# llama.cpp INI Presets
## Introduction
The INI preset feature, introduced in [PR#17859](https://github.com/ggml-org/llama.cpp/pull/17859), allows users to create reusable and shareable parameter configurations for llama.cpp.
### Using Presets with the Server
When running multiple models on the server (router mode), INI preset files can be used to configure model-specific parameters. Please refer to the [server documentation](../tools/server/README.md) for more details.
### Using a Remote Preset
> [!NOTE]
>
> This feature is currently only supported via the `-hf` option.
For GGUF models hosted on Hugging Face, you can include a `preset.ini` file in the root directory of the repository to define specific configurations for that model.
Example:
```ini
hf-repo-draft = username/my-draft-model-GGUF
temp = 0.5
top-k = 20
top-p = 0.95
```
For security reasons, only certain options are allowed. Please refer to [preset.cpp](../common/preset.cpp) for the complete list of permitted options.
Example usage:
Assuming your repository `username/my-model-with-preset` contains a `preset.ini` with the configuration above:
```sh
llama-cli -hf username/my-model-with-preset
# This is equivalent to:
llama-cli -hf username/my-model-with-preset \
--hf-repo-draft username/my-draft-model-GGUF \
--temp 0.5 \
--top-k 20 \
--top-p 0.95
```
You can also override preset arguments by specifying them on the command line:
```sh
# Force temp = 0.1, overriding the preset value
llama-cli -hf username/my-model-with-preset --temp 0.1
```
If you want to define multiple preset configurations for one or more GGUF models, you can create a blank HF repo for each preset. Each HF repo should contain a `preset.ini` file that references the actual model(s):
```ini
hf-repo = user/my-model-main
hf-repo-draft = user/my-model-draft
temp = 0.8
ctx-size = 1024
; (and other configurations)
```
### Named presets
If you want to define multiple preset configurations for one or more GGUF models, you can create a blank HF repo containing a single `preset.ini` file that references the actual model(s):
```ini
[*]
mmap = 1
[gpt-oss-20b-hf]
hf = ggml-org/gpt-oss-20b-GGUF
batch-size = 2048
ubatch-size = 2048
top-p = 1.0
top-k = 0
min-p = 0.01
temp = 1.0
chat-template-kwargs = {"reasoning_effort": "high"}
[gpt-oss-120b-hf]
hf = ggml-org/gpt-oss-120b-GGUF
batch-size = 2048
ubatch-size = 2048
top-p = 1.0
top-k = 0
min-p = 0.01
temp = 1.0
chat-template-kwargs = {"reasoning_effort": "high"}
```
You can then use it via `llama-cli` or `llama-server`, example:
```sh
llama-server -hf user/repo:gpt-oss-120b-hf
```
Please make sure to provide the correct `hf-repo` for each child preset. Otherwise, you may get error: `The specified tag is not a valid quantization scheme.`
