The `gte-modernbert` series models include both text embedding models and rerank models. The `gte-modernbert` models demonstrates competitive performance in several text embedding and text retrieval evaluation tasks when compared to similar-scale models from the current open-source community. This includes assessments such as MTEB, LoCO, and COIR evaluation. ## Model Overview - Developed by: Tongyi Lab, Alibaba Group - Model Type: Text Embedding - Primary Language: English - Model Size: 149M - Max Input Length: 8192 tokens - Output Dimension: 768 ### Model list | Models | Language | Model Type | Model Size | Max Seq. Length | Dimension | MTEB-en | BEIR | LoCo | CoIR | |:--------------------------------------------------------------------------------------:|:--------:|:----------------------:|:----------:|:---------------:|:---------:|:-------:|:----:|:----:|:----:| | [`gte-modernbert-base`](https://huggingface.co./Alibaba-NLP/gte-modernbert-base) | English | text embedding | 149M | 8192 | 768 | 64.38 | 55.33 | 87.57 | 79.31 | | [`gte-reranker-modernbert-base`](https://huggingface.co./Alibaba-NLP/gte-reranker-modernbert-base) | English | text reranker | 149M | 8192 | - | - | 56.19 | 90.68 | 79.99 | ## Usage > [!TIP] > For `transformers` and `sentence-transformers`, if your GPU supports it, the efficient Flash Attention 2 will be used automatically if you have `flash_attn` installed. It is not mandatory. > > ```bash > pip install flash_attn > ``` Use with `transformers` ```python # Requires transformers>=4.48.0 import torch.nn.functional as F from transformers import AutoModel, AutoTokenizer input_texts = [ "what is the capital of China?", "how to implement quick sort in python?", "Beijing", "sorting algorithms" ] model_path = "Alibaba-NLP/gte-modernbert-base" tokenizer = AutoTokenizer.from_pretrained(model_path) model = AutoModel.from_pretrained(model_path) # Tokenize the input texts batch_dict = tokenizer(input_texts, max_length=8192, padding=True, truncation=True, return_tensors='pt') outputs = model(**batch_dict) embeddings = outputs.last_hidden_state[:, 0] # (Optionally) normalize embeddings embeddings = F.normalize(embeddings, p=2, dim=1) scores = (embeddings[:1] @ embeddings[1:].T) * 100 print(scores.tolist()) # [[42.89073944091797, 71.30911254882812, 33.664554595947266]] ``` Use with `sentence-transformers`: ```python # Requires transformers>=4.48.0 from sentence_transformers import SentenceTransformer from sentence_transformers.util import cos_sim input_texts = [ "what is the capital of China?", "how to implement quick sort in python?", "Beijing", "sorting algorithms" ] model = SentenceTransformer("Alibaba-NLP/gte-modernbert-base") embeddings = model.encode(input_texts) print(embeddings.shape) # (4, 768) similarities = cos_sim(embeddings[0], embeddings[1:]) print(similarities) # tensor([[0.4289, 0.7131, 0.3366]]) ``` Use with `transformers.js`: ```js // npm i @xenova/transformers import { pipeline, dot } from '@xenova/transformers'; // Create feature extraction pipeline const extractor = await pipeline('feature-extraction', 'Alibaba-NLP/gte-modernbert-base', { quantized: false, // Comment out this line to use the quantized version }); // Generate sentence embeddings const sentences = [ "what is the capital of China?", "how to implement quick sort in python?", "Beijing", "sorting algorithms" ] const output = await extractor(sentences, { normalize: true, pooling: 'cls' }); // Compute similarity scores const [source_embeddings, ...document_embeddings ] = output.tolist(); const similarities = document_embeddings.map(x => 100 * dot(source_embeddings, x)); console.log(similarities); ``` ## Training Details The `gte-modernbert` series of models follows the training scheme of the previous [GTE models](https://huggingface.co./collections/Alibaba-NLP/gte-models-6680f0b13f885cb431e6d469), with the only difference being that the pre-training language model base has been replaced from [GTE-MLM](https://huggingface.co./Alibaba-NLP/gte-en-mlm-base) to [ModernBert](https://huggingface.co./answerdotai/ModernBERT-base). For more training details, please refer to our paper: [mGTE: Generalized Long-Context Text Representation and Reranking Models for Multilingual Text Retrieval](https://aclanthology.org/2024.emnlp-industry.103/) ## Evaluation ### MTEB The results of other models are retrieved from [MTEB leaderboard](https://huggingface.co./spaces/mteb/leaderboard). Given that all models in the `gte-modernbert` series have a size of less than 1B parameters, we focused exclusively on the results of models under 1B from the MTEB leaderboard. | Model Name | Param Size (M) | Dimension | Sequence Length | Average (56) | Class.
