LightGPT-instruct-6B: AI Language Model by AWS Contributors
Overview: LightGPT-instruct-6B is an AI language model developed by AWS Contributors, based on GPT-J 6B. It has been fine-tuned on the OIG-small-chip2 instruction dataset, which contains approximately 200K training examples and is licensed under Apache-2.0.
Model Capabilities: This model is designed to generate text in response to prompts containing specific instructions in a standardized format. It recognizes the completion of its response when the input prompt ends with the token "### Response:\n". The model is specifically trained for English conversations.
Deployment & Example Code: Amazon SageMaker supports the deployment of the LightGPT-instruct-6B model, and the documentation provides example code to illustrate the process.
Evaluation Metrics: The model's performance is assessed using various metrics, such as LAMBADA PPL (perplexity), LAMBADA ACC (accuracy), WINOGRANDE, HELLASWAG, PIQA, and GPT-J.
Limitations: The documentation outlines some limitations of the model, including struggles with accurately following long instructions, providing incorrect answers to math and reasoning questions, and occasionally generating false or misleading responses. The model also lacks contextual understanding and generates responses solely based on the given prompt.
Use Case: LightGPT-instruct-6B is a versatile natural language generation tool suitable for generating responses to a broad range of conversational prompts, including those requiring specific instructions.
