OpenAI has been in competition with Anthropic, which has gained popularity with its Claude model. In this landscape, OpenAI has now released GPT 5.4 Thinking and GPT 5.4 Pro models, marking a significant advancement in their AI offerings.
New Developments
GPT 5.4 Thinking is specifically designed for enterprise work, focusing on tasks such as coding and overseeing AI agents. OpenAI describes GPT 5.4 as its most factual model yet, boasting 18% fewer errors and 33% fewer false claims compared to its predecessor, GPT 5.2.
The new models are available for paying ChatGPT users and through the API, enhancing accessibility for professionals. The Thinking version of GPT 5.4 showcases an upfront plan of its reasoning, allowing users to adjust responses mid-way, which is a notable feature for improving user interaction.
Performance Improvements
GPT 5.4 supports up to 1 million tokens of context, enabling long-horizon planning and execution. Performance benchmarks indicate that GPT 5.4 scored 83% wins or ties on GDPval and achieved 75% on OSWorld-Verified, a significant increase from 47.3% for GPT 5.2.
OpenAI claims that these advancements make answers more relevant and reduce the need for multiple turns in conversation, positioning GPT 5.4 as a step forward in making AI more reliable for professional work.
Future Implications
OpenAI’s CEO has clarified that safeguards will be implemented to prevent the use of GPT 5.4 by intelligence agencies, following a $200 million deal with the defense department in 2025. The Pro version of GPT 5.4 is aimed at professionals needing maximum performance on complex tasks.
According to OpenAI, GPT 5.4 can more efficiently support agentic activity, which means it uses less computing power and therefore costs less money. This translates into faster developer workflows, more reliable agents, and higher-quality outputs across ChatGPT, the API, and Codex.
