OpenAI has launched GPT-5.4, its latest model with native computer use capabilities that allow it to operate computers and complete tasks across applications. The release represents a step toward autonomous AI agents that can handle complex jobs independently. The model includes advancements in reasoning, coding, and professional work with spreadsheets, documents, and presentations.

Researchers at GAIR-NLP have published PC Agent-E, an agent training framework that achieves a 141% relative improvement in computer use tasks starting from only 312 human-annotated trajectories. The method uses Claude 3.7 Sonnet to synthesize alternative action decisions, and the resulting model outperforms Claude 3.7 Sonnet by 10% on WindowsAgentArena-V2.
