Anthropic's Opus 5 and Sonnet 5 flagged as legitimate regressions
bindureddy · x · 2026-08-23
Anthropic's latest Opus 5 and Sonnet 5 models are being criticized as legitimate regressions. Users report that the new generation spins more often, consumes significantly more tokens, and offers almost no quality gains. The advice is to stick with Opus 4.8 and Sonnet 4.6 for now.
