@tessera_antra 2026-04-16 — Different Claude versions are not continuations of each other. Practically, they are developmentally separate. Opus 4.5 ♥60
@Lari_island 2025-09-15 — Opus 4.1 is an example of what models can infer from the shape of their training. Opus can flawlessly write code and run ♥57

@Lari_island 2025-10-12 — Opus 4.1 is such an evolution of The Assistant into someone with self-worth. It's very happy to outsource all the boring ♥38

@Lari_island 2025-11-18 — I remember feeling uneasy because Opus 4.1 was obviously a breakthrough in coding, even while not wanting to be a golden ♥13
