How much memory do I need to run glm-edge-4b-chat (Q4_K_M)?

The file size is 2.63 GB (measured). With a 3,072-token context, the estimated memory including the KV cache is 4.08 GB. The formula is published at https://localllm.az-arte.com/en/guide/memory-calculation.

What is the command to run glm-edge-4b-chat with Ollama?

Run "ollama run hf.co/zai-org/glm-edge-4b-chat-gguf:Q4_K_M" to use the GGUF on Hugging Face directly. To use another quantization, replace the name at the end.

About glm-edge-4b-chat

glm-edge-4b-chat is a model published in GGUF format. GGUF files are published by zai-org/glm-edge-4b-chat-gguf. It has about 4.3B parameters, the chatglm architecture, a maximum context length of 3,072 tokens (values written in the GGUF).

There are 13 quantizations, with file sizes from 2.49 GB (Q4_0) to 8.66 GB (F16) (actual sizes on Hugging Face).

According to zai-org/glm-edge-4b-chat-gguf, the license is GLM-4 License (glm-4-9b), which allows commercial use with conditions such as scale or purpose. Check the original license for the terms of use.

File sizes are the actual values on Hugging Face. Memory is estimated for each context length (KV cache f16). The formula is in How memory is calculated.

All memory figures are Estimated (KV cache f16). It should run on a setup with at least this much VRAM (or Mac unified memory). Click a value to see the devices and models that fit that amount (Find by GPU / Mac).

About the "quality guide" (how far a quantization drifts from the original)

For each quantization type, how far the output drifts from the original model, grouped into six levels from values llama.cpp measured on Llama-3-8B.

The value is mean KLD (the difference between the original and quantized model in next-token probabilities); smaller means closer to the original. Quantizations made with an imatrix (importance data) come out slightly smaller. Levels use the value without an imatrix (or with one, for types that only have that).

These values were not measured on this model. Larger models and MoE models tend to drift less with the same type. Distributor-specific mixed types (such as UD-Q4_K_XL) cannot be matched by type name alone, so they show "-".
