i dont understand the nuances here. what does this mean. 4.8 is trained on same model as previous one then? what does brand new mean.

It means for 4.7 they trained a new base model with different architecture, different pre-training data (later knowledge cutoff), and a new tokenizer. Vs finetuning an existing model, which was the case for 4.6, and probably for 4.8.

[dominotw]

do you mean pre training? so 4.8 is just post training of an old pretrained model?

btw where do they tell you how they trained the model.
