Explore a critical analysis of OpenAI's GPT-4.5 in this 15-minute video that examines the model's performance relative to its cost. Compare GPT-4.5 with competing models like Claude 3.7 Sonnet, DeepSeekR1, o4, and o3 mini to understand why the new release may not live up to OpenAI's claims. The video breaks down the official blog announcement, pricing structure, and documentation while also providing hands-on demonstrations with the model. Learn about alternative options like Grok 3 Beta and gain insights from the GPT-4.5 System Card.
