Model Description

Graphix-T5 is a graph-aware semi-pretrained text-to-text PLM specifically designed to improve multi-hop reasoning for the complex text-to-SQL task. This novel architecture enhances the structural encoding capabilities of the T5 model while preserving its powerful contextual encoding ability. The experimental results demonstrate the effectiveness of GRAPHIX-T5 and underscore the importance of incorporating structural information in text-to-text PLMs for tackling intricate text-to-SQL challenges. The smaller gap in performance between the dev and test sets indicates the stronger generalization capability of Graphix-T5.

Training Data

Graphix-3B is trained based on SPIDER, a cross-domain text-to-SQL benchmark. And it's evaluated in vanilla SPIDER dev, test, and other variants: SPIDER-SYN, SPIDER-DK, SPIDER-REALISTIC without additional training. This model will continue to be fine-tuned on more complex text-to-SQL data, i.e. BIRD to deal with harder but more real applications

To Begin With

You can use this model directly with a pipeline for text generation. This example generates a different sequence each time it's run:

from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained("patrickNLP/Graphix-3B")

model = AutoModel.from_pretrained("patrickNLP/Graphix-3B")


Graphix-3B w/ Picard maintains state-of-the-art (SOTA) semantic parsing capabilities, as demonstrated by its performance on the SPIDER leaderboard. Its only submission achieves 74.0% on EM and 77.6% on EX in the testing dataset. Please see Graphix Official Implementation for details.
