No. Qwen3.5 122B-A10B (MoE) does not fit on RTX 4090 24GB: Q4_K_M needs 83.7 GB and 23.5 GB is usable.
Hardware: RTX 4090 24GB · Model: Qwen3.5 122B-A10B (MoE)
RTX 4090 24GB has 24 GB of VRAM and 1008 GB/s of memory bandwidth. The checker holds back 0.5 GB of VRAM for the driver and assumes 16 GB of system RAM, so fast memory usable by Ollama is 23.5 GB. Partial offload may also use 60% of that system RAM. Qwen3.5 122B-A10B (MoE) (125B, 10B active, Alibaba) at Q4_K_M is a 81 GB download and needs 83.7 GB with headroom for about 8k tokens.

Smallest hardware that runs it: M2 Max (38c GPU) 96GB at Q4_K_M (fits if the Mac GPU limit is raised, 83.7 GB needed, 72.0 GB usable, about 25 tok/s (estimate)). Can a M2 Max (38c GPU) 96GB run Qwen3.5 122B-A10B (MoE)?
A smaller Alibaba model that fits this hardware: Qwen3.5 35B-A3B (MoE) at Q4_K_M (partial offload (slower), 23.9 GB). Can a RTX 4090 24GB run Qwen3.5 35B-A3B (MoE)?
