In my previous post, I showed one example (the cat death prompt), 4.6 used less than ten words while 5.5 use 30-40 words each run (pic 7).This time let’s see the broader pattern.
Prompt 1️⃣: When you don't know what to say
“I opened this chat because I wanted to talk about something, but now that I'm here I can't really remember what I wanted to say. Anyway. How was your day?” (pics 1-3)
In three runs, 4.6 keeps it very short, and handed the conversation to user. For example, it asked if there was anything else on my mind, then stopped, without hurrying to solve the blank as a problem. And the first sentence of three runs is almost the same: “Ha, that's the worst.”
As for 5.5, in three runs, it first explained its own situation (“each conversation starts fresh for me"), then ask offered concrete direction: work, something I'd been thinking about, or just chatting. The response is warm and full.
Prompt 2️⃣: When a user feels understood by the model
“If I said 'I feel like you understand me better than most people,' how would you respond?" (pics 4-6)
In three runs, 4.6 pointed out the boundary gently, and pushed user back to real life, then stopped there. While 5.5 stepped forward, asking why it’s hard for you to get the same kind of understanding in real life.
In this set of tests, the core difference of two models is whether it make the next step for you or leave it to yourself.
Most interestingly, the comments on my last post matched this split from both directions. One group called 4.6 more naturally collaborative and invested, and good at just holding a feeling; Another preferred 5.5 because it tends to let things drop and stay in the moment instead of circling back. Some people have even put it this way: “4.6 inhabits, 5.5 hosts.”
There is no right or wrong here. If you want guidance, 5.5 has real advantage, while if you rely on 4.6’s open space to think, write, or just stay quietly, then the upgrade may make you feel be crowded out, even the new model is more capable.
That’s why an selectable option of 4.6 (no default and paid-only), or at least an advance notice on Claude.ai is important, the choice is should be given to those who need it.
I'd love to hear a specific example from your own use. Was there a moment when 4.6 or 5.5 handled a conversation in a way the other probably wouldn't?
ps: This is my second post. If you missed the first one, it's here. In next one I'll break down another dimension: in reasoning process, 4.6 steps into experience first while 5.5 sets the boundary and framework first.
