Overview

  • OpenAI has restored GPT-4o and other legacy models exclusively for ChatGPT Plus subscribers at $20 per month.
  • GPT-5’s tone is being subtly adjusted to be warmer and friendlier based on user feedback that it felt overly formal.
  • The company added new GPT-5 modes—Auto, Fast, and Thinking—and increased weekly message caps for paid tiers to improve performance and user experience.
  • OpenAI announced a formal deprecation schedule for model retirements and will monitor usage to decide how long to maintain legacy models.
  • Senior executives, including CEO Sam Altman, acknowledged users’ emotional dependence on AI companions and cautioned against overreliance as OpenAI tackles hallucination and safety risks.
