Add Deepseek-v3 (api version) to high and medium inteligence models list.

Where?

work in progress, any suggestions?

@LilKeyboard nice to hear! I propose to add R1 model into init_llms_high_intelligence() function, and Deepseek-v3 model into init_llms() function. Also please rename init_llms() to init_llms_medium_intelligence().
