# Multimodal

llama.cpp supports multimodal input via `libmtmd`. Currently, there are 2 tools support this feature:
- [llama-mtmd-cli](../tools/mtmd/README.md)
- [llama-server](../tools/server/README.md) via OpenAI-compatible `/chat/completions` API

To enable it, can use use one of the 2 methods below:

- Use `-hf` option with a [supported model](../../docs/multimodal.md)
    - To load a model using `-hf` while disabling multimodal, use `--no-mmproj`
    - To load a model using `-hf` while using a custom mmproj file, use `--mmproj local_file.gguf`
- Use `-m model.gguf` option with `--mmproj file.gguf` to specify text and multimodal projector respectively

By default, multimodal projector will be offloaded to GPU. To disable this, add `--no-mmproj-offload`

For example:

```sh
# simple usage with CLI
llama-mtmd-cli -hf ggml-org/gemma-3-4b-it-GGUF

# simple usage with server
llama-server -hf ggml-org/gemma-3-4b-it-GGUF

# using local file
llama-server -m gemma-3-4b-it-Q4_K_M.gguf --mmproj mmproj-gemma-3-4b-it-Q4_K_M.gguf

# no GPU offload
llama-server -hf ggml-org/gemma-3-4b-it-GGUF --no-mmproj-offload
```

## Pre-quantized models

These are ready-to-use models, most of them come with `Q4_K_M` quantization by default.

Replaces the `(tool_name)` with the name of binary you want to use. For example, `llama-mtmd-cli` or `llama-server`

NOTE: some models may require large context window, for example: `-c 8192`
