RoBERTa Large fine tuned on SNLI
Model
This checkpoint is based on FacebookAI/roberta-large.
It was fine tuned on the SNLI training split.
The model predicts one of three labels:
| Label | Meaning |
|---|
| 0 | entailment |
| 1 | neutral |
| 2 | contradiction |
The input order is premise first and hypothesis second.
Evaluation
Accuracy was measured on the official SNLI validation and test splits.
| Split | Accuracy | Examples |
|---|
| Validation | 93.24% | 9,842 |
| Test | 92.44% | 9,824 |
These values are plain classification accuracy.
Comparisons should use the same SNLI splits and the same label mapping.
The machine readable results are stored in baseline_eval.json.

Limitations
The model was trained and evaluated on English SNLI data.
Performance on other NLI datasets may differ.
The model can inherit errors and biases from the base model and the training data.
The checkpoint has not been evaluated for high risk or safety critical use.
