OpenAI Launches GPT-4.5: Friendliest Yet

OpenAI Unveils GPT-4.5: Enhanced Human-Like Interaction

• OpenAI released GPT-4.5, priced at $75 per million input tokens and $150 per million output tokens.
• The model is 2900% more expensive to input and 1300% more expensive to output than its predecessor, GPT-4o.
• GPT-4.5 emphasizes emotional intelligence, outperforming other models in creative intelligence and conversational quality tests.
• It scores 71.4% on GPQA but still trails behind OpenAI’s o3-mini model’s reasoning capabilities.
• Available for Pro users at $200/month, with Plus users gaining access next week for $20/month.

OpenAI’s latest model, GPT-4.5, offers improved human-like interaction but comes with a significant cost increase compared to previous versions, focusing on emotional intelligence rather than enhanced reasoning capabilities.
