OpenAI launched GPT-5.5, a new model class designed for autonomous agent workflows and complex professional tasks. Available today for Plus, Pro, Business, and Enterprise users, the model can understand multi-step goals, utilize tools, and verify its own work. It is integrated directly into ChatGPT and Codex.
This update addresses the reliability gap in agentic AI by focusing on self-correction. While GPT-5.4 introduced computer use, GPT-5.5 optimizes the underlying inference—the process of running a model—to make high-intensity reasoning practical. It transforms the model from a reactive chatbot into an iterative research partner.
You can access GPT-5.5 now through ChatGPT or the Codex desktop app. For demanding workloads, the new GPT-5.5 Pro variant offers a step change in quality for Pro, Business, and Enterprise tiers. This model is optimized for processing document context and parallel subagent workflows.
Frequently asked questions
- What is GPT-5.5?
- GPT-5.5 is a new class of intelligence from OpenAI designed for complex work and powering autonomous agents. It is built to understand multi-step goals, use external tools, and verify its own work to ensure tasks are completed accurately. It is currently available within the ChatGPT and Codex platforms for paid users.
- Who can access GPT-5.5 and GPT-5.5 Pro?
- GPT-5.5 is rolling out to ChatGPT Plus, Pro, Business, and Enterprise users. The more advanced GPT-5.5 Pro variant is specifically available for Pro, Business, and Enterprise tiers. These models are accessible through both the ChatGPT interface and the Codex desktop application, which is used for agentic software engineering tasks.
- How is GPT-5.5 different from previous OpenAI models?
- GPT-5.5 introduces full-stack inference improvements—the process of running a model to generate outputs—that allow for faster speeds and higher efficiency during complex tasks. Unlike earlier versions, it is specifically optimized to act as an iterative research partner that can check its own work and process document context.
- What are the main capabilities of GPT-5.5 for agents?
- GPT-5.5 is designed to power AI agents by handling complex goals and carrying more tasks through to completion without constant human direction. It features native tool use and the ability to check its own work, meaning the model can review its outputs for accuracy. This makes it more practical for demanding workflows.
- Is GPT-5.5 available in Codex?
- Yes, GPT-5.5 is available in Codex as part of the current rollout. Codex is OpenAI platform for agentic coding and computer-based work. By integrating GPT-5.5, Codex users can leverage the model improved reasoning and ability to check its own work to manage software development lifecycles and other multi-step technical tasks more reliably.
