NOTE: There is some issue with LLaMa-2 7B and fine-tuning only works if you use fp16=False and bf16=True in the HF trainer. Gathering more intel on this but if you have any thoughts about this issue or performance, please let us know!

Platypus-7B is an instruction fine-tuned model based on the LLaMA2-7B transformer architecture.

Limitations and bias

Llama 2 and fine-tuned variants are a new technology that carries risks with use. Testing conducted to date has been in English, and has not covered, nor could it cover all scenarios. For these reasons, as with all LLMs, Llama 2 and any fine-tuned varient's potential outputs cannot be predicted in advance, and the model may in some instances produce inaccurate, biased or other objectionable responses to user prompts. Therefore, before deploying any applications of Llama 2 variants, developers should perform safety testing and tuning tailored to their specific applications of the model.
