OpenAI has announced the launch of GPT‑5.5—the most advanced version of artificial intelligence for professional use. The new model is geared towards programming, data processing, and scientific research tasks, offering high speed and efficiency. According to the company, GPT‑5.5 can independently perform complex multi-step tasks, plan actions, use third-party tools, and verify its own results without requiring constant user supervision.
Unlike previous versions, GPT‑5.5 demonstrates a notable increase in performance in so-called agent programming, office process automation, and data analysis. The model successfully handles coding and debugging, searching for information online, creating documents and spreadsheets, as well as managing software until the task is fully completed. A key difference is its ability to process unstructured and complex queries, which helps accelerate the completion of intricate projects.
Speed and efficiency
Despite increased cognitive capabilities, GPT‑5.5 maintains the processing speed of GPT‑5.4, which is especially important for enterprise users and developers. The model requires fewer tokens to perform typical programming tasks, reducing costs and improving overall efficiency. According to tests, GPT‑5.5 outperformed GPT‑5.4 on the key benchmarks Terminal-Bench 2.0 and SWE-Bench Pro, delivering better results with lower resource consumption.
Security and control
OpenAI notes that GPT‑5.5 is equipped with the most powerful set of safety mechanisms in the company’s history. Before launch, the model underwent comprehensive internal and external security assessments, including resilience testing against cyber threats and biological risks. Both internal experts and independent specialists were involved in the development and evaluation, while feedback came from nearly two hundred partners who received early access to the system.
Separate control measures are provided for different access channels. In ChatGPT and Codex, the model is already available to Plus, Pro, Business, and Enterprise subscribers, while GPT‑5.5 Pro is available for Pro, Business, and Enterprise. Additional security measures are being introduced for the API, and OpenAI is negotiating requirements for large-scale implementation with partners. GPT‑5.5 and GPT‑5.5 Pro are expected to be available in the API in the near future.
Applications in business and science
GPT-5.5 is actively used within the company to automate processes in engineering, finance, communications, marketing, data analysis, and product management. In the scientific field, the model has demonstrated significant progress in multi-step data analysis, bioinformatics, and mathematical calculations, enabling faster research and the achievement of new results.
The model runs on modern servers with NVIDIA graphics processors, ensuring high text generation speed without loss of quality. To protect critical infrastructure, OpenAI cooperates with government agencies and expands access to GPT-5.5 through verified programs.
The cost and terms of use depend on the selected plan, and detailed data on tests and comparative indicators are available in OpenAI’s official materials.
