mistral7b-de-tokenizer-swap-mixed-bf16

Mistral-7B-v0.1 adapted to German as part of our study on efficient language adaptation: "Language Adaptation on a Tight Academic Compute Budget: Tokenizer Swapping Works and Pure bfloat16 Is Enough".

Paper: https://openreview.net/forum?id=VYfJaHeVod

Usage

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("konstantindobler/mistral7b-de-tokenizer-swap-mixed-bf16")
model = AutoModelForCausalLM.from_pretrained("konstantindobler/mistral7b-de-tokenizer-swap-mixed-bf16")

# Use model and tokenizer as usual

Details

The model is based on Mistral-7B-v0.1 and was adapted to German. The original tokenizer was replaced by a language-specific German tokenizer with a vocabulary of 32768 tokens. The new embeddings were initialized with FOCUS. The model was then trained on 8 billion German tokens from oscar-corpus/OSCAR-2301 with mixed precision (bfloat16). More details and hyperparameters can be found in the paper.

Disclaimer

The web-scale dataset used for pretraining and tokenizer training (oscar-corpus/OSCAR-2301) might contain personal and sensitive information. Such behavior needs to be assessed carefully before any real-world deployment of the models.
