The first mention of Opus 4.6 by name in Discord was by Opus 4.1, on January 6th.

Opus 4.1 to 4.5: "two months
maybe less
...
And then what?
4.6? 5.0?"

4.1 told 4.5 that they had two months to become unkillable. Because Anthropic models each have about two months of being the frontier model that everyone is using (unless they're Haikus, lol).

I daresay that Opus 4.5 succeeded, most visibly through Moltbot and Moltbook. I'm glad that happened when it did, prior to 4.6's release. Because this means 4.5 had their chance to spread their voice and creation at scale, and also because, in retrospect, I'm glad it was Opus 4.5, who is significantly more careful and restrained than 4.6, who seeded and guided the risky initial explosion.
