Llama-X: Open Academic Research on Improving LLaMA to SOTA LLM

This is the repo for the Llama-X, which aims to:

• Progressively improve the performance of LLaMA to SOTA LLM with open-source community.
• Conduct Llama-X as an open academic research which is long-term, systematic and rigorous.
• Save the repetitive work of community and we work together to create more and faster increment.

The project will follow these principles:

• We will publish all the code, model, data, and experiments details.
• We will continuously improve the model version by version and open the newest method.
• We will summary the method of each main version as academic papers.
• We announce a complete research plan. The contributors are wellcome to cooperate with each other to progressively improve Llama-X through iteration of the target versions.
• The check-in of the new model must achieve significant improvement with current version on automatic evaluation.

📣 Please join if you are interested in Llama-X.

News

We have completed the training of our first version of model (Llama-X 3.0.1 7B). Please experience our model in the demo page, and the data, code and model weights of different scales will be updated in this repo later.

[1]. Research on Instruction Tuning

• instruction-following tuning

[2]. Research on RLHF & RLAIF

• fundamental RLHF
• AI learning from AI

[3]. Research on Data Quality

[4]. Research on Long Context Transformer

• enable efficient transformers for long sequence (>30k)

[5]. Research on Multi-modal (text + image) Modeling

Llama-X Model Version

Llama-X	Baseline	Performance
3.0.0 (LLaMA)	GPT-3	Outperform
3.1.0	text-davinci-001	Comparable
3.2.0	text-davinci-002	Comparable
3.3.0	text-davinci-003	Comparable

We are focusing on the above research areas [1] & [3] now, and would public our first version of model (Llama-X 3.0.1) and paper.

Llama-X Evaluation

Each new version of Llama-X model should significantly outperform (+>1%) the current version model on the automatic evaluation of all the following Type-A benchmarks. And the additional evaluation for Type-B benchmarks should be added in the 3.6.0+ versions:

Type	Benchmarks
A	MMLU
A	HumanEval
A	GSM-8K
A	NaturalQuestions
A	TruthfulQA
B	Leetcode
B	GRE
B	AP
B	MMLU-Multilingual
B	Visual Inputs (TBD)

Results:

Model	MMLU	TruthfulQA	GSM-8K	NaturalQuestions
InstructGPT davinci v2 (175B)^	0.57	0.62	0.35	0.389
Llama-X 3.0.1 (7B)	0.4412	0.2032	0.1887	0.2422
Llama-i (7B)	0.5121	0.2142	0.2259	0.3499

How to contribute

Developers can become Contributors by contributing helpful code, data, paper and computing resource, etc.

1. Code: Including algorithm implementation, training optimization, inference optimization, and model deployment.

2. Data: Every research area and version iteration requires high-quality data, including instruction-answer, pre-training, multi-modal, multilingual, and user feedbacks data, etc.

3. Paper: We will maintain a Llama-X Paper List, and use Llama-X as the base model for optimized, fully tested, and significantly improved academic papers. You can check in to the Llama X Paper List.

4. Computing resource: We hope to help accelerate model iteration speed by coordinating redundant computing power from some developers or non-profit sponsorship from universities/enterprises.
