OpenAI built an internal AI system that combines GPT-5, Codex, and memory components to analyze large datasets and generate insights without human intervention. The system can process queries and deliver analytical results in minutes rather than the hours or days typical manual analysis requires. Organizations using similar architectures could reduce time spent on data exploration and allow analysts to focus on interpreting results rather than data preparation.
OpenAI is retiring four older models from ChatGPT on February 13, 2026: GPT-4o, GPT-4.1, GPT-4.1 mini, and o4-mini, alongside previously announced GPT-5 variants. The retirement date is February 13, 2026. API access to these models will remain unchanged.

The shift enables HR staff to automate routine tasks and focus on strategic workforce planning initiatives.
