Simple API server for llama.cpp implementation of LLaVA.
Download one of ggml-model-*.gguf and mmproj-model-f16.gguf from here. Then, simply invoke:
bin/llava-server -m ggml-model-q5_k.gguf --mmproj mmproj-model-f16.gguf
This will start a server on localhost:8080. You can change the hostname and port with --host and --port, respectively, and enable HTTP logging with --log-http. You should be able to interact with the server at localhost:8080 in a web browser.
The LLaVA endpoint is at /llava. The request body takes the following parameters:
| Name | Type | Required | Description |
|---|---|---|---|
| user_prompt | string | yes | The prompt (e.g., "what is this?") |
| image_file | file | yes | Image data in binary form. |
| system_prompt | string | no | System prompt. |
The llama.cpp and cpp-httplib repositories are included as gitmodules. After cloning, make sure to first run:
git submodule init
git submodule update
Then to build, simply run:
make
So far, this has only been tested on macOS, but should work anywhere else llama.cpp builds.
