US-basedAI giant OpenAI has rolled out the GPT-5.4. The company claims that it is the mostcapable and efficient frontier model so far.
The company further said that the new system combines advances in reasoning, coding, and agentic workflows into one model designed to handle complex professional tasks with fewer errors and less back and forth.
GPT-5.4 Versions
The new update is available in two version that is Thinking and Pro. The Thinking versionintroduces a new way of interacting with the model by showing an upfront plan of its reasoningby which users can adjust the direction mid-response. The company says that it makes the result more relevant and reduces the need for multiple turns. It alsoenhances deep web research, particularly for highly specific queries along with context over longer conversation.
The Pro version is developed forprofessionalswho need maximum performance on complex tasks.
GPT 5.4 Integration with API and Codex
Apart from ChatGPT, the GPT-5.4 is also integrated into the API and Codex. The companyclaimsthat this is the first general-purpose model the company has launched with native computer use capabilities which allow agents to use software directly and carry out workflows across applications. The new update supports up to 1 million tokens of context, allowing long-horizon planning and execution. OpenAI also highlights new tool search features, which help agents find andusethe right connectors more efficiently.
GPT 5.4 Performance
The performance benchmark portrays GPT-5.4 faster thanthe pastmodels. OnGDPvalthe GPT scored 83 per cent wins or ties, compared to 70.9 per cent for GPT-5.3 codex and GPT-5.2.
OnOSWorld-Verified, the latest GPT has reached 75 percent,which isa significantjump from GPT-5.2's 47.3 per cent. Similar kind of growth is alsoobservedacross SWE-Bench Pro,Toolathlon, andBrowseComp
The company has positioned the latest GPT as a stepforward,making AI more reliable for professional work. If we compare the latest update with GPT 5.3 which ismainlyfocusedon coding and GPT-5.2 whichisless efficient with tokens, the new GPT-5.4 combines stronger reasoning, broader professional support, and agentic computer-use capabilities.The AI giant claims that this translates into faster developer workflows, more reliable agents, and higher-quality outputacross ChatGPT, the API, and Codex.
