**TLDR:** Multiple dataset varsa nasıl karıştırırsın? Naïve concatenation = büyük dataset dominates. Sampling temperature, proportional mixing, DoReMi (Xie et al. 2023) algoritması ile dynamic reweighting. Türkçe SFT mix örneği: %40 TR-Alpaca + %25 OASST + %20 ShareGPT-TR + %15 custom — niye bu yüzde?
