At Q4_K_M with a 32K context, Qwen3.5 122B-A10B needs about 80.6 GB of GPU or unified memory by our estimate. The official checkpoint is 250 GB on disk.
Hybrid model: only the full-attention layers keep a growing KV cache; linear/conv layers keep a small fixed state (not counted).

Speed ceiling is memory bandwidth divided by the bytes of (active) weights read per token, shown only where we have a sourced bandwidth figure. Real decode speed is lower, especially with long contexts or when splitting across cards. All memory numbers are estimates; see the methodology.
FAQ
- How much VRAM does Qwen3.5 122B-A10B need?
- About 80.6 GB at Q4_K_M with a 32K-token context (76.5 GB weights, 0.8 GB KV cache, 3.3 GB overhead). These are estimates.
- Can I run Qwen3.5 122B-A10B on a single GPU?
- Not at Q4_K_M with 32K context on any single GPU in our catalog. Use several GPUs, a high-memory unified-memory machine, a smaller quantization or a shorter context.
- Which apps can run Qwen3.5 122B-A10B locally?
- Verified so far: Ollama, LM Studio, llama.cpp, MLX (mlx-lm), KTransformers, vLLM, SGLang. Each entry links to its source on this page.
