+# all-MiniLM-L6-v2-nli
+
+- **Base Model:** [sentence-transformers/all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2)
+- **Task:** Natural Language Inference (NLI)
+- **Framework:** Hugging Face Transformers, Sentence Transformers
+
+all-MiniLM-L6-v2-nli is a fine-tuned NLI model that classifies the relationship between pairs of sentences into three categories: entailment, neutral, and contradiction. It enhances the capabilities of [sentence-transformers/all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2) for improved performance on NLI tasks.
+
+## Intended Use
+all-MiniLM-L6-v2-nli is ideal for applications requiring understanding of logical relationships between sentences, including:
+
+- Semantic textual similarity
+- Question answering
+- Dialogue systems
+- Content moderation
+
+## Performance
+all-MiniLM-L6-v2-nli was trained on the [sentence-transformers/all-nli](https://huggingface.co/datasets/sentence-transformers/all-nli) dataset, achieving competitive results in sentence pair classification.
+
+Performance on the MNLI matched validation set:

+## Usage Instructions
+
+## Using Sentence Transformers
+```python
+from sentence_transformers import CrossEncoder
+
+model_name = "agentlans/all-MiniLM-L6-v2-nli"
+model = CrossEncoder(model_name)
+scores = model.predict(
+    [
+        ("A man is eating pizza", "A man eats something"),
+        (
+            "A black race car starts up in front of a crowd of people.",
+            "A man is driving down a lonely road.",
+        ),
+    ]
+)
+
+label_mapping = ["entailment", "neutral", "contradiction"]
+labels = [label_mapping[score_max] for score_max in scores.argmax(axis=1)]
+print(labels)
+# Output: ['entailment', 'contradiction']
+```
+
+## Using Transformers Library
+```python
+from transformers import AutoTokenizer, AutoModelForSequenceClassification
+import torch
+
+model_name = "agentlans/all-MiniLM-L6-v2-nli"
+model = AutoModelForSequenceClassification.from_pretrained(model_name)
+tokenizer = AutoTokenizer.from_pretrained(model_name)
+
+features = tokenizer(
+    [
+        "A man is eating pizza",
+        "A black race car starts up in front of a crowd of people.",
+    ],
+    ["A man eats something", "A man is driving down a lonely road."],
+    padding=True,
+    truncation=True,
+    return_tensors="pt",
+)
+
+model.eval()
+with torch.no_grad():
+    scores = model(**features).logits
+    label_mapping = ["entailment", "neutral", "contradiction"]
+    labels = [label_mapping[score_max] for score_max in scores.argmax(dim=1)]
+    print(labels)
+# Output: ['entailment', 'contradiction']
+```
+
+## Limitations and Ethical Considerations
+all-MiniLM-L6-v2-nli may reflect biases present in the training data. Users should evaluate its performance in specific contexts to ensure fairness and accuracy.
+
+## Conclusion
+all-MiniLM-L6-v2-nli offers a robust solution for NLI tasks, enhancing [sentence-transformers/all-MiniLM-L6-v2](https://huggingface.co/sentence-transformers/all-MiniLM-L6-v2)'s capabilities with straightforward integration into existing frameworks. It aids developers in building intelligent applications that require nuanced language understanding.
