Claude Sonnet 4.6 raises bar for developer workflows

This looks like a meaningful model-tier shift, not a minor patch, because Sonnet-class pricing is now paired with near-Opus-class behavior on many practical dev tasks.

• –Anthropic positions Sonnet 4.6 as the default for Free and Pro users, signaling confidence in production readiness.
• –Early preference metrics and demo behavior both point to fewer dead ends during multi-step coding loops.
• –The 1M-token context beta is especially relevant for large-repo refactors, long traces, and cross-file reasoning.
• –Keeping pricing aligned with Sonnet 4.5 increases pressure on competing coding-focused model offerings.
