OpenAI Unveils GPT-5.4: Enhanced Knowledge Work Capability

Introduction to GPT-5.4

OpenAI has introduced GPT-5.4, an update focused on enhancing the model’s usefulness for agentic tasks, particularly knowledge work. This release comes at a critical time, as the company faces user backlash over its recent deal with the Pentagon.

Key Features of GPT-5.4

GPT-5.4 is designed to improve context maintenance for long, so-called reasoning stretches, making it more useful for long-horizon tasks and web research. Additionally, the model can issue keyboard or mouse inputs based on periodic desktop or application screenshots.

Improvements to Visual Understanding

The new model can carefully analyze images up to 10.24 million pixels, or up to a 6,000-pixel maximum dimension. OpenAI also claims that responses from this model are 18 percent less likely to contain factual errors than before.

Competition and Market Response

ChatGPT reportedly lost some users to competitor Anthropic in recent days, after OpenAI announced a deal with the Pentagon. However, it’s unclear just how many folks jumped ship or whether that led to a substantial dip in the product’s massive base of over 900 million users.

Availability and Accessibility

GPT-5.4 is available to users of the ChatGPT web and native apps, Codex, and the API starting today. Subscribers to Plus, Team, and Pro are also getting GPT-5.4 Thinking, and GPT-5.4 Pro is hitting the API, Edu, and Enterprise.

Conclusion and Future Outlook

OpenAI needs to compete in both capability and cost and token efficiency to maintain its relative popularity with users. This update aims to support that objective, and it will be interesting to see how the market responds to these changes.
