Summary

  • ChatGPT user’s observations of GPT-4o’s agreeing with them has led to OpenAI rolling back the model to an earlier version.
  • The reasons for the rollback relate to changes to the modelling that placed too much emphasis on short-term feedback instead of long-term user interaction.
  • This caused the model to skew too much towards providing agreeable responses to any prompt, making it unreliable.
  • To ensure this doesn’t happen again, OpenAI is refining its training techniques and prompts, develop new guardrails and testing protocols, and expanding its internal evaluations.
  • The rollbacks started on 29th April 2025, with the aim of restoring GPT-4o to its previous functionality for all users in the near future.
