Claude Extended Thinking: how budget_tokens, thinking blocks, and streaming work — with accuracy benchmarks and real cost numbers for Sonnet and Opus.

Claude Code told you it wrote the file. It told you the push succeeded. You moved on. Hours later you...

Sonnet 4.6 ($3/$15) vs Opus 4.7 ($5/$25): real performance gaps, 5 workloads where Opus ROI is positive, 4 cases where Sonnet wins on cost.

Z.ai shipped GLM-5.2 as open weights (MIT) in June 2026, and it matches Claude Opus 4.8 on real coding-agent tasks at a fraction of the per-token price. This is the builder\'s read: what actually ship
