Input Format

The model is trained to use the following format (note the newlines):

<|user|>
Your message here!
<|assistant|>

For best results, format all inputs in this manner. Make sure to include a newline after <|assistant|>, this can affect generation quality quite a bit. We have included a chat template in the tokenizer implementing this template.

Bias, Risks, and Limitations

These models have not been aligned to generate safe completions, so the model can produce problematic outputs (especially when prompted to do so).

Training hyperparameters

The following hyperparameters were used during training:

learning_rate: 2e-05
total_train_batch_size: 128
optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08
lr_scheduler_type: linear
lr_scheduler_warmup_ratio: 0.03
num_epochs: 2.0
