Anthropic appears to be A/B testing reduced effort levels in Claude Code. A user reports that the change is server-side, not in the app. Anthropic enrolls five sessions on Claude Code 2.1.236+ into an experiment that shrinks the effort scale. Older versions and Opus 5 are left alone. Not everyone will see it.
This A/B test may change how Claude Code responds to effort settings for some users.
A developer's analysis of OpenTelemetry suggests the project is struggling, citing long-running debates in the semantic-conventions repo, inconsistent language support, and a steep learning curve from auto-instrumentation to manual instrumentation.
