# kgrammar-2-1b kgrammar-2-1b is a state-of-the-art model designed to evaluate Korean sentences, particularly focusing on identifying instances where the response deviates by using a different language or mixing multiple languages within a sentence. The model is based on the gemma-2-9b architecture and aims to provide accurate assessments for language consistency and clarity in Korean text. ## Model Details - **Model Name**: kgrammar-2-1b - **Base Model**: meta-llama/Llama-3.2-1B - **Fine-Tuning Techniques**: Supervised Fine-Tuning (SFT) and Direct Preference Optimization (DPO) ## Benchmarks and Dataset keval leverages the custom-built **ko-bench** dataset, which draws inspiration from MT-Bench but has been tailored specifically for Korean language assessments. This dataset includes tasks spanning a wide range of user scenarios to effectively evaluate key elements like multi-turn conversation ability and instruction adherence. ## Usage Application Form To use this model, please complete the application form and submit it via email [davidkim205@gmail.com].

The `wrong` count refers to the number of incorrect answers that do not match the required format, while `length` represents the total number of test data. Other columns containing numbers indicate the count and percentage of differences between label and predicted scores for each value. The score is calculated by: 1. Calculating the difference between the label and predicted score for each pair. 2. Assigning full points for a difference of 0, and half a point for a difference of 1. 3. The total score is the sum of all points divided by the number of data points. | | model | wrong | score | length | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | |---:|:--------------|:---------|:--------|---------:|:-----------|:-----------|:-----------|:---------|:---------|:---------|:---------|:---------|----:|:---------|:---------|-----:|:---------| | 0 | kgrammar-2-9b | 0 (0.0%) | 77.5% | 80 | 52 (65.0%) | 20 (25.0%) | 5 (6.2%) | 1 (1.2%) | 1 (1.2%) | 0 | 1 (1.2%) | 0 | 0 | 0 | 0 | 0 | 0 | | 1 | kgrammar-2-3b | 0 (0.0%) | 74.4% | 80 | 51 (63.7%) | 17 (21.2%) | 8 (10.0%) | 1 (1.2%) | 1 (1.2%) | 0 | 1 (1.2%) | 1 (1.2%) | 0 | 0 | 0 | 0 | 0 | | 2 | kgrammar-2-1b | 1 (1.2%) | 67.5% | 80 | 44 (55.0%) | 20 (25.0%) | 8 (10.0%) | 2 (2.5%) | 2 (2.5%) | 1 (1.2%) | 0 | 2 (2.5%) | 0 | 0 | 0 | 0 | 0 | | 3 | gpt-4o | 1 (1.2%) | 56.9% | 80 | 34 (42.5%) | 23 (28.7%) | 14 (17.5%) | 3 (3.8%) | 2 (2.5%) | 2 (2.5%) | 0 | 0 | 0 | 0 | 0 | 0 | 1 (1.2%) | | 4 | gpt-4o-mini | 0 (0.0%) | 44.4% | 80 | 19 (23.8%) | 33 (41.2%) | 18 (22.5%) | 3 (3.8%) | 1 (1.2%) | 3 (3.8%) | 0 | 1 (1.2%) | 0 | 1 (1.2%) | 1 (1.2%) | 0 | 0 | ### Accuracy The `score` column represents the ratio of correctly predicted labels to the total number of data points. The `wrong` column shows the count and percentage of incorrectly formatted answers. The columns labeled "0" through "10" represent the number and percentage of correct predictions for each label, based on how well the model predicted each specific label. | | model | wrong | score | length | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | |---:|:--------------|:---------|:--------|---------:|:-----------|:----------|:----------|:----------|:----------|:-----------|:----------|:-----------|----:|----:|-----:|-----:|-----:| | 0 | kgrammar-2-9b | 0 (0.0%) | 65.0% | 80 | 35 (97.2%) | 5 (71.4%) | 7 (50.0%) | 3 (37.5%) | 2 (40.0%) | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | | 1 | kgrammar-2-3b | 0 (0.0%) | 63.7% | 80 | 35 (97.2%) | 2 (28.6%) | 8 (57.1%) | 3 (37.5%) | 2 (40.0%) | 1 (50.0%) | 0 | 0 | 0 | 0 | 0 | 0 | 0 | | 2 | kgrammar-2-1b | 1 (1.2%) | 55.0% | 80 | 34 (94.4%) | 3 (42.9%) | 4 (28.6%) | 2 (25.0%) | 0 | 0 | 1 (50.0%) | 0 | 0 | 0 | 0 | 0 | 0 | | 3 | gpt-4o | 1 (1.2%) | 42.5% | 80 | 9 (25.0%) | 6 (85.7%) | 8 (57.1%) | 7 (87.5%) | 1 (20.0%) | 2 (100.0%) | 0 | 1 (100.0%) | 0 | 0 | 0 | 0 | 0 | | 4 | gpt-4o-mini | 0 (0.0%) | 23.8% | 80 | 1 (2.8%) | 5 (71.4%) | 8 (57.1%) | 5 (62.5%) | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | ### Error Detection Accuracy This accuracy metric evaluates a model's error detection performance by measuring how well it identifies the presence or absence of errors. It differs from conventional accuracy by focusing on correct and incorrect error predictions rather than overall classification correctness. | | model | accuracy | wrong | length | |--:|---------------|---------:|------:|-------:| | 0 | kgrammar-2-9b | 95.0% | 0 | 80 | | 1 | kgrammar-2-3b | 93.8% | 0 | 80 | | 2 | kgrammar-2-1b | 92.5% | 1 | 80 | | 3 | gpt-4o | 65.0% | 1 | 80 | | 4 | gpt-4o-mini | 55.0% | 0 | 80 |
