Anthropic launched Claude Sonnet 5 with 1M context, 128k output, introductory pricing, and no Priority Tier.
The read
The operational delta is long context and high output inside Sonnet, with Priority Tier unavailable.
The frame
It sits next to Sonnet 4.6 feature parity, except Priority Tier, so builders keep the same tool surfaces.
