Some of the most exciting engineering work is happening in the DS4 repo - and I'm watching it almost like a sports game. When the DSpark paper came out[1] the next day we had folks attempting to implement, working together, validating their failures. Eventually their work being synthesized into a PR[1] that admits performance is not ideal. Something antirez alluded to in one of his videos (speculative decoding is a great boon, but mostly for large labs hosting and serving many requests at once, and maybe not so effective for local inference). There's recent work into "directional steering"[3] that has made it's way into per-session directional steering overrides thanks to audreyt[4]. There's support for the new Hy3[5] model also thanks to audreyt[6]. There's Pre-M5 optimizations[7] in the queue thanks to ivanfioravanti who also helped wit

h some of the initial M5 optimizations. I haven't watched a repo like this since llama.cpp and whisper.cpp in the early days (though llama.cpp is pretty exciting right now with the SYCL improvements that are flowing in for the new Intel GPUs). The DS4 repo is a really interesting place to watch folks who heavily code with agents collaborate together in a way that seems pretty effective. I've been really enjoying it.
