# Pythia-Chat-Base-7B-v0.16
|
||
|
||
> TLDR: As part of OpenChatKit (codebase available [here](https://github.com/togethercomputer/OpenChaT)),
|
||
> Pythia-Chat-Base-7B-v0.16 is a 7B parameter language model, fine-tuned from EleutherAI’s Pythia 7B with over 40 million instructions on 100% carbon negative compute.
|
||
|
||
Pythia-Chat-Base-7B-v0.16 is based on ElutherAI’s Pythia-7B model, and is fine-tuned with data focusing on dialog-style interactions.
|
||
We focused the tuning on several tasks such as question answering, classification, extraction, and summarization.
|
||
We’ve fine-tuned the model with a collection of 43 million high-quality instructions.
|
||
Together partnered with LAION and Ontocord.ai, who both helped curate the dataset the model is based on.
|
||
You can read more about this process and the availability of this dataset in LAION’s blog post [here](https://laion.ai/blog/oig-dataset/).
|
||
|
||
In addition to the aforementioned fine-tuning, Pythia-Chat-Base-7B-v0.16 has also undergone further fine-tuning via a small amount of feedback data.
|
||
This process allows the model to better adapt to human preferences in the conversations.
|
||
|
||
One of the notable features of Pythia-Chat-Base-7B-v0.16 is its ability to **run inference on a 12GB GPU**, thanks to the quantization technique.
|
||
It helps maintain the dialogue capabilities while making the model more accessible to a wider range of users and hardware configurations.
|
||
|
||

||
|
||
# Quick Start
|
||
|
||
## GPU Inference
|
||
|
||
This requires a GPU with 24GB memory.
|
||
```python
|
||
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||
|
||
# init
|
||
tokenizer = AutoTokenizer.from_pretrained("togethercomputer/Pythia-Chat-Base-7B-v0.16")
|
||
model = AutoModelForCausalLM.from_pretrained("togethercomputer/Pythia-Chat-Base-7B-v0.16", torch_dtype=torch.float16)
|
||
model = model.to('cuda:0')
|
||
|
||
# infer
|
||
inputs = tokenizer("<human>: Hello!\n<bot>:", return_tensors='pt').to(model.device)
|
||
outputs = model.generate(**inputs, max_new_tokens=10, do_sample=True, temperature=0.8)
|
||
output_str = tokenizer.decode(outputs[0])
|
||
print(output_str)
|
||
```
|
||
|
||
## GPU Inference in Int8
|
||
|
||
This requires a GPU with 12GB memory.
|
||
```python
|
||
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||
|
||
# init
|
||
tokenizer = AutoTokenizer.from_pretrained("togethercomputer/Pythia-Chat-Base-7B-v0.16")
|
||
model = AutoModelForCausalLM.from_pretrained("togethercomputer/Pythia-Chat-Base-7B-v0.16", device_map="auto", load_in_8bit=True)
|
||
|
||
# infer
|
||
inputs = tokenizer("<human>: Hello!\n<bot>:", return_tensors='pt').to(model.device)
|
||
outputs = model.generate(**inputs, max_new_tokens=10, do_sample=True, temperature=0.8)
|
||
output_str = tokenizer.decode(outputs[0])
|
||
print(output_str)
|
||
```
|
||
|
||
|
||
## CPU Inference
|
||
|
||
```python
|
||
from transformers import AutoTokenizer, AutoModelForCausalLM
|
||
|
||
# init
|
||
tokenizer = AutoTokenizer.from_pretrained("togethercomputer/Pythia-Chat-Base-7B-v0.16")
|
||
model = AutoModelForCausalLM.from_pretrained("togethercomputer/Pythia-Chat-Base-7B-v0.16", torch_dtype=torch.bfloat16)
|
||
|
||
# infer
|
||
inputs = tokenizer("<human>: Hello!\n<bot>:", return_tensors='pt').to(model.device)
|
||
outputs = model.generate(**inputs, max_new_tokens=10, do_sample=True, temperature=0.8)
|
||
output_str = tokenizer.decode(outputs[0])
|
||
print(output_str)
|
||
```
|
||
|
||
|
||
## Strengths of the model
|
||
|
||
There are several tasks that OpenChatKit excels at out of the box. This includes:
|
||
|
||
- Summarization and question answering within context.
|
||
- Extraction.
|
||
- Classification.
|
||
|
||
In addition, the model does well on few-shot prompts. For both classification and extraction, the model performs even better with few shots, as in most HELM tasks. [Contact us](https://www.together.xyz/contact) if you’re interested in trying few-shot prompts with the model.
|
||
|
||
## Weaknesses of the model
|
||
|
||
That said, there are several areas where we have more work to do, and we need your help! Some of these include:
|
||
|
||
- Knowledge-based closed question and answering: The chatbot may hallucinate and give incorrect results. Be sure to fact check, and if possible provide feedback with the corrected information.
|
||
- Coding tasks: The chatbot was not trained on a large enough corpus of source code to excel at writing code. We welcome contributions of additional datasets to improve this!
|
||
- Repetition: Sometimes the chatbot will repeat its response. We’re working to improve this, but in the meantime you can click the refresh button to start a new conversation.
|
||
- Context switching: If you change the topic in the middle of a conversation the chatbot often cannot make the switch automatically and will continue to give answers related to the prior topic.
|
||
- Creative writing and longer answers: The chatbot does not generate long, creative text such as an essay or story.
|
||
|
||
We are excited to work with you to address these weaknesses by getting your feedback, bolstering data sets, and improving accuracy.

|
||
|
||
Excluded uses are described below.
|
||
|
||
### Misuse, Malicious Use, and Out-of-Scope Use
|
||
|
||
The OpenChatKit community provides Pythia-Chat-Base-7B-v0.16 as an open source tool for building chatbots.
|
||
The community is not responsible for any misuse, malicious use, or out-of-scope use of the model.
|
||
It is the responsibility of the end user to ensure that the model is used in a responsible and ethical manner.
|
||
|
||
#### Out-of-Scope Use
|
||
|
||
Pythia-Chat-Base-7B-v0.16 is designed for use in chatbot applications and may not perform well for other use cases outside of its intended scope.
|
||
For example, it may not be suitable for use in safety-critical applications or for making decisions that have a significant impact on individuals or society.
|
||
It is important to consider the limitations of the model and to only use it for its intended purpose.
|
||
|
||
#### Misuse and Malicious Use
|
||
|
||
Pythia-Chat-Base-7B-v0.16 is designed for use in chatbot applications and should not be used for any other purpose.
|
||
Misuse of the model, such as using it to engage in illegal or unethical activities, is strictly prohibited and goes against the principles of the OpenChatKit community project.
|
||
|
||
Using the model to generate content that is cruel to individuals is a misuse of this model. This includes, but is not limited to:
|
||
|
||
- Generating fake news, misinformation, or propaganda
|
||
- Promoting hate speech, discrimination, or violence against individuals or groups
|
||
- Impersonating individuals or organizations without their consent
|
||
- Engaging in cyberbullying or harassment
|
||
- Defamatory content
|
||
- Spamming or scamming
|
||
- Sharing confidential or sensitive information without proper authorization
|
||
- Violating the terms of use of the model or the data used to train it
|
||
- Creating automated bots for malicious purposes such as spreading malware, phishing scams, or spamming
|
||
|
||
## Limitations
|
||
|
||
Pythia-Chat-Base-7B-v0.16, like other language model-based chatbots, has limitations that should be taken into consideration.
|
||
For example, the model may not always provide accurate or relevant answers, particularly for questions that are complex, ambiguous, or outside of its training data.
|
||
We therefore welcome contributions from individuals and organizations, and encourage collaboration towards creating a more robust and inclusive chatbot.
