OpenAI officially released the GPT-5.4 and GPT-5.4 Pro models, supporting context windows of up to 1 million tokens. The new models offer a "thinking" mode, optimizing workflows for professional tasks such as spreadsheets, presentations, and document processing, and allowing users to adjust task direction during the response process. GPT-5.4 achieves native-level "computer operation" capabilities for the first time, supporting agents in executing complex workflows across software, significantly improving reasoning efficiency and response speed
