Feature Drop: GPT-5.5 Now Available in Omnifact

GPT-5.5 is now available in Omnifact as our most capable OpenAI model for advanced work. It gives teams a stronger option for complex reasoning, agentic coding, research, data analysis, and professional workflows that need the model to carry context across multiple steps.

Building on our recent GPT-5.4 rollout, GPT-5.5 moves the GPT-5 family forward with better planning, stronger tool use, and more reliable progress through ambiguous tasks.

Built for Longer, More Complex Work

Some tasks need more than a quick answer. Debugging a technical issue, comparing evidence across sources, preparing a detailed analysis, or coordinating a multi-step workflow all require the model to understand the goal, keep track of decisions, and continue without constant correction.

GPT-5.5 handles these situations more effectively. It can reason through messy requests, break work into steps, check its own outputs, and stay useful as the task evolves.

Key Benefits

• Stronger Agentic Workflows: GPT-5.5 can plan, execute, and verify multi-step tasks with less manual steering.
• Better Coding and Technical Support: Use it for debugging, architecture questions, code review, and complex implementation work.
• Improved Research and Analysis: GPT-5.5 can work through larger knowledge tasks, compare information, and produce clearer recommendations.
• Most Capable OpenAI Option: It now sits at the top of the OpenAI lineup in Omnifact for teams that need maximum reasoning quality.

When to Use GPT-5.5

Choose GPT-5.5 when the task has high stakes, unclear requirements, or several dependent steps. It is especially useful for strategic analysis, technical troubleshooting, complex document work, and agentic workflows where quality matters more than response cost.

For faster day-to-day tasks, GPT-5.4 mini and other lower-cost models remain strong options. GPT-5.5 gives you a premium model when the work calls for deeper reasoning and persistence.
