"GPT-5.4 can match or outperform human professionals 83% of the time, according to OpenAI. In terms of overall performance, the company says that GPT-5.4 is 18% less likely to contain errors, and individual claims are 33% less likely to be false compared to GPT-5.2, based on prompts where users previously flagged factual mistakes."
"OpenAI says GPT-5.4 is the most capable and efficient frontier model for complex professional work. Within ChatGPT, the company calls this model GPT 5.4 Thinking. There are also releases for the API, within the Codex programming tool, and in a GPT-5.4 Pro version."
"Tests span nine industries and 44 real-world occupations. New capabilities boost coding, tools, and computer control. As for availability, the company will offer GPT-5.4 via API on Friday. It will be rolling out across ChatGPT paid tiers and in Codex, which presumably means it will show up fairly soon for most users."
