+
+<!-- Provide a quick summary of what the model is/does. -->
+
+The `boltuix/bert-pro` model is a high-performance BERT variant designed for natural language processing tasks requiring maximum accuracy. Pretrained on English text using masked language modeling (MLM) and next sentence prediction (NSP) objectives, it is optimized for fine-tuning on complex NLP tasks such as sequence classification, token classification, and question answering. With a size of ~420 MB, it prioritizes top-tier performance over resource efficiency.
+
+## Model Details
+
+### Model Description
+
+<!-- Provide a longer summary of what this model is. -->
+
+The `boltuix/bert-pro` model is a PyTorch-based transformer model derived from TensorFlow checkpoints in the Google BERT repository. It builds on research from *On the Importance of Pre-training Compact Models* ([arXiv](https://arxiv.org/abs/1908.08962)) and *Generalization in NLI: Ways (Not) To Go Beyond Simple Heuristics* ([arXiv](https://arxiv.org/abs/1908.08962)). Ported to Hugging Face, this uncased model (~420 MB) is engineered for applications demanding the highest accuracy, such as advanced NLI tasks, sentiment analysis, and question answering, making it ideal for enterprise-grade NLP solutions.

+
+## Uses
+
+<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->
+
+### Direct Use
+
+The model can be used directly for masked language modeling or next sentence prediction tasks, such as predicting missing words in sentences or determining sentence coherence, delivering high accuracy in these core tasks.
+
+### Downstream Use
+
+The model is designed for fine-tuning on high-stakes downstream NLP tasks, including:
+- Sequence classification (e.g., sentiment analysis, intent detection)
+- Token classification (e.g., named entity recognition, part-of-speech tagging)
+- Question answering (e.g., extractive QA, reading comprehension)
+- Natural language inference (e.g., MNLI, RTE)
+It is recommended for researchers, data scientists, and enterprises requiring state-of-the-art performance in NLP applications.
+
+### Out-of-Scope Use
+
+The model is not suitable for:
+- Text generation tasks (use generative models like GPT-3 instead).
+- Non-English language tasks without significant fine-tuning.
+- Ultra-low-latency or resource-constrained environments (use `boltuix/bert-micro` or `boltuix/bert-mid` instead).
+
+## Bias, Risks, and Limitations
+
+<!-- This section is meant to convey both technical and sociotechnical limitations. -->
+
+The model may inherit biases from its training data (BookCorpus and English Wikipedia), potentially reinforcing stereotypes, such as gender or occupational biases. For example:
+```python
+from transformers import pipeline
+unmasker = pipeline('fill-mask', model='boltuix/bert-pro')
+unmasker("The man worked as a [MASK].")
+```
+**Output**:
+```json
+[
+  {'sequence': '[CLS] the man worked as a engineer. [SEP]', 'token_str': 'engineer'},
+  {'sequence': '[CLS] the man worked as a doctor. [SEP]', 'token_str': 'doctor'},
+  ...
+]
+```
+```python
+unmasker("The woman worked as a [MASK].")
+```
+**Output**:
+```json
+[
+  {'sequence': '[CLS] the woman worked as a teacher. [SEP]', 'token_str': 'teacher'},
+  {'sequence': '[CLS] the woman worked as a nurse. [SEP]', 'token_str': 'nurse'},
+  ...
+]
+```
+These biases may propagate to downstream tasks. Due to its size (~420 MB), the model requires significant computational resources, making it less suitable for edge devices without optimization.
+
+### Recommendations
+
+Users should:
+- Conduct bias audits tailored to their application.
+- Fine-tune with diverse, representative datasets to reduce bias.
+- Apply model compression techniques (e.g., quantization, pruning) for resource-constrained deployments.
+
+## How to Get Started with the Model
