Yes. GLM-OCR 0.9B fits in fast memory on RTX 3090 24GB at BF16 (3.7 GB needed, 23.5 GB usable), about 208 tok/s (estimate).
Hardware: RTX 3090 24GB · Model: GLM-OCR 0.9B
RTX 3090 24GB has 24 GB of VRAM and 936 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. GLM-OCR 0.9B (1.33B, Z.ai) at BF16 is a 2.7 GB download and needs 3.7 GB with headroom for about 8k tokens.
