# Uni-ColBERTer (Dim: 1) for Passage Retrieval
|

If you want to know more about our (Uni-)ColBERTer architecture check out our paper: https://arxiv.org/abs/2203.13088 🎉

## Limitations & Bias
|
19 |
+
|
20 |
+
- The model is only trained on english text.
|
21 |
+
|
22 |
+
- The model inherits social biases from both DistilBERT and MSMARCO.
|
23 |
+
|
24 |
+
- The model is only trained on relatively short passages of MSMARCO (avg. 60 words length), so it might struggle with longer text.
