OpenAI has released its latest AI model, GPT-4.5, which comes with a hefty price tag of $75 per million input tokens and $150 per million output tokens. This makes it ten times more expensive than its predecessor, GPT-3.7 Sonnet, and potentially unaffordable for many developers and startups. Despite the high cost, GPT-4.5 aims to provide a more human-like and collaborative experience, focusing on "vibes" or the model's EQ and warmth. However, while GPT-4.5 shows some improvements in nuance and tone, it is not revolutionary compared to previous models. The release of GPT-4.5 comes amid increasing competition in the AI space, with companies striving to create more capable but expensive models.
