The smallest cataloged machine that runs each size on the GPU (default 8K context). Bigger sizes need more memory — a rig that runs the small one may not touch the large.
| size | minimum rig | verdict | speed |
|---|---|---|---|
| 70B | NVIDIA GeForce RTX 5090 · 32GB VRAM | ✅ Runs (tight) | ~25–40 tok/s (fast) |
| 8B | AMD Radeon RX 7600 · 8GB VRAM | ✅ Runs (tight) | ~17–30 tok/s (fast) |
