Claude Sonnet 5
Anthropic's 25 Jun 2026 mid-tier model and the workhorse of the Claude 5 family. It carries most of the Opus-line coding and agent quality at roughly a third of the price: SWE-bench Verified 82.4%, Terminal-Bench 2.1 68.1%, Artificial Analysis Intelligence Index 57.2. List price is $3/$15 with a 90% caching discount, but an introductory rate of $2/$10 runs through 31 Aug 2026 — worth locking in evaluation work before it lapses. 1M-token context and the same tool-use API as the flagship line. The default pick for high-volume agent work where Opus 5 or Fable 5 would be overkill on cost.
