The author says the upstream GGUF format changed, so the implementation is being updated to support the newer variant as well.
He also says the DwarfStar laguna-s2.1 branch now includes a GPT5.6-Sol-coded implementation of Laguna S2.1, manually sanity-tested on non-trivial tasks. On an M5 Max, it reportedly reaches about 50 tokens/s generation and 500 tokens/s prefill, with Metal support for now and other backends to be written later.
