AutoMix: Automatically Mixing Language Models

What is AutoMix?

The idea behind AutoMix is simple:

1. Send a query to small language model (SLM), gets a noisy label on its correctness using few-shot self-verification done with the same model (SLM).

2. Use a meta-verifier to double check verifier's output, and route the query to a larger language model (LLM) if needed.

Self-Verification and Meta-verification

At the center of automix is the idea of context-grounded self-verification:

• However, such verification can often be noisy, so we introduce an additional layer of meta-verification using POMDPs or thresholding.

Notebooks

Running inference

• Step1 Run inference to solve tasks - Task prompts, code to run inference from different language models.

Few-shot self-verification

• Step2 Self Verify - Verification prompts, code to run verification on the outputs produced in step 1.

Meta-verification

• Step3 Meta Verify - Run meta-verification using different AutoMix methods on outputs produced from Step 2.

• You can run `pip install automix-llm' to use the meta-verifier system wide.

Replicating the results

• To replicate the results in the paper, please run python scripts paper_results.py

Data and Outputs

• We experiment with 5 datasets: CNLI, CoQA, NarrativeQA, QASPER, and Quality.

• Note: The dataset are sourced from scrolls. Please cite scrolls and the appropriate sources if you use these datasets. We are making them available in a sinlge jsonl file for ease of use and reproducibility. For details on how CoQa was prepared, please see Preparing COQA.

• Inputs: All input data for the AutoMix project is provided in automix_inputs.jsonl. You can access and download it directly from Google Drive.

• Outputs from LLAMA2: The outputs generated using the LLAMA2 model are stored in automix_llama2_outputs.jsonl, available alongside the input file in the linked Google Drive.

id: A unique identifier for each question and answer pair.
pid: An additional identifier potentially mapping to specific instances or model variants.
base_ctx: The context.
question: Input question or query.
output: Ground truth.
dataset: .
llama13b_pred_ans: The answer generated by the llama13b model.
llama70b_pred_ans: The answer generated by the llama70b model.
llama13b_ver: Verification outputs of the llama13b model’s answers.
