The numbers behind this answer
A model comes in several sizes. Q4 is the standard one most people use; the bigger ones answer a little better but need more memory. Each row adds up the model file, the memory a conversation takes, and some working space, and compares the total with what is free on this machine.

Sources and method
Memory and speed on this page are our estimate, not a measured test. Checked . bartowski Q4_K_M GGUF.
Dense coder and reasoning model, 33.12B parameters, Apache-2.0 on the model-card metadata (the repo had no LICENSE file on 26 Oct 2026). Config: 52 layers, 8 KV heads, head dim 128, context 524,288. The parameter formula is about 19.9 GB at Q4, 35.4 GB at Q8 and 66.2 GB at FP16. Bartowski's GGUF listing on 26 Oct 2026 measured Q4_K_M at 20.79 GB, Q8_0 at 35.20 GB and the two BF16 shards at 66.24 GB together. IQ2_M on the same listing measured 12.19 GB on 27 Oct 2026 (12,187,167,872 bytes). At 8,192 tokens our estimate adds about 1.74 GB of conversation memory and 0.80 GB of working space, so the Q4_K_M total is about 23.3 GB. That fits a 24 GB GPU (an RTX 3090 or RTX 4090 leaves about 23.4 GB usable). A 32 GB Mac leaves about 21.3 GB for the GPU, so the same Q4 total is over that default share; IQ4_XS at 18.64 GB is the file that lands inside it. The IQ2_M total is about 14.7 GB, which fits a 16 GB card and misses a 12 GB card. Q8_0 at 35.20 GB fits 48 GB of VRAM or 64 GB of unified memory. FP16 at 66.24 GB fits 96 GB or 128 GB of unified memory, or two 48 GB GPUs. The Terminal-Bench 80.9 and DeepSWE 65.5 figures are the author's, and are not yet independently verified.
