Best roleplaying AI?

Hey guys! Can someone tell me the best ai that is free for some one on one roleplay? I tried chatGPT and it was doing good at first but then I legit got to a scene and it was saying it was inappropriate when literally NOTHING inappropriate was happening. And no matter how I tried to reword it chatGPT was being unreasonable. What is the best roleplaying AI you found that doesn't do this for literally nothing?
