# ✨ Yi 200k context SFT models |
|
These are chat fine-tuned versions of the Yi 200k context length models: |
|
- Supervised Fine-tuning allows the model to respond in a cleaner chat format that ends with EOS tokens. |
|
- Note that this is a fine-tune of the llamafied model, meaning that all llama platforms can be used for inference. |
|
|
|
Available models: |
|
- Purchase access to the 6B model [here](https://buy.stripe.com/9AQ00M5tP3LBg7e00J) |
|
- Purchase access to the 34B model [here](https://buy.stripe.com/28o00Mf4p81RaMUdRA) |
|
|
|
GGUF models are in the base model repos (along with the bf16 weight safetensors). AWQ models are in the '-AWQ' repos (34B AWQ will be released by EOD 20 Nov 2023). When you purchase access, you get access to all model variants for that model size. |
|
|
|
Notably: |
|
- The data used for fine-tuning is Apache 2 licensed and not generated using AI, thereby allowing this chat model to be used commercially, which is particularly useful for data preparation and generation for training other models. |
|
- The purchase of access to this model grants the user permission to use the model commercially for inference or fine-tuning and inference. |

|
While benchmarking open-source models, we have observed a disparity between the |
|
results generated by our pipeline and those reported in public sources (e.g. |
|
OpenCompass). Upon conducting a more in-depth investigation of this difference, |
|
we have discovered that various models may employ different prompts, |
|
post-processing strategies, and sampling techniques, potentially resulting in |
|
significant variations in the outcomes. Our prompt and post-processing strategy |
|
remains consistent with the original benchmark, and greedy decoding is employed |
|
during evaluation without any post-processing for the generated content. For |
|
scores that were not reported by the original authors (including scores reported |
|
with different settings), we try to get results with our pipeline. |
|
|
|
To evaluate the model's capability extensively, we adopted the methodology |
|
outlined in Llama2. Specifically, we included PIQA, SIQA, HellaSwag, WinoGrande, |
|
ARC, OBQA, and CSQA to assess common sense reasoning. SquAD, QuAC, and BoolQ |
|
were incorporated to evaluate reading comprehension. CSQA was exclusively tested |
|
using a 7-shot setup, while all other tests were conducted with a 0-shot |
|
configuration. Additionally, we introduced GSM8K (8-shot@1), MATH (4-shot@1), |
|
HumanEval (0-shot@1), and MBPP (3-shot@1) under the category "Math & Code". Due |
|
to technical constraints, we did not test Falcon-180 on QuAC and OBQA; the score |
|
is derived by averaging the scores on the remaining tasks. Since the scores for |
|
these two tasks are generally lower than the average, we believe that |
|
Falcon-180B's performance was not underestimated. |

## Usage |
|
|
|
Please visit our [github repository](https://github.com/01-ai/Yi) for general |
|
guidance on how to use this model. |
|
|
|
## Disclaimer |
|
|
|
Although we use data compliance checking algorithms during the training process |
|
to ensure the compliance of the trained model to the best of our ability, due to |
|
the complexity of the data and the diversity of language model usage scenarios, |
|
we cannot guarantee that the model will generate correct and reasonable output |
|
in all scenarios. Please be aware that there is still a risk of the model |
|
producing problematic outputs. We will not be responsible for any risks and |
|
issues resulting from misuse, misguidance, illegal usage, and related |
|
misinformation, as well as any associated data security concerns. |
