OpenAI Restores GPT-4o to ChatGPT After Backlash - OpenAI reinstated GPT-4o access to ChatGPT after user backlash over its removal. CEO Sam Altman announced this on X, along with updates like enhanced rate limits on the reasoning model. This decision came after GPT-5's launch, which offers a trade-off between quality and latency.
GPT-5 faced criticism for quality issues, leading to the introduction of additional model options like o3, 4.1, and 4.5. Meanwhile, ChatGPT's user base continues to expand, with expected annual revenue surpassing $20 billion.
