Answer

Anuttar Devas are traditionally placed in the 4th gunasthana, called Avirata Samyagdrishti — that is, right faith but not full vows. Jain texts on the Anuttara gods say they “all have true belief” and are “only on the 4th gunasthana.” ( jainworld.jainworld.com)

Explanation

This means they have right belief, but they are not yet at the stage of complete renunciation like monks. Among the five Anuttara vimanas, the highest is Sarvarthasiddha, which is regarded as the last heavenly birth before liberation. ( jainworld.jainworld.com)

Takeaway

So, in simple terms: Anuttar Devas = 4th gunasthana. ( jainworld.jainworld.com)
