OpenAI introduces GPT-5.4 with more knowledge-work capability

In keeping with its recently accelerated release cadence, OpenAI has shipped GPT-5.4 (including GPT-5.4 Thinking and GPT-5.4 Pro).

This update comes at a critical time, as recent events have led some vocal users to abandon ship for competing products and models from Anthropic and Google.

GPT-5.4 is another model update focused on usefulness for agentic tasks, particularly knowledge work. OpenAI says this is its first model explicitly aimed at computer-use tasks; like competing models, it can issue keyboard or mouse inputs based on periodic desktop or application screenshots.

When prompted within ChatGPT, the GPT-5.4 Thinking model will present more of its reasoning up front and can accept prompts to change course in the middle of its reasoning process, OpenAI says. It’s said to improve context maintenance for long, so-called reasoning stretches. That makes it more useful for long-horizon tasks and web research.
