According to definition 1.21 and remark 1.23 in

  • Clark Barwick , On left and right model categories and left and right Bousfield localization (pdf)

a model category is called tractable if it is combinatorial and it has sets I and J of generating cofibrations and acyclic cofibrations, respectively, whose sources are all cofibrant?.
