DeepSeek-V4.1-Flash EXL3 is finally alive across 4× DGX Sparks. 🔥 I built the quality-first 4.75 bpw SAGE quant. @cfontes and @Blackwellboy spent more than a week, 14 PRs, dozens of commits and 40+ bring-up iterations making it actually run. I don’t own one Spark, let alone four. This is what open-source collaboration looks like.
