What is LightGPT?

Introducing LightGPT-instruct-6B, a language model meticulously developed by AWS Contributors and based on GPT-J 6B. This innovative model has undergone fine-tuning using the OIG-small-chip2 instruction dataset, which comprises approximately 200K training examples and falls under the Apache-2.0 license. Category Prompts:
1. Model Capabilities – LightGPT-instruct-6B is perfectly designed to generate text in response to prompts containing specific instructions, adhering to a standardized format. The model intelligently recognizes the completion of its response when the input prompt concludes with the token “### Response:n”. Focused specifically on English conversations, it thrives in this linguistic domain.
2. Deployment and Example Code – Amazon SageMaker proudly supports the deployment of the LightGPT-instruct-6B model.

Comprehensive documentation is provided, complete with example code, illustrating the seamless deployment process.
3. Evaluation Metrics – A variety of metrics are utilized to evaluate the model’s performance. These include LAMBADA PPL (perplexity), LAMBADA ACC (accuracy), WINOGRANDE, HELLASWAG, PIQA, and GPT-J.
4. Limitations – The documentation transparently addresses certain limitations of LightGPT-instruct-6B. These encompass occasional struggles with accurately following long instructions, providing incorrect answers to math and reasoning questions, and generating false or misleading responses. Additionally, the model lacks contextual understanding and solely generates responses based on the given prompt.
5. Use Cases – As a natural language generation tool, LightGPT-instruct-6B is adept at generating responses to a diverse array of conversational prompts, especially those necessitating specific instructions.
