exomlapi.com [ai] [text generation] [conversation]

/*
    base        : https://exomlapi.com/
    fungsi      : ai text completion,
    note        : skrep ini cuma support teks doang, tapi bisa conversation
                  otak atik aja param di fungsi ai.generate()
                  maaf kalau parsing hasil nya kadang kurang pas, cek di
                  variabel yang namanya anu. tapi gw coba udah lumayan sih :v
                  oh ya lu bisa pilih model lain jg ai nya. cuman beberapa
                  model gw test malah ngehang.. fetch nya lama banget!
                  gw belum test semua :v, paling gw pakek yg model chat gpt
