Chatqa
Overview :
ChatQA is a series of conversational question answering (QA) models that can achieve GPT-4 level accuracy. We propose a two-stage instruction tuning method that can significantly improve the zero-shot conversational QA results of large language models (LLMs). To handle retrieval in dialogue-based QA, we fine-tuned dense retrievers on multi-turn QA datasets, which provides comparable results to using state-of-the-art query rewrite models while significantly reducing deployment costs. Notably, our ChatQA-70B outperforms GPT-4 (54.14 vs. 53.90) on the average score across 10 conversational QA datasets without relying on any synthetic data from the OpenAI GPT model.
Target Users :
ChatQA can be used to build high-accuracy conversational question answering systems, suitable for various dialogue-based application scenarios.
Use Cases
Use ChatQA in intelligent customer service systems to provide more accurate answers.
Build intelligent assistant applications with more natural conversational capabilities.
Used in online education platforms to provide more intelligent question-and-answer interaction.
Features
Construct GPT-4 level conversational question answering models
Provide a two-stage instruction tuning method
