How much memory does Ornith 1.5 122B need?
Ornith 1.5 122B is a 125.09B mixture-of-experts model (10B active per token) built for agentic coding. The weights alone take 75.8 GB at Q4_K_M; add context and the OS, and it belongs in the 96 GB memory class. Every number below comes from the ModelFit engine: speeds are estimates, labeled est., because we do not benchmark hardware ourselves.
KV = fp16 estimate (q8_0 cache roughly halves it). "Comfortable" = weights + KV within the engine's tiered budget (~70-85% of memory).
