`cache_prompt`: Re-use KV cache from a previous request if possible. This way the common prefix does not have to be re-processed, only the suffix that differs between the requests. Because (depending on the backend) the logits are **not** guaranteed to be bit-for-bit identical for different batch sizes (prompt processing vs. token generation) enabling this option can cause nondeterministic results. Default: `false`

|

### **GET** `/props`: Get server global properties.
|
||||
|
||||
- **GET** `/props`: Return current server settings.
|
||||
This endpoint is public (no API key check). By default, it is read-only. To make POST request to change global properties, you need to start server with `--props`
|
||||
|
||||
**Response format**
|
||||
|
||||
```json
|
||||
{
|
||||
"assistant_name": "",
|
||||
"user_name": "",
|
||||
"system_prompt": "",
|
||||
"default_generation_settings": { ... },
|
||||
"total_slots": 1,
|
||||
"chat_template": ""
|
||||
}
|
||||
```
|
||||
|
||||
- `assistant_name` - the required assistant name to generate the prompt in case you have specified a system prompt for all slots.
|
||||
- `user_name` - the required anti-prompt to generate the prompt in case you have specified a system prompt for all slots.
|
||||
- `system_prompt` - the system prompt (initial prompt of all slots). Please note that this does not take into account the chat template. It will append the prompt at the beginning of formatted prompt.
|
||||
- `default_generation_settings` - the default generation settings for the `/completion` endpoint, which has the same fields as the `generation_settings` response object from the `/completion` endpoint.
|
||||
- `total_slots` - the total number of slots for process requests (defined by `--parallel` option)
|
||||
- `chat_template` - the model's original Jinja2 prompt template
|
||||
|
||||
### POST `/props`: Change server global properties.
|
||||
|
||||
To use this endpoint with POST method, you need to start server with `--props`
|
||||
|
||||
*Options:*
|
||||
|
||||
- `system_prompt`: Change the system prompt (initial prompt of all slots). Please note that this does not take into account the chat template. It will append the prompt at the beginning of formatted prompt.
|
||||
|
||||
### POST `/v1/chat/completions`: OpenAI-compatible Chat Completions API
|
||||
|
||||
Given a ChatML-formatted json description in `messages`, it returns the predicted completion. Both synchronous and streaming mode are supported, so scripted and interactive applications work fine. While no strong claims of compatibility with OpenAI API spec is being made, in our experience it suffices to support many apps. Only models with a [supported chat template](https://github.com/ggerganov/llama.cpp/wiki/Templates-supported-by-llama_chat_apply_template) can be used optimally with this endpoint. By default, the ChatML template will be used.

### Change system prompt on runtime
|
||||
|
||||
To use the server example to serve multiple chat-type clients while keeping the same system prompt, you can utilize the option `system_prompt`. This only needs to be used once.
|
||||
|
||||
`prompt`: Specify a context that you want all connecting clients to respect.
|
||||
|
||||
`anti_prompt`: Specify the word you want to use to instruct the model to stop. This must be sent to each client through the `/props` endpoint.
|
||||
|
||||
`assistant_name`: The bot's name is necessary for each customer to generate the prompt. This must be sent to each client through the `/props` endpoint.

It is a 5 star restaurant with a great view of the city. The food is delicious and the service is excellent. The prices are reasonable and the portions are generous. The restaurant is located at 123 Main Street, New York, NY 10001. The phone number is (212) 555-1234. The hours are Monday through Friday from 11:00 am to 10:00 pm. The restaurant is closed on Saturdays and Sundays.\nUser: Who is Richard Feynman?\nAssistant: Richard Feynman was an American physicist who is best known for his work in quantum mechanics and particle physics. He was awarded the Nobel Prize in Physics in 1965 for his contributions to the development of quantum electrodynamics. He was a popular lecturer and author, and he wrote several books, including \"Surely You're Joking, Mr. Feynman!\" and \"What Do You Care What Other People Think?\".\nUser:",
