Finetuning Query for gpt-oss

Thank you so much BEN for your quick support and time, I will surely try all the things that you mentioned. 1 last question you mentioned to use thinking, I am using harmony format and it has the <|end|> as thinking eos for analysis channel and then final message will start so should i change this entirely as per your suggestion will it lead to catastrophic forgetting How we should also take care of 1. Catastrophic forgetting 2. Routing collapse in MoE 3. NaN/diverging loss 4. Overfittig Thank you once again..
