OpenAI has announced the discontinuation of GPT-4.5 access via the API, effective July 14. Launched just in February, developers are being encouraged to switch to GPT-4.1 as the preferred alternative. The company has indicated that GPT-5.0 is not a planned successor for GPT-4.5 at this time. While GPT-4.5 demonstrated improved performance over previous models in several areas, it is also notably expensive. Despite its advanced capabilities, the company aims to focus on more cost-effective and competitive evolving models while maintaining GPT-4.5's availability in ChatGPT for premium users.
OpenAI announced that it will soon phase out GPT-4.5 via the API, encouraging developers to transition to GPT-4.1 as the recommended replacement.
The company is focusing on developing newer models like o3, o4-mini, and GPT-4.1, emphasizing their superior performance at a lower cost.
