Claude Sonnet 5.5 arrives: Anthropic’s AI for work is now 30% faster

Anthropic has just unveiled Claude Sonnet 5.5, the new generation of Claude within its mid-range lineup. The improvement in this version is faster and more efficient, since its responses are more than 30% faster and token usage is substantially lower.

More speed for everyday work

Sonnet 5.5 is designed for well-defined tasks: fixing code errors, preparing documents, creating presentations, or working with spreadsheets. According to Anthropic, the new version keeps Sonnet 5’s price of $2 per million input tokens and $10 per million output tokens, but completes many of the tasks using quite a few fewer tokens. In practice, we can get more work done with the same budget.

Anthropic has been turning Claude into a tool increasingly work-focused for months. We’ve already seen how Claude Code can manage multiple sessions and how claude.ai has sped up considerably. Sonnet 5.5 is one more step in this evolution that, according to the company, offers cybersecurity capabilities comparable to those of Opus 5.

Its arrival coincides with the recent releases of OpenAI’s GPT-6 Sol and Luna. With each generation, AI companies seek to deliver better performance at a lower cost while improving integration. A path that makes AI increasingly ubiquitous, although that has its risks.
