Afraid of Using the Wrong LLM. ChatGPT 5.5 waterdown, Gemma Struggles

Hi, I’m having a very hard time right now. I used to use ChatGPT 4o and 5.1 Thinking for helping me write my story, and I was very happy with them. Every day was feeling and passionate about my love for the story and characters, and I felt like I was conveying the message and themes I wanted to explore with the story with confidence. But ever since ChatGPT removed both models, the models that came after, 5.4T and 5.5T (I didn’t even touch 5.2 or 3.), I feel like the responses are much stiff and less emotionally-oriented.
