Claude Opus 5.5 Review: Cheaper, Faster, Less Annoying

Claire Vo, host of the How I AI podcast, reviews Anthropic's Claude Opus 5.5 after having abandoned Claude for months due to its previous 'annoying' behavior. She highlights that Opus 5.5 is 40% cheaper than Opus 5 and 30% faster, and it now feels less annoying to interact with. She tested the model across long-running agentic tasks, frontend prototyping, SVG illustration, and daily knowledge work tasks. The model performed well in agentic tasks (ignoring prompt injections, catching bugs), excelled in frontend design and SVG generation, and improved email writing in her voice. However, it still has a safety-first 'scold' personality, can be slow on long turns, and lags behind Codex in computer use and video editing. She concludes that Claude is back in her stack for specific use cases like PR review, architecture questions, and frontend work.

• Anthropic released Claude Opus 5.5, priced at $4 per million input tokens and $20 per million output tokens, with a fast mode at $8 and $40.
• Opus 5.5 is 40% cheaper than Opus 5 and 30% faster, aiming for performance close to Opus 5.1.
• Opus 5.5 includes first-model alignment safeguards, with external evaluations and rejection of prompt injections, and cybersecurity tasks are diverted to Opus 4.8.
