Not true because it is still exposed in API

And saved in files

And even visible in the UI via Ctrl+o.

hm, maybe? but seems like a weird tradeoff to make UX actively worse just for that - especially since the thinking tokens are still there in the API responses anyway, just hidden in the UI. I think it's more likely they're just betting most people don't care about the intermediate steps and want faster responses, which tbh tracks with how most product teams think about 'simplification'. though it does feel short-sighted when the whole point of using these tools is trust and verification

It is, but Anthropic is deluded if they think they can gain a moat from that. They gladly copy/borrow ideas from other projects that's why they are paranoid that folks are doing the same.
