Act as an expert and answer the following knowledge - based question: Can I charge an Android phone with a Lightning cable? |
No. Lightning cables are only suitable for iPhones and iPads. Android phones need USB - C cables to charge. |
Act as an expert and answer the following knowledge - based question: Why is the sky blue? |
There are mainly two reasons why the sky is blue. First, there are particles and moisture in the atmosphere. These particles scatter light, causing longer - wavelength colors such as red, yellow, and purple to be scattered, leaving only blue light. Second, the Earth's atmosphere is not completely transparent and has a refraction effect. So the blue light we see also includes the blue light reflected from the direction of the sun. |
Act as an expert and answer the following knowledge - based question: How to make pizza? |
To make pizza, you need to prepare biscuits, sauce, and cheese first. Preheat a frying pan or baking tray, add an appropriate amount of soy sauce, and mix it with an appropriate amount of flour to make biscuits. Then wipe the moisture off the surface of the biscuits and knead them into round biscuits by hand. Spread an appropriate amount of soy sauce on the biscuits, and then sprinkle an appropriate amount of cheese and other ingredients. Finally, put it in the oven and bake for 10 - 15 minutes until the crust becomes crispy and the cheese inside is completely melted. |
Act as an expert and answer the following knowledge - based question: Why was Pluto kicked out of the solar system? |
Pluto was formed by the matter in the solar system along its flight path. In the early days of the solar system, they would gather together due to gravity and form a large and stable core. Then, Pluto would move inward from the periphery until it collided and merged with other small bodies to form a larger and stable core. Eventually, Pluto could no longer maintain a balanced state, so it was kicked out of the solar system. |
Act as an expert and answer the following knowledge - based question: What are the main planets in the solar system? |
There are 8 main planets in the solar system, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. |

Model Training
Backbone Model Selection
The Anima model was trained for 10,000 steps based on the open - source 33B guanaco using QLoRA. The training used a single H100 GPU.
- Thought Process: This work is mainly to verify the effectiveness of the QLoRA training method. Therefore, we chose to fine - tune the Guanaco 33B model based on QLoRA, which mainly enhances the Chinese language capabilities of the model. It is assumed that the model's basic logical reasoning and knowledge capabilities are already sufficient.
Training Data Selection
We used the training dataset guanaco_belle_merge_v1.0 open - sourced by the Chinese - Vicuna project for fine - tuning.
- Thought Process: According to the conclusions of the Grid Search in QLoRA Appendix B.4 and Table 9, for QLoRA fine - tuning, a larger training sample size is not necessarily better. 10,000 steps is a size with a relatively good ROI. Therefore, we hope to select a dataset with no less than 10,000 steps. The Belle 10M dataset seems too large, and the data quality is uncertain. Due to limited time, we first selected guanaco_belle_merge_v1.0. In the future, we will conduct more systematic tests on more datasets and data quality screening.
- Thanks: We would like to thank the contributions of the Chinese - Vicuna project, the Belle project, and the GuanacoDataset.
Hyperparameter Selection
Based on the consideration of cost - ROI balance, we did not conduct extensive grid searches. The basic idea is to follow the conclusions of the QLoRA paper because QLoRA has conducted relatively detailed hyperparameter grid search experiments:
- Batch size: 16 (QLoRA Appendix B.4 and Table 9)
- Max steps: 10,000 (QLoRA Appendix B.4 and Table 9). Further experiments on training with more steps and larger datasets are in progress, and updates will be provided continuously.
- Learning rate: 1e - 4 (QLoRA Appendix B.4 and Table 9)
- LoRA r = 64, alpha = 16 (QLoRA Appendix B.2)
- source_max_len = 512, target_max_len = 512: We need to ensure that most training samples are not truncated so that the information can be fully trained into the model. According to the estimation in the script, 512 can cover the length of most samples.

Elo Rating Tournament Results
Model | Elo | Rank |
---|---|---|
ChatGPT - 3.5 turbo | 1341.98 | 1 |

Evaluation Methodology
- Dataset Selection: As discussed in the Belle Paper, the different type distributions of the evaluation set have a huge impact on the evaluation results. Similar to the story of Tian Ji's horse - racing, it is easy to gain an advantage by using one's strengths against others' weaknesses. Therefore, we selected the [Vicuna benchmark](https://lmsys.org/blog/2023 - 03 - 30 - vicuna/), which is widely recognized in the research of English chatbot models. To evaluate the Chinese language, we used GPT4 to translate the questions. Translation code and Dataset.
- Evaluation Method: To balance the cost, we mainly used GPT4 for evaluation. As demonstrated in QLoRA, simply using GPT4 scores for model comparison has relatively large random fluctuations, which is consistent with our observations. Therefore, we adopted the Elo Rating tournament evaluation method recommended by QLoRA, which is currently widely used.
- Hyperparameter Selection: Considering the cost, we chose 300 rounds of random evaluation, randomly selected the order of model PK to offset the influence of the order, and the random seed was 42. The implementation code of Elo rating and other hyperparameters refer to [Vicuna's Elo code](https://raw.githubusercontent.com/lm - sys/FastChat/833d65032a715240a3978f4a8f08e7a496c83cb1/fastchat/serve/monitor/elo_analysis.py): K = 32, init rating = 1000.

Conclusion
The most important capabilities of an LLM are logical reasoning and knowledge encoding. Therefore, the scale of the model is still the most important factor. Through the QLoRA method, we can fine - tune the largest possible model under given hardware conditions at a low cost to achieve the optimal effect.
The Anima model has achieved the best results among Chinese models after only 10,000 steps of training without in - depth optimization of the training data quality.
