What does each model name stand for? #3508

There are numbers of models in https://github.com/LAION-AI/Open-Assistant/blob/main/oasst-shared/oasst_shared/model_configs.py.

e.g., _lorem, OA_SFT_Llama_13B.

Where can we find what it stands for? And which model is better?

Based on my testing, distilgpt2 gives meaningless response, and _lorem always hangs to give no response.

Thanks!
