OpenAI has launched GPT-5.4, its first model with native computer-use capabilities, alongside financial plugins for Microsoft Excel and Google Sheets.

GPT-5.4 expands the context window to 1 million tokens; the larger limit supports longer coding and research sessions.

OpenAI's GPT 5.4 autonomously controls PCs with a million-token context, enabling complex workflows in coding, analysis, and problem-solving.
