About GLM-5.3-Flash-CYBERSECURITY

GLM-5.3-Flash-CYBERSECURITY is a GGUF model based on dealignai/GLM-5.3-Flash-CYBERSECURITY-W4A16 on Hugging Face. GGUF files are published by SyndicateLabs/GLM-5.3-Flash-CYBERSECURITY-GGUF. It has about 313.3B parameters, the glm5-next architecture, a maximum context length of 1,048,576 tokens (values written in the GGUF).

There are 5 quantizations, with file sizes from 101 GB (IQ1_M) to 196 GB (Q4_K_M) (actual sizes on Hugging Face).

Running Q4_K_M (196 GB) with an 8,192-token context needs an estimated 197 GB of memory, and an estimated 197 GB at 32,768 tokens. For 8,192 tokens, a GPU with 192 GB or more of VRAM, or a Mac with 192 GB or more of unified memory, is a rough guide (macOS caps how much memory the GPU can use, so leave some headroom). The smallest, IQ1_M (101 GB), needs an estimated 102 GB at 8,192 tokens.

File size and estimated memory per quantization

  • Up to 8 GB
  • Up to 16 GB
  • Up to 24 GB
  • Up to 48 GB
  • Up to 128 GB
  • More

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 "-".

How to run

Mainline llama.cpp can load this model's format (glm5-next) from b11279 (Sep 30, 2026) onward. Ollama and LM Studio bundle llama.cpp internally, so an older app fails to load it with errors such as "unknown model architecture". If that happens, update the app.

Example commands using Q4_K_M. To use another quantization, replace the name with one from the table above. How to run local LLMs

Ollama

Run it by pointing directly at the GGUF on Hugging Face.

ollama run hf.co/SyndicateLabs/GLM-5.3-Flash-CYBERSECURITY-GGUF:Q4_K_M

llama.cpp

Pass the repository and quantization name to llama-server (or llama-cli) with -hf.

llama-server -hf SyndicateLabs/GLM-5.3-Flash-CYBERSECURITY-GGUF:Q4_K_M

LM Studio

Paste SyndicateLabs/GLM-5.3-Flash-CYBERSECURITY-GGUF into the search box, download it, and choose the quantization from the file list.
