+# MultiBERTs, Intermediate Checkpoint - Seed 1, Step 1400k
+
+MultiBERTs is a collection of checkpoints and a statistical library to support
+robust research on BERT. We provide 25 BERT-base models trained with
+similar hyper-parameters as
+[the original BERT model](https://github.com/google-research/bert) but
+with different random seeds, which causes variations in the initial weights and order of
+training instances. The aim is to distinguish findings that apply to a specific
+artifact (i.e., a particular instance of the model) from those that apply to the
+more general procedure.
+
+We also provide 140 intermediate checkpoints captured
+during the course of pre-training (we saved 28 checkpoints for the first 5 runs).
+
+The models were originally released through
+[http://goo.gle/multiberts](http://goo.gle/multiberts). We describe them in our
+paper
+[The MultiBERTs: BERT Reproductions for Robustness Analysis](https://arxiv.org/abs/2106.16163).
+
+This is model #1, captured at step 1400k (max: 2000k, i.e., 2M steps).
+
+## Model Description
+
+This model was captured during a reproduction of
+[BERT-base uncased](https://github.com/google-research/bert), for English: it
+is a Transformers model pretrained on a large corpus of English data, using the
+Masked Language Modelling (MLM) and the Next Sentence Prediction (NSP)
+objectives.
+
+The intended uses, limitations, training data and training procedure for the fully trained model are similar
+to [BERT-base uncased](https://github.com/google-research/bert). Two major
+differences with the original model:
+
+*   We pre-trained the MultiBERTs models for 2 million steps using sequence
+    length 512 (instead of 1 million steps using sequence length 128 then 512).
+*   We used an alternative version of Wikipedia and Books Corpus, initially
+    collected for [Turc et al., 2019](https://arxiv.org/abs/1908.08962).
+
+This is a best-effort reproduction, and so it is probable that differences with
+the original model have gone unnoticed. The performance of MultiBERTs on GLUE after full training is oftentimes comparable to that of original
+BERT, but we found significant differences on the dev set of SQuAD (MultiBERTs outperforms original BERT).
+See our [technical report](https://arxiv.org/abs/2106.16163) for more details.
+
+### How to use
+
+Using code from
+[BERT-base uncased](https://huggingface.co/bert-base-uncased), here is an example based on
+Tensorflow:
+
+```
+from transformers import BertTokenizer, TFBertModel
+tokenizer = BertTokenizer.from_pretrained('google/multiberts-seed_1-step_1400k')
+model = TFBertModel.from_pretrained("google/multiberts-seed_1-step_1400k")
+text = "Replace me by any text you'd like."
+encoded_input = tokenizer(text, return_tensors='tf')
+output = model(encoded_input)
+```
+
+PyTorch version:
+
+```
+from transformers import BertTokenizer, BertModel
+tokenizer = BertTokenizer.from_pretrained('google/multiberts-seed_1-step_1400k')
+model = BertModel.from_pretrained("google/multiberts-seed_1-step_1400k")
+text = "Replace me by any text you'd like."
+encoded_input = tokenizer(text, return_tensors='pt')
+output = model(**encoded_input)
+```
