Ornith: which size runs locally?

Ornith comes in 4 sizes, from 9B to 35B. Some sizes are Mixture-of-Experts, so they run faster than their memory footprint suggests. Here is each size with its Q4_K_M weight, the memory it needs, and the hardware that runs it.

Yes

Best case means the most capable device at that size (usually a discrete GPU). A Mac at the same size sits roughly one rung lower; see the per-size breakdown on each memory budget page.

FAQ

Which Ornith size should I run locally?

Pick the largest size your memory allows. On 8GB (best case) up to Ornith 1.5 9B; On 16GB (best case) up to Ornith 1.5 9B; On 24GB (best case) up to Ornith 1.5 35B-A3B; On 32GB (best case) up to Ornith 1.5 35B-A3B; On 48GB (best case) up to Ornith 1.5 35B-A3B; On 64GB (best case) up to Ornith 1.5 35B-A3B; On 128GB (best case) up to Ornith 1.5 35B-A3B; On 256GB (best case) up to Ornith 1.5 35B-A3B. Smaller sizes run faster and leave headroom for context.
