Report claims Claude Code default cost rose with Sonnet 5

Category: Agentic coding
Status: discussion
Sources: analysis
Summary: A blog post argues that Claude Code became substantially more expensive after Sonnet 5 shipped and became the default, framing the change as a roughly 5x cost increase for typical usage. The figure is the author's estimate, not an Anthropic pricing statement, and depends on model selection and usage pattern.
Why it matters: Default-model and pricing changes in a widely used coding agent directly change per-seat cost for teams that do not override the model.
