output_ids = model.generate(**input_ids, max_new_tokens=20)
response = tokenizer.decode(output_ids[0], skip_special_tokens=True)

print(response)
