-
-## Hosted Inference API
-
-The easiest way to get started with Nomic Embed is through the Nomic Embedding API.
-
-Generating embeddings with the `nomic` Python client is as easy as 
-
-```python
-from nomic import embed
-
-output = embed.text(
-    texts=['Nomic Embedding API', '#keepAIOpen'],
-    model='nomic-embed-text-v1',
-    task_type='search_document'
-)
-
-print(output)
-```
-
-For more information, see the [API reference](https://docs.nomic.ai/reference/endpoints/nomic-embed-text)

-
-## Training Details
-
-We train our embedder using a multi-stage training pipeline. Starting from a long-context [BERT model](https://huggingface.co/nomic-ai/nomic-bert-2048),
-the first unsupervised contrastive stage trains on a dataset generated from weakly related text pairs, such as question-answer pairs from forums like StackExchange and Quora, title-body pairs from Amazon reviews, and summarizations from news articles.
-
-In the second finetuning stage, higher quality labeled datasets such as search queries and answers from web searches are leveraged. Data curation and hard-example mining is crucial in this stage.
-
-For more details, see the Nomic Embed [Technical Report](https://static.nomic.ai/reports/2024_Nomic_Embed_Text_Technical_Report.pdf) and corresponding [blog post](https://blog.nomic.ai/posts/nomic-embed-text-v1).
-
-Training data to train the models is released in its entirety. For more details, see the `contrastors` [repository](https://github.com/nomic-ai/contrastors)
-
-## Usage
-
-Note `nomic-embed-text` requires prefixes! We support the prefixes `[search_query, search_document, classification, clustering]`.
-For retrieval applications, you should prepend `search_document` for all your documents and `search_query` for your queries.
-
-### Sentence Transformers
-```python
-from sentence_transformers import SentenceTransformer
-
-model = SentenceTransformer("nomic-ai/nomic-embed-text-v1-unsupervised", trust_remote_code=True)
-sentences = ['search_query: What is TSNE?', 'search_query: Who is Laurens van der Maaten?']
-embeddings = model.encode(sentences)
-print(embeddings)
-```
-
-### Transformers
-```python
-import torch
-import torch.nn.functional as F
-from transformers import AutoTokenizer, AutoModel
-
-def mean_pooling(model_output, attention_mask):
-    token_embeddings = model_output[0]
-    input_mask_expanded = attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float()
-    return torch.sum(token_embeddings * input_mask_expanded, 1) / torch.clamp(input_mask_expanded.sum(1), min=1e-9)
-
-sentences = ['search_query: What is TSNE?', 'search_query: Who is Laurens van der Maaten?']
-
-tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased')
-model = AutoModel.from_pretrained('nomic-ai/nomic-embed-text-v1-unsupervised', trust_remote_code=True)
-model.eval()
-
-encoded_input = tokenizer(sentences, padding=True, truncation=True, return_tensors='pt')
-
-with torch.no_grad():
-    model_output = model(**encoded_input)
-
-embeddings = mean_pooling(model_output, encoded_input['attention_mask'])
-embeddings = F.normalize(embeddings, p=2, dim=1)
-print(embeddings)
-```
-
-The model natively supports scaling of the sequence length past 2048 tokens. To do so, 
-
-```diff
-- tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased')
-+ tokenizer = AutoTokenizer.from_pretrained('bert-base-uncased', model_max_length=8192)
-
-
-- model = AutoModel.from_pretrained('nomic-ai/nomic-embed-text-v1-unsupervised', trust_remote_code=True)
-+ model = AutoModel.from_pretrained('nomic-ai/nomic-embed-text-v1-unsupervised', trust_remote_code=True, rotary_scaling_factor=2)
-```
