OpenAI has decided to integrate the "o3" model into GPT-5 rather than releasing it as a standalone product, which reflects an attempt to streamline usage amidst increased competition from cost-effective models like DeepSeek. Sanchit Vir Gogia of Greyhound Research highlights that many organizations prefer simple pricing and integration to avoid the complexities of tiered costs, especially in enterprise settings. He notes that while AI spending discussions are prevalent, costs can be unpredictable due to factors like customization and compliance. The merger of O-series and GPT-series is also viewed as a response to the evolving landscape of open-source AI solutions.
