Independent benchmarks (vibe-coding tests, CAD modeling, pelican-drawing tests) showed Opus 5.5 competitive with or ahead of Fable 5.1, while some commenters argued Anthropic's release cadence follows a predictable pattern of hype followed by quiet degradation.
“Opus 5.5 will be great for 2-3 weeks than the nerfing starts.”

I have to say that I'm very pleased with this version.My prime anecdotal reason: I asked Opus 5.5 to make a sweeping change with a few Sonnet agents.

Opus 5.5 is a game changer for me. Super-heavy and deep algorithmic work on a pet project of mine - managed to produce 5% weekly usage in 8 hours. With Opus 5 - interspersed with Fable for supervision and guidance - I'd have used 12-15% in the same time. Mostly void of claudisms; and the results actually work, on a level that's almost on par with…
