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.
