There's no understanding of what is "GPT-5.4" and "GPT-5.5"

might be an ez fix.

• ChatGPT.com serve GPT-5.4 mini, GPT-5.4, GPT-5.5 Instant, GPT-5.5 Thinking, GPT-5.5 Pro. No “GPT-5.4 Pro” btw.

• openrouter.ai serves GPT-5.4, GPT-5.4 Pro, GPT-5.5, GPT-5.5 Pro.

• t3.chat serves GPT-5.4 and GPT-5.5, with varied reasoning. The “knowledge cutoff” and “added on” of these 2 models don’t match any of the 4 models on openrouter.

So i don’t understand what’s going on with GPTs and what i’m using.

E.g. if i were to trust openrouter, there’s legit GPT-5.4 Pro and GPT-5.5 Pro. Are they accessible on t3.chat? If so, how?

Please make this clear in the UI. Thank you in advance.
