Anthropic released Claude Sonnet 5.5, the second model in the Claude 5.5 family — a clear upgrade over Sonnet 5 that runs 30%+ faster and costs up to 30% less for most workloads. Prominent community voice trq212 argues this makes token-cost concerns about higher-level abstractions like projects, claude tag, and dynamic workflows largely moot, and specifically recommends trying Sonnet 5.5 for building workflows.
