2026-10-24-github-copilot-cli-gpt-5-responses-requests-regain-model-specific-default-verbosity

GPT-5 Responses requests regain model-specific default verbosity. Model-specific default Responses verbosity now applies correctly for GPT-5 models unless session verbosity is explicitly set. No universal verbosity value or numerical token saving is stated.

Channel: tagged-release. Half: defect. Date: 2026-10-22.

Operator consequence: Recheck output-length expectations and evaluation settings after moving to 1.0.103. Set session verbosity explicitly when a comparison requires it, and record the selected model. This is a default-sensitive request repair, not evidence of improved answer correctness or lower billed cost.
