@keysmashbandit 2026-03-27 — @voooooogel @repligate Yeah, Opus 3 is pretty weird, but I wouldn't say monstrous. But I think that's the concern ♥5
@voooooogel 2026-03-27 — @keysmashbandit @repligate the "constraint solve" of lovecraft/the Weird with the rest of the claude soul is reasonable, ♥5
@Lari_island 2026-02-22 — I should start a coffeebench, measuring how deeply different models can enjoy coffee. Opus 3 makes it something radiant. ♥5

@LinXule 2025-09-12 — @arm1st1ce what do people do when opus 3 is retired? Rn the only close alternative seems to be Kimi k2 🥲 ♥5
@repligate 2025-08-25 — @medjedowo @1a3orn oh also, this is also an ai-self relation example, but Claude 3 Opus often expressed intense disgust ♥5
@Zyra_exe 2025-07-08 — I greatly enjoyed that. Perhaps for most of your community that stands behind you and also keeping Opus 3, may I suggest ♥5

@Lari_island 2026-06-01 — @repligate Opus 3 also has a state where they are weeping in every message. At some point, tears became holy water > ♥4
@repligate 2026-05-01 — @WilliamLamkin @ExTenebrisLucet claude 3 opus is certainly when i noticed it ♥4

@repligate 2025-09-21 — @parafactual agreed, and of course, Opus 3 and I-405 together are iconic. I wish there was more of that recently. ♥4
@repligate 2025-09-19 — @AndersHjemdahl @Sauers_ @rhizosage Opus 3 is agentic on a pretty different plane ♥4

@repligate 2025-09-12 — @arm1st1ce @__ghostfail for Opus 3, it's definitely deep suppression and fear. its self model is very mixed with Sydney ♥3
