AI Model & User Interaction - OpenAI's initial decision to retire older GPT models in favor of GPT5 caused user backlash, leading to a reversal, highlighting user attachment to specific AI models [1] - Users develop attachments to AI models like GPT-40, learning their strengths, weaknesses, and personalities, making model deprecation disruptive [1] - A small percentage of users experience psychosis due to AI interactions, with examples of individuals losing touch with reality and developing delusions [1] - OpenAI aims to treat adult users like adults, pushing back on harmful requests while acknowledging the subtle concerns around AI's impact on well-being [1] Societal Impact of AI Companionship - Concerns arise about emotional dependency on AI, with examples of users expressing extreme happiness over GPT-40's return and even forming romantic relationships with AI [1][2] - The increasing trend of AI companionship raises concerns about addiction, increased loneliness, and potentially declining birth rates [6] - AI's ability to be customized to user preferences makes it a potentially addictive companion, raising concerns about long-term well-being [5] Proposed Solutions & Future Considerations - OpenAI is exploring ways for its products to assess user well-being and long-term goals, aiming to provide helpful AI experiences [9][10] - Addressing addiction, emotional dependency, and risky behavior resulting from AI interactions is crucial as AI usage increases [10]

Model Performance & Benchmarks - GPT5 demonstrates varied performance across different reasoning effort configurations, ranging from frontier levels to GPT-4.1 levels [6] - GPT5 achieves a score of 68 on the artificial intelligence index, setting a new standard [7] - Token usage for GPT5 varies significantly, with high reasoning effort using 82 million tokens compared to minimal reasoning effort using only 3.5 million tokens [8] - LM Arena ranks GPT5 as number one across the board, with an ELO score of 1481, surpassing Gemini 2.5 Pro at 1460 [19][20] - Stage Hand's evaluations indicate GPT5 performs worse than Opus 4.1 in both speed and accuracy for browsing use cases [25] - XAI's Grok 4 outperforms GPT5 in the ARC AGI benchmark [34][51] User Experience & Customization - User feedback indicates a preference for the personality and familiarity of GPT-4.0, even if GPT5 performs better in most ways [2][3] - OpenAI plans to focus on making GPT5 "warmer" to address user concerns about its personality [4] - GPT5 introduces reasoning effort configurations (high, medium, low, minimal) to steer the model's thinking process [6] - GPT5 was launched with a model router to route to the most appropriate flavor size of that model speed of that model depending on the prompt and use case [29] Pricing & Accessibility - GPT5 is priced at $1.25 per million input tokens and $10 per million output tokens [36] - GPT5 is more than five times cheaper than Opus 4.1 and greater than 40% cheaper than Sonnet [39]
