Passing samplers to API - which sampler has which order number and what are the defaults?

[progmars]

I am integrating KoboldCpp into my own frontend. The initial setup works well so far. Now I want to add sampler controls to my UI but being a beginner in LLMs, I have some doubts about interpreting the documentation about samplers:
https://github.com/LostRuins/koboldcpp/wiki#what-are-samplers-how-do-i-change-or-disable-them-what-are-the-best-samplers

It says that the default (and the best) sampler order is [6,0,1,3,4,2,5]. But what are the actual samplers corresponding to those seven list indexes?

In the Swagger schemas, I see that all the sampler values are optional. But what happens if I don't send a specific value at all or send null? Would it be treated as "disabled" in KoboldCpp or would it assume some other "recommended default" value?

Thank you.

0=top_k, 1=top_a, 2=top_p, 3=tfs, 4=typ, 5=temp, 6=rep_pen

For details on each sampler, please refer to https://github.com/LostRuins/koboldcpp/wiki#what-are-samplers-how-do-i-change-or-disable-them-what-are-the-best-samplers

Generally you don't need to (and should not) change them unless you have to. If you don't send it, the optimal default settings will be used.

@LostRuins Thank you.

To have a specific example, let's say I call /generate API and do not send min_p nor temperature in the JSON request at all. Would KoboldCpp apply its own optimal defaults to those samplers or would the samplers be essentially disabled (not affecting LLMs output at all)?

[LostRuins]

Yes. The default for most advanced samplers is disabled.

Ah, I found this part in the code:

koboldcpp/koboldcpp.py

Line 980 in 65c5c77

def generate(genparams, is_quiet=False, stream_flag=False):

So, I see there that some samplers do not assume "disabled" values for missing input but instead use specific defaults. for example, 0.75 for temperature. I will have to account for this in my code; I cannot just skip the sampler in the JSON body and assume it will end up "disabled".
