Official release notes

  • Planned custom GPT retirement → plugins migration (help note dated 2026-09-11): Custom GPTs are slated for retirement across ChatGPT plans, with a migration path to plugins (reusable instructions + connected apps). Existing GPTs remain usable until each plan’s retirement date; users should inventory GPTs/creators/access and validate migrated plugins when available. Details: planned retirement.

Flags / experiments

  • Ads / tone: added dynamic_ad_rewrite_enabled, connection_tone.
  • Instruction packs cleaned up: removed a cluster of prompt/instruction flags (appConnectionInstructions, artifactInstructions, baseInstructions, browserInstructions, dailyBriefingInstructions, emailMessagingInstructions, onboardingInstructions, skillInstructions, websiteInstructions, writingStyleInstructions, writingStyleSetupInstructions) plus tax_types.
  • Statsig (opaque): +1 gate, −3 gates, −3 dynamic configs; layers unchanged.

No other high-signal product-surface launches (Projects, Voice, message queue, nav, Imagine/media, connectors) in this diff.
