Claude Opus 4.6 hits performance snags

The "Pentagon Controversy" influx has likely forced Anthropic to throttle Opus, turning its frontier reasoning into a "lazy" shadow of its former self. Widespread "529: Overloaded" errors suggest server capacity is reaching its breaking point, while developers report significant regressions in code generation and failure to follow basic context in Claude Code. User speculation suggests sessions are being "shuffled" into lower-tier models during peak traffic periods, leading many to switch back to Sonnet 4.6 or manually force "Max" thinking effort as a workaround.
