Core Insights - OpenAI announced the removal of the GPT-4.5 Preview API effective July 14, which will impact developers who have integrated it into their products [2][3] - The removal was planned since the release of GPT-4.1 in April, and GPT-4.5 was always considered an experimental product [5] - OpenAI is focusing on promoting more scalable and cost-effective models, as evidenced by the recent 80% price reduction of the o3 API [8] Pricing and Cost Considerations - The pricing for GPT-4.5 API was significantly high at $75 per million input tokens and $150 per million output tokens, making it commercially unviable [6] - The cost of NVIDIA H100 GPUs, approximately $25,000, and their high power consumption further complicate the financial feasibility of maintaining such models [6] Strategic Implications - The rapid exit of GPT-4.5 highlights the challenges of model iteration speed and external computing costs as critical factors for OpenAI's business model [11] - OpenAI's strategy appears to be consolidating resources towards models that offer better scalability and cost control, while discontinuing less successful or ambiguous products [8]
