Overview

• OpenAI's GPT-4.5, its largest AI model to date, has launched but is receiving mixed reviews due to high costs and limited improvements over previous models.
• The model's pricing is significantly higher than its predecessor, costing $75 per million input tokens and $150 per million output tokens, making it impractical for many developers.
• CEO Sam Altman revealed that GPU shortages have delayed the rollout, with additional hardware expected to ease availability in the coming weeks.
• While GPT-4.5 introduces more conversational and intuitive interactions, it lags behind competitors like Anthropic's Claude 3.7 Sonnet in reasoning and efficiency benchmarks.
• OpenAI is shifting focus toward simulated reasoning models like o3, signaling a potential pivot away from traditional large language models in future developments.
