how much the prompt of a request must match the prompt of a slot in order to use that slot (default: 0.50, 0.0 = disabled)
--lora-init-without-apply
load LoRA adapters without applying them (apply later via POST /lora-adapters) (default: disabled)
logging:
--simple-io use basic IO for better compatibility in subprocesses and limited consoles
-ld, --logdir LOGDIR path under which to save YAML logs (no logging if unset)
--log-test Run simple logging test
--log-disable Disable trace logs
--log-enable Enable trace logs
--log-file FNAME Specify a log filename (without extension)
--log-new Create a separate new log file on start. Each log file will have unique name: "<name>.<ID>.log"
--log-append Don't truncate the old log file.
```
Available environment variables (if specified, these variables will override parameters specified in arguments):
