| # Model Card for `chopt-2_7b` |
| |
| <!-- Provide a quick summary of what the model is/does. --> |
| |
| AI Squared's `chopt-2_7b` is a large language model which is derived from Meta AI's Open Pre-trained Transformer language modelsand fine-tuned on a corpus of 15k records ([Databricks' "Dolly 15k" Dataset](https://huggingface.co/datasets/aisquared/databricks-dolly-15k)) to help it exhibit chat-based capabilities. Despite the permissive license of the Dolly 15k dataset, due to this model being a derivative of OPT it is restricted to use for **non-commercial research purposes**. The ChOPT family of models from AI Squared are licensed under the OPT-175B license, Copyright (c) Meta Platforms, Inc. All Rights Reserved. |
|
|
| While `chopt-2_7b` is **not a state-of-the-art model**, we believe that the level of interactivity that can be achieved on such a small model that is trained so cheaply is important to showcase, as it continues to demonstrate that creating powerful AI capabilities may be much more accessible than previously thought. |

| ## Bias, Risks, and Limitations |
|
|
| <!-- This section is meant to convey both technical and sociotechnical limitations. --> |
|
|
| **`chopt-2_7b` is not a state-of-the-art language model.** `chopt-2_7b` is an experimental technology and is not designed for use in any |
| environment other than for research purposes. Furthermore, the model can sometimes exhibit undesired behaviors. Some of these behaviors include, |
| but are not limited to: factual inaccuracies, biases, offensive responses, toxicity, and hallucinations. |
| Just as with any other LLM, we advise users of this technology to exercise good judgment when applying this technology. |
| |
| |
| ## Usage |
| |
| To use the model with the `transformers` library on a machine with GPUs, first make sure you have the `transformers` and `accelerate` libraries installed. |
| From your terminal, run: |
| |
| ```python |
| pip install "accelerate>=0.16.0,<1" "transformers[torch]>=4.28.1,<5" "torch>=1.13.1,<2" |
| ``` |
| |
| The instruction following pipeline can be loaded using the `pipeline` function as shown below. This loads a custom `InstructionTextGenerationPipeline` |
| found in the model repo [here](https://huggingface.co/aisquared/chopt-2_7b/blob/main/instruct_pipeline.py), which is why `trust_remote_code=True` is required. |
| Including `torch_dtype=torch.bfloat16` is generally recommended if this type is supported in order to reduce memory usage. It does not appear to impact output quality. |
| It is also fine to remove it if there is sufficient memory. |
| |
| ```python |
| from transformers import pipeline |
| import torch |
| |
| generate_text = pipeline(model="aisquared/chopt-2_7b", torch_dtype=torch.bfloat16, trust_remote_code=True, device_map="auto") |
| ``` |
| |
| You can then use the pipeline to answer instructions: |
| |
| ```python |
| res = generate_text("Who was George Washington?") |
| print(res) |
| ``` |
| |
| Alternatively, if you prefer to not use `trust_remote_code=True` you can download [instruct_pipeline.py](https://huggingface.co/aisquared/chopt-2_7b/blob/main/instruct_pipeline.py), |
| store it alongside your notebook, and construct the pipeline yourself from the loaded model and tokenizer: |
| |
| ```python |
| from instruct_pipeline import InstructionTextGenerationPipeline |
| from transformers import AutoModelForCausalLM, AutoTokenizer |
| import torch |
| |
| tokenizer = AutoTokenizer.from_pretrained("aisquared/chopt-2_7b", padding_side="left") |
| model = AutoModelForCausalLM.from_pretrained("aisquared/chopt-2_7b", device_map="auto", torch_dtype=torch.bfloat16) |
| |
| generate_text = InstructionTextGenerationPipeline(model=model, tokenizer=tokenizer) |
| ``` |
| |
| |
| ### Model Performance Metrics |
| |
| We present the results from various model benchmarks on the EleutherAI LLM Evaluation Harness for all models in the ChOPT family. |
| Model results are sorted by mean score, ascending, to provide an ordering. These metrics serve to further show that none of the DLite models are |
| state of the art, but rather further show that chat-like behaviors in LLMs can be trained almost independent of model size. |
