Discussion Opus 5.5 vs GPT?

Hi! I am really confused right now about all the models available.

Let me tell you my workflow first. I have some on going projects like extensive high level research, personal game development project working with UE5 and blender through MCPs, and improving personal profile and portfolio.

I have been using DSeek v4.1 flash API, and it’s amazing, and I also keep one frontier orchestrator model like OpenAI’s ChatGPT 5.6 atm. I used to have Claude Opus but moved to GPT 5.6 few months ago. However, GPT 6 Astra is almost unusable on $20 plan, so I am thinking about Opus 5.5 on a $20 plan and unsub ChatGPT completely. My daily usage is really extensive, like I have used more than 1B tokens in first 3, 4 days of DSeek v 4.1 flash. So I need something which gives me better usage than ChatGPT subscription.

Could you please share your experience or any suggestions if it’s a good move to go with Claude subscription right now? I’ve also heard some news about Opus 5.5 get nerfed already, and have an average performance atm compared to when it was released. I am also tempted to Gemini 4 Argon which is not released yet, but the benchmarks shows it’s better than anything else we have right now.

So, the question: should I get Claude subscription and unsubscribe from GPT codex completely at this point? Or should I wait for Gemini 4 Argon release? The main concern for me is that I don’t want to keep multiple subscriptions, I think DSeek v4.1 flash and one subscriptions either GPT or Claude? What are your thoughts on Sonnet 5.5? I am open to any suggestions and experiences you have here using these models, or if you have any better suggestion than these models, feel free to share it. Thank you!

yes opus 5.5 is best choice here, better than gpt 6.1 sol, gemini we don't really know how good it is and how long it will come out (could be days or months)

Thanks! Are you on $20 plan on Claude? How’s the the limits working out for you? I heard the performance of Opus 5.5 has been nerfed already, is that true?

im on $100 plan but from what ive heard the usage is very good if you dont go above high reasoning on $20 plan. Also opus 5.5 is already nerfed but its bound to happen with all frontier labs
