100-word summary
OpenAI released GPT-5.4 today with native computer-use capabilities, meaning it can navigate apps and operate your desktop without middleware. The model also plans its approach before diving in, searches the web more effectively, and handles 1 million tokens in Codex (versus 272K in standard API). What you can actually do: let it draft and edit spreadsheets or presentations with fewer rounds of cleanup, or build agents that complete multi-step tasks across different programs. It uses fewer tokens per task than GPT-5.2, which should cut API bills. The catch: OpenAI is phasing rollout with admin controls because the model's cyber capabilities are strong enough to need active monitoring.
