“It’s a lemon”—OpenAI’s largest AI model ever arrives to mixed reviews
SMRTR summary
OpenAI's GPT-4.5 model disappoints with high costs and limited improvements over GPT-4. Priced at $75-$150 per million tokens, it's impractical for many applications, while newer models like o3-mini offer better performance at lower costs. This signals a shift towards simulated reasoning models and alternative AI architectures, with GPT-4.5 likely marking the end of traditional large language models.
