About test-model-router-download

test-model-router-download is a model published in GGUF format. GGUF files are published by ggml-org/test-model-router-download. It has about 1M parameters, the llama architecture, a maximum context length of 2,048 tokens (values written in the GGUF).

There is one quantization, F16, with a file size of 0.00 GB (actual size on Hugging Face).

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

Example commands using F16. 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/ggml-org/test-model-router-download:F16

llama.cpp

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

llama-server -hf ggml-org/test-model-router-download:F16

LM Studio

Paste ggml-org/test-model-router-download into the search box, download it, and choose the quantization from the file list.

Frequently asked questions

How much memory do I need to run test-model-router-download (F16)?
The file size is 0.00 GB (measured). With a 2,048-token context, the estimated memory including the KV cache is 1.08 GB. The formula is published at https://localllm.az-arte.com/en/guide/memory-calculation.
What is the command to run test-model-router-download with Ollama?
Run "ollama run hf.co/ggml-org/test-model-router-download:F16" to use the GGUF on Hugging Face directly. To use another quantization, replace the name at the end.
