DeepSeek V4.1 Flash 1017 Support for ds4 · PR #1225 · antirez/ds4

Just pushed a PR for dwarfstar that adds support for Deepseek-v4.1-Flash-1017 with its new engrams and updated vision tower.

Proof1 community thread

Key points

  • The PR basically just adds compatibility for the file revisions and checks to make sure the vision+language model file combination matches, raising on mixed pairings.
  • Any files quantized with the ds4 quantization suite will load without any special changes, and it introduces no regressions for the previous checkpoint.
  • This is a major revision, with ~40% of the routed expert tensors changed, 30% in the engrams, and ~50% of the vision tower's expert tensors changed.
  • Shortly, I will be uploading my Q2-Q8 mixed quant for 128GB w/ minor SSD offloading (152GB wired, 366GB total with engrams, following antirez's recipe for the previous checkpoint), and will make a thread when it's ready.
