Model library → Poolside Laguna XS 2.1 → Laguna XS 2.1 33B-A3B
33B total parameters with only 3B activated per token, which is what lets a model scoring 70.9% on SWE-Bench Verified sit on a single 24GB card. Mixed sliding-window + global attention (3:1 across 40 layers), sigmoid per-head gating, FP8 KV cache, 256K context. Released under OpenMDW-1.1 — the Linux Foundation / NVIDIA permissive model-weights framework — not Apache 2.0, so check the terms if you are redistributing.
Laguna XS 2.1 33B-A3B needs about 21 GB of VRAM at Q4_K_M — quantized weights plus framework overhead, before any KV cache. On Apple Silicon that figure comes out of unified memory.

OpenMDW-1.1 — commercial use permitted. Commercial use permitted. No usage restrictions beyond attribution.
Modelled on a reference NVIDIA RTX 4090 (24 GB), with no KV cache (this record has no published architecture). Speed figures are ESTIMATES from the memory-bandwidth roofline described on the methodology page, not benchmarks we ran — rows marked measured come from published or reader-submitted runs. VRAM here includes the KV cache, so it reads higher than the headline figure above, which does not.
| Quant | Weights | VRAM needed | Est. speed | Fit on 24 GB |
|---|---|---|---|---|
| Q2_K | 10.8 GB | 11.6 GB | ~210 tok/s (est.) | Fits comfortably |
| Q3_K_M | 14.1 GB | 14.9 GB | ~194 tok/s (est.) | Fits comfortably |
| Q4_K_M | 19.9 GB | 20.7 GB | ~171 tok/s (est.) | Fits comfortably |
| Q5_K_M | 23.4 GB | 24.2 GB | ~24 tok/s (est.) | Offloads to system RAM (slow) |
| Q6_K | 27.1 GB | 27.9 GB | ~22 tok/s (est.) | Offloads to system RAM (slow) |
| Q8_0 | 35.1 GB | 35.9 GB | ~20 tok/s (est.) | Offloads to system RAM (slow) |
| F16 | 66.0 GB | 66.8 GB | — | Won't fit |
