Close, but only with CPU offload
These need more than the card holds at their smallest practical quant, so part of the model runs from system memory (figures assume 32 GB of it). They work, several times slower.

|---|---|---|---|
| Llama 3.1 8B | 8B | 6.4 GB needed | 8.4 GB |

How to read this
The NVIDIA GTX TITAN Z features 6 GB of GDDR5 memory. This memory size is the absolute limit for loading local artificial intelligence models directly onto the graphics card. To run a model entirely on the hardware, the model files and the active memory space must fit within this 6 GB boundary. Keeping the entire model on the card ensures the fastest possible processing speeds.
The quantization column shows the compression level used to shrink these files. Quantization reduces the precision of model weights to save space. For example, Granite 3.3 8B, Ministral 8B, InternLM 3 8B, OpenCoder 8B, Seed-Coder 8B, MiniCPM-V 2.6, Idefics 3 8B, Fuyu-8B, Emu3, and Stable Diffusion 3.5 Large fit within 5.9 GB of memory using the Q4_K_M quantization. EXAONE 3.5 7.8B and Mistral 7B also fit within 5.7 GB of memory at this same Q4_K_M level.
Other models use the slightly higher precision Q5_K_M quantization. Qwen2.5 7B, OLMo 2 7B, Falcon 3 7B, Command R7B, OpenHermes 2.5, Zephyr 7B Beta, OpenChat 3.5, Starling LM 7B, Codestral Mamba 7B, CodeGemma 7B, aiXcoder-7B, Nxcode, Janus-Pro 7B, Ruyi-Mini-7B, Qwen2-Audio 7B, Qwen2.5-Omni 7B, and YuE use exactly 6 GB of memory at Q5_K_M. Magicoder-S-DS 6.7B fits within 5.7 GB of memory at Q5_K_M.
When a model exceeds the 6 GB limit, you must offload some layers to your system RAM. This offloading process allows you to run larger models but slows down the generation speed. For these cases, we assume your computer has 32 GB of system RAM. Llama 3.1 8B requires 6.4 GB of memory at Q4_K_M and needs 8.4 GB of system RAM. Chroma requires 6.5 GB of memory at Q4_K_M and needs 8.5 GB of system RAM. Gemma 2 9B requires 8 GB of memory at Q4_K_M and needs 10 GB of system RAM.
Other offload options include Nemotron Nano 9B, GLM-4 9B, Yi-Coder 9B, GLM-4-9B-Chat, and GLM-4V-9B. These models require 6.6 GB of memory at Q4_K_M and need 8.6 GB of system RAM. Mochi 1 requires 7.3 GB of memory at Q4_K_M and needs 9.3 GB of system RAM. Open-Sora 2.0 requires 8.1 GB of memory at Q4_K_M and needs 10.1 GB of system RAM.
All memory calculations are based on a standard 4k context window. If you increase the context window to process longer texts, the memory requirements will rise. This extra memory usage might force you to use lower quantization levels or offload more layers to system RAM.
