Hot take on OpenAI's new GPT-4o – by Gary Marcus


Gary Marcus offers a critical perspective on OpenAI's latest release, GPT-4o. Acknowledging the improvement in speech synthesis, he notes its similarities with its predecessors and points out the lack of significant advancement beyond GPT-4. The presence of quirky errors and hallucinations in GPT-4o's output suggests that the AI has not notably evolved. Marcus implies that this stagnation in significant capability advances might signal a broader trend of diminishing returns in AI development.

  • OpenAI released GPT-4o, showing slight upgrades but not GPT-5.
  • GPT-4o's speech synthesis improvement is compared to Google Duplex.
  • No GPT-5 suggests possible diminishing returns in AI progress.
  • GPT-4o displays quirky errors similar to earlier versions.
  • Marcus remains skeptical of exponential AI improvement claims.
