What does Agora mean?

In ancient Athens, the Agora was a public space where citizens would gather to debate, share news, learn from each other, and listen to famous philosophers.

We made an analogy between data generators and teachers, where different generators teach student models using synthetic data in AgoraBench!

Usage Guide 🚀

Our library is convenient for two types of audiences:

1. Testing an LM's Data Generation Capability with AgoraBench: Using the pre-built pipeline, you can easily measure the data generation capabilities of different LLMs.
2. Custom Usage: You could customize the pipeline for your own tasks to generate large amounts of synthetic data.

Testing an LM's Data Generation Capability with AgoraBench

Step 1: Generate Data with Pre-built Pipeline

You could simply run the following script:

cd "./alchemy_scripts"

python3 run.py --method "instance_generation" --domain "math" --model_name "gpt-4o-mini-2024-07-18" --max_tokens 4096 --temperature 1.0 --num_instances 10000 --num_threads 4 --api_key ""

• method should be either "instance_generation", "response_generation", or "quality_enhancement".

• domain should be either "math", "general", "code'.

• model_name should be exactly the same with how you call it on OpenAI API, LiteLLM, or vLLM.

• The resulting dataset should look as follows:

[
   {
      "config": "",
      "instruction": "",
      "response": ""
   },
   [...]
]

Step 2: Upload the dataset to huggingface

You could use the following function:

from datasets import DatasetDict

def upload_to_huggingface(data, dataset_name, hf_key):
    dataset = Dataset.from_list(data)
    dataset_dict = DatasetDict({"train": dataset})
    api = HfApi()
    dataset_dict.push_to_hub(dataset_name, token=hf_key, private=True)

Step 3: Train Student Models with Synthetic Data

The following code is modified based on Meta's llama-recipes!

First, install the required packages

cd ./llama-recipes
pip3 install -r requirements.txt
pip3 install -e .
pip3 install wandb
wandb login
huggingface-cli login

Then, launch the following code.

gpu = 4
lr = 1e-5
checkpoint_dir = ""
hf_cache_dir = ""
hf_dataset_name = ""

torchrun --nnodes 1 --nproc_per_node $gpu \
        src/llama_recipes/finetuning.py \
        --model_name meta-llama/Meta-Llama-3.1-8B \
        --dist_checkpoint_root_folder "${checkpoint_dir}" \
        --dist_checkpoint_folder "${hf_dataset_name}" \
        --hf_cache_dir "${hf_cache_dir}" \
        --dataset "$hf_dataset_name" \
        --run_validation True \
        --context_length 4096 \
        --gradient_accumulation_steps 8 \
        --batching_strategy "packing" \
        --use_fast_kernels \
        --enable_fsdp \
        --pure_bf16 \
        --low_cpu_fsdp \
        --batch_size_training 2 \
        --num_epochs $num_epochs \
        --lr $lr \
        --weight_decay 0.01 \
        --use_wandb

• You have to fill in:

  • checkpoint_dir (where the checkpoint is saved)
  • hf_cache_dir (where huggingface cache is saved)
  • hf_dataset_name (the dataset you uploaded on hf from Stage 1)

• For uploading the checkpoint to huggingface, you could refer to this code.

Step 5: Evaluate Student Models and Measure Performance Gap Recovered (PGR)

For evaluating the trained student models, we used the following libraries:

• AlpacaEval 2.0 (Instruction-following): link
• Arena-Hard (Instruction-following): link
• MBPP (Code): link
• Human-Eval (Code): link

For GSM8K (Math) and MATH (Math), we implemented our custom code: TO BE ADDED

Custom Usage

For custom usage with different pipelines, parsing mechanisms, and validation logics, Alchemy supports convenient customization through abstract classes.

Prompt Loader: A class that prepares the meta-prompt passed to the data generator.

class CustomPromptLoader(InstanceGenerationPromptLoader):
   def __init__(self, prompt_template: str, seed_data: List[Dict], num_fewshot: int, placeholder_formats: Dict[str, str] = None, num_sample_from_seed_data: Optional[int] = None, [...]):
      super().__init__(prompt_template, seed_data, num_fewshot, placeholder_formats, num_sample_from_seed_data)
      [...]
    
    def prepare(self) -> PromptResult:
      [...]
      return PromptResult(prompt=prompt, metadata=metadata)

Parser: A class that separates the instruction and response from the data generator's output.

class CustomParser(Parser):

   def parse(self, prompt, teacher_model_output, placeholder_formats, [...]):
      [...]
      return {"instruction: instruction, "response": response}

Validator: A class that determines if the output is valid or not.

class CustomValidator(Validator):
   def validate(self, instruction: str, response: str, [...]):
      [...]
      if [...]:
        return True
      else:
        return False

All together

Then, you could write a script that utilizes the custom classes to generate data.

# MODIFY THE PLACEHOLDER FORMATS BASED ON YOUR PROMPT TEMPLATE
# Demonstration related placeholders are only used for instance generation
# Input Theme place holder is an example of a custom placeholder

placeholder_formats = {
    "demonstration_input_placeholder": "<input@>",
    "demonstration_output_placeholder": "<output@>",
    "test_input_placeholder": "<input>",
    "test_output_placeholder": "<output>",
    "test_input_trigger": "INPUT:",
    "test_output_trigger": "OUTPUT:",
    "stop_phrase": "[END]",
    "input_theme": "<input_theme>",
}


with open("", "r") as f:
    seed_data = json.load(f)

with open("", "r") as f:
    prompt_template = f.read()

llm = OpenAILLM(model_name="gpt-4o-mini-2024-07-18", api_key="")

prompt_loader = CustomPromptLoader(prompt_template=prompt_template, seed_data=seed_data, num_fewshot=3, placeholder_formats=placeholder_formats, num_sample_from_seed_data=2)
parser = CustomParser()
validator = CustomValidator()


sampling_params = {
    "max_tokens": args.max_tokens,
    "temperature": args.temperature,
    "top_p": 0.9,
    "stop": placeholder_formats["stop_phrase"]
}

agora = Agora(
    llm=llm,
    placeholder_formats=placeholder_formats,
    prompt_loader=prompt_loader,
    parser=parser,
    validator=validator,
    sampling_params=sampling_params
)

# Use cache_file to resume from previous results: The Alchemy class will automatically make a cache file "final_result.jsonl" for example
result = agora.run(num_instances=10000, num_threads=16, output_file="./results/final_result.json")
print(result[0])
