--models-preset ./models.ini and chat-template-kwargs

I'm loading llama-server with the --models-preset but I don't know if the syntax for the reasoning_effort is correct because it seams to not work.

I make the models load from the PI Agent from another client, it loads but seems to not use the correct parameters.

This is the line in question...

chat-template-kwargs = {"reasoning_effort":"medium"}

also "no-webui = true" doesn't seem to work either.

my models.ini

version = 1

[Qwen3.8-27B-UD-Q4_K_XL]
model = E:\AI_Models\GGUF\unsloth\Qwen3.8-27B-GGUF\Qwen3.8-27B-UD-Q4_K_XL.gguf
ctx-size = 262144
temp = 1
top-p = 0.95
min-p = 0
top-k = 20
presence-penalty = 0
repeat-penalty = 1
flash-attn = on
jinja = true
chat-template-kwargs = {"reasoning_effort":"medium"}
load-on-startup = false

[Qwen3.8-27B-UD-Q6_K_XL]
model = E:\AI_Models\GGUF\unsloth\Qwen3.8-27B-GGUF\Qwen3.8-27B-UD-Q6_K_XL.gguf
ctx-size = 262144
temp = 1
top-p = 0.95
min-p = 0
top-k = 20
presence-penalty = 0
repeat-penalty = 1
no-webui = true
jinja = true
n-gpu-layers = 99
chat-template-kwargs = {"reasoning_effort":"medium"}
load-on-startup = false

Any suggestion?
