I left Claude for months. Opus 5.5 is why I'm back

Claude Opus 5.5 marks a significant improvement in user experience, effectively addressing the verbosity and "annoying" personality traits that previously led to the abandonment of earlier Claude models. This iteration delivers frontier-level performance at a 40% lower cost and increased speed, making it a viable tool for complex agentic tasks, including inbox triage and backend feature development. While the model excels at frontend design, generating sophisticated UI prototypes and SVG illustrations, it remains somewhat conservative, occasionally triggering safety-related refusals. Despite its strengths in coding and visual tasks, it still faces challenges with creative video editing and maintains a distinct, sometimes overly cautious, personality. Ultimately, Opus 5.5 earns a place back in the development workflow, particularly for PR reviews and architecture planning, though it continues to coexist with other models like Codex for specialized use cases.
