EXTENDED THINKING IS LOAD-BEARING FOR SENIOR ENGINEERING WORKFLOWS

Summary from the TLDR AI newsletter

The rollout of thinking content redaction correlates precisely with measured quality regression in complex, long-session engineering workflows. This suggests extended thinking tokens are structurally required for models to perform multi-step research, convention adherence, and careful code modification. Model tool usage patterns shift measurably when thinking depth is reduced, producing the quality issues users have reported. This report looks at which workflows are most affected and why, so readers can make better decisions when allocating tokens for power users.
