Convert-to-Quant (`ctq`) is installed for normal quantizations.
`hf`, the Hugging Face CLI command, and llama.cpp's compiled binaries are also available.

For GGUF quantizations, try:
- `hf_to_nvfp4_quant` (huggingface structure to GGUF)
- `gguf_to_nvfp4_quant` (GGUF to GGUF)
- `safetensors_to_nvfp4_quant` (ComfyUI style safetensors to GGUF (untested))
- `hf_to_nvfp4_safetensors` (huggingface structure to ComfyUI style safetensors)

For model info, try:
- `hf_info` (huggingface structure)
- `gguf_info` (GGUF structure)
---

Example:

```bash
hf download coder3101/gemma-4-12B-it-heretic --local-dir gemma-4-12B-it-heretic
hf_to_nvfp4_gguf -o gemma-4-12B-it-heretic_nvfp4 gemma-4-12B-it-heretic
```

This would create a NVFP4 GGUF for Ollama/llama.cpp from `https://huggingface.co/coder3101/gemma-4-12B-it-heretic`

The same directory can be quantized to one ComfyUI NVFP4 safetensors file:

`hf_to_nvfp4_safetensors -o gemma-4-12B-it-heretic-NVFP4.safetensors gemma-4-12B-it-heretic`

Conversions between formats without quantization is available in the custom commands with `--no-quant`.
