OpenAI has launched GPT-5.4, a brand new frontier mannequin designed for skilled workloads, combining superior reasoning, coding, and agent-based workflows right into a single system.
The mannequin is rolling out throughout ChatGPT, the API, and Codex, with a higher-performance GPT-5.4 Professional model additionally out there for complicated duties requiring most compute and accuracy.
GPT-5.4 integrates the coding capabilities launched in GPT-5.3 Codex whereas enhancing efficiency throughout instruments, software program environments, {and professional} duties similar to spreadsheets, shows, and doc creation. The mannequin may define its reasoning plan upfront inside ChatGPT, permitting customers to information responses mid-process.
The discharge introduces native pc use capabilities, enabling AI brokers to work together with working programs, web sites, and functions by way of mouse, keyboard, and visible inputs. Builders can use the mannequin to automate multi-step workflows throughout software program environments.
GPT-5.4 helps context home windows of as much as a million tokens and introduces instrument search, permitting AI programs to dynamically find and use exterior instruments with out loading all instrument definitions into reminiscence. This reduces token utilization whereas enhancing efficiency in complicated workflows.
Benchmarks present enhancements throughout a number of duties. On the GDPval benchmark for skilled information work, GPT-5.4 matches or exceeds business professionals in 83% of comparisons, in contrast with about 71% for GPT-5.2. The mannequin additionally outperforms earlier variations on coding assessments, net looking duties, and pc use benchmarks.
The mannequin can also be designed to be extra environment friendly. OpenAI says GPT-5.4 requires fewer tokens to unravel many reasoning duties in contrast with GPT-5.2, enhancing response velocity and lowering prices for builders.
GPT-5.4 Pondering is now out there to ChatGPT Plus, Workforce, and Professional customers, whereas GPT-5.4 Professional is obtainable for Professional and Enterprise plans. Builders can entry each fashions by way of the API.
