From the Jul 17, 2026 daily brief

Databricks benchmarked models on engineering tasks against its own multi-million-line codebase: Sonnet 5 is about 1.7× cheaper than Opus 4.8 per token, yet costs more per completed task — $2.09 per task for Sonnet 5 versus $1.94 for Opus 4.8 — because the cheaper model retries more rounds and completes 6 percentage points fewer tasks (Databricks blog, 2026-07; The Register also covered it independently on 07-13). The one-line takeaway for buyers: compare cost per completed task, not the sticker price.
