The GPT-4 wall was the [[phenomenon]] that [[large language model|large language models]] available publicly between early 2023 ([[GPT-4]]'s public release) and 2025 were not significantly more [[generally capable]] than the original GPT-4 itself. Despite massive advancements in cost optimization, much wider availability of GPT-4-level models and better [[median user preference tuning]], frontier models during the wall period were not significantly better at certain hard tasks, and could sometimes be seen as downgrades relative to GPT-4.
