It has been fine-tuned on a large dataset of grammar correction examples to help improve text quality by fixing grammatical errors, punctuation, spelling, and other language issues.</p> <p>The model uses a specialized chat template that structures inputs as "text" and outputs as "corrected" to maintain a clear distinction between original and corrected content.</p> <h3>Model Details</h3> <div class="model-meta"> <p><strong>Developed by:</strong> qingy2024</p> <p><strong>Finetuned from model:</strong> <a href="https://huggingface.co/unsloth/gemma-3-1b-pt">unsloth/gemma-3-1b-pt</a> <p><strong>Model type:</strong> Gemma 3</p> <p><strong>Language(s):</strong> English</p> <p><strong>License:</strong> apache-2.0</p> <p><strong>Training Dataset:</strong> <a href="https://huggingface.co/datasets/qingy2024/grmr-v4-60k">qingy2024/grmr-v4-60k</a></p> </div> <hr> <h2>Manual Testing Examples</h2> <p>Here are a few examples of grammar corrections this model can handle:</p> <table> <thead> <tr> <th>Original Text</th> <th>Corrected Text</th> </tr> </thead> <tbody> <tr> <td>i dont know weather to bring a umbrella today</td> <td>I don't know whether to bring an umbrella today.</td> </tr> <tr> <td>she go to the store yesterday</td> <td>She went to the store yesterday.</td> </tr> <tr> <td>they is going to be late for the meeting</td> <td>They are going to be late for the meeting.</td> </tr> <tr> <td>the cat laying on the floor all day</td> <td>The cat is laying on the floor all day.</td> </tr> </tbody> </table> <hr> <h2>Training procedure</h2> <p>The model was fine-tuned using full parameter fine-tuning (not LoRA) on the GRMR-V4-60K dataset.
