Ornith 1.0 397B
396.8 billion parameters in total, but only 14.62 billion are read for each token. That split is the whole point of the design: it costs the memory of a large model and the speed of a small one. Grouped-query attention keeps the cache small, so long contexts cost less here than on models of the same size.
Memory needed, by quantisation
At an 8k context window. Quality is our rough ranking of how much the compression costs you: anything at or above Q5 is hard to tell apart from the original in normal use.
| Quantisation | File size | KV cache | Total VRAM | Quality | What it costs you |
|---|---|---|---|---|---|
| Q8_0 | 392.65 GB | 0.94 GB | 394.43 GB | 99% | Lossless in practice. Use it when the memory is there. |
| Q6_K | 303.03 GB | 0.94 GB | 304.82 GB | 98% | Very close to Q8 for two thirds of the size. |
| Q5_K_M | 262.84 GB | 0.94 GB | 264.63 GB | 96% | The quality-first choice when Q6 will not fit. |
| Q4_K_M | 223.12 GB | 0.94 GB | 224.9 GB | 93% | The default. Best size-to-quality ratio for local use. |
| IQ4_XS | 196.32 GB | 0.94 GB | 198.11 GB | 91% | Importance-matrix 4-bit. Q4_K_S quality, smaller file. |
| Q3_K_M | 180.62 GB | 0.94 GB | 182.41 GB | 86% | Degradation starts to show. A way to fit one size up. |
| IQ3_XXS | 141.35 GB | 0.94 GB | 143.14 GB | 79% | Aggressive. Only worth it on very large models. |
What a longer conversation costs
Same model at Q4_K_M, only the context window changes. The cache grows in a straight line with every token in the window.
| Context | KV cache | Total VRAM | Fits in 8 GB | Fits in 12 GB | Fits in 24 GB |
|---|---|---|---|---|---|
| 4k | 0.47 GB | 224.31 GB | no | no | no |
| 8k | 0.94 GB | 224.9 GB | no | no | no |
| 16k | 1.88 GB | 226.09 GB | no | no | no |
| 32k | 3.75 GB | 228.47 GB | no | no | no |
| 64k | 7.5 GB | 233.22 GB | no | no | no |
| 128k | 15 GB | 242.72 GB | no | no | no |
The "fits" columns allow for the roughly 0.8 GB Windows keeps for the desktop.

What to buy to run Ornith 1.0 397B
The cheapest hardware that runs it at a quantisation worth using and a speed you would not resent, at an 8k context window.
Cheapest that works
Apple M3 Ultra 512GB
$9,499 whole machine
Q6_K · uses 304.52 GB of its 512 GB · about 52.8 tokens/s
If it just has to run
Apple M3 Ultra 256GB
$5,599 whole machine
Q3_K_M · about 84.1 tokens/s. Cheaper because it runs the model at a lower precision.
