InsTag: A Tool for Data Analysis in LLM Supervised Fine-tuning

We introduce a tool named InsTag for analyzing supervised fine-tuning (SFT) data in LLM aligning with human preference. For local tagging deployment, we release InsTagger, fine-tuned on InsTag results, to tag the queries in SFT data. Through the scope of tags, we sample a 6K subset of open-resourced SFT data to fine-tune LLaMA and LLaMA-2 and the fine-tuned models TagLM-13B-v1.0 and TagLM-13B-v2.0 outperform many open-resourced LLMs on MT-Bench.

What is InsTag?

Foundation language models obtain the instruction-following ability through supervised fine-tuning (SFT). Diversity and complexity are considered critical factors of a successful SFT dataset, while their definitions remain obscure and lack quantitative analyses. In this work, we propose InsTag, an open-set fine-grained tagger, to tag samples within SFT datasets based on semantics and intentions and define instruction diversity and complexity regarding tags. We obtain 6.6K tags to describe comprehensive user queries. We analyze popular open-sourced SFT datasets and find that the model ability grows with more diverse and complex data. Based on this observation, we propose a data selector based on InsTag to select 6K diverse and complex samples from open-source datasets and fine-tune models on InsTag-selected data. These models outperform open-source models based on considerably larger SFT data evaluated by MT-Bench, echoing the importance of query diversity and complexity.

InsTagger

InsTagger is a LLaMa-2 based SFT model trained with FastChat in the vicuna template. You can easily download weight at HuggingFace ModelHub and then use FastChat to serve or inference. Demo codes are about to be released.

Model Checkpoints

• InsTagger for local query tagging:

  InsTagger is an tagging LLM which is fine-tuned on InsTag's tagging results on open-resourced SFT data. The model is based on 7B version LLaMA-2.

• TagLM, fine-tuned on our SFT data sub-sampled by complexity-first diverse sampling procedure:

  With only 6k data from current open-resourced SFT dataset, TagLM can outperform many open-resourced LLMs on MT-Bench using GPT-4 as a judge.
