Can I run granite-4.1-30b?

granite-4.1-30b needs about 21.1 GB of memory at Q4_K_M, and the cheapest GPU we track that holds it is the Intel Arc Pro B70 32GB (32 GB, $949 list price). 25 of the 82 devices we track run it fully at Q4. These are estimates, not measured benchmarks.

Memory by context length

Longer chats and documents need more memory for the KV cache. All 64 layers keep a full cache. Sizes assume an FP16 KV cache; a Q8 cache roughly halves the cache part.

From the model's config.json (64 full-attention layers × 8 KV heads × 128 head size, retrieved 2026-11-04). Check the model card for its maximum supported context. Try other sizes in the VRAM calculator or compare models in our context length guide.
