New Delhi: OpenAI has officially announced the general availability of the GPT-5.6 family of AI models, unveiling GPT-5.6 Sol, GPT-5.6 Terra, and GPT-5.6 Luna. OpenAI has also released ChatGPT Work for research and long-form deliverables while extending Codex capabilities for software development workflows. However, the GPT-5.6 lineup includes three models specifically designed for different workloads. GPT-5.6 Sol is a flagship model aimed at coding, knowledge work, cybersecurity, scientific research, and complex reasoning tasks.
GPT-5.6 Terra is specially designed as a balanced model for everyday workloads, while GPT-5.6 Luna is aimed at faster and lower-cost usage. GPT-5.6 unveiled an additional reasoning option for complex workflows. Max setting offers more compute time to explore alternatives, run checks, and refine responses. Ultra sets coordinates for four AI agents in parallel by default, enabling them to work on different parts of the task simultaneously.
Developers can also build similar workflows by using the beta multi-agent capability in the Responses API. Through Programmatic Tool Calling, GPT-5.6 can write and execute lightweight in-memory programs that coordinate tools, process intermediate results, monitor progress, and determine the next steps during the workflow. Programmatic Tool Calling also reduces the number of model interactions required for the tool-based tasks and supports Zero Data Retention.
The company has reported performance improvements across coding, knowledge work, agentic tasks, cybersecurity, and scientific evaluations. GPT-5.6 Sol improves computer-use capabilities by enabling the model to inspect rendered outputs rather than generating code or content. This allows it to identify visual and functional issues and refine results before completion. This model can also generate the interfaces from the natural language prompts and create interactive explanations and visualizations within the ChatGPT Work. For professional workflows, GPT-5.6 can work with data from services such as Slack, Notion, Microsoft 365, and Google Drive to create reports and other shareable content.
These models can also generate fully editable presentations from scratch, along with documents, spreadsheets, reports, and Sites. It can also follow the reference files and templates by applying layouts, typography, spacing, colors, and Slide Master rules. Advanced cybersecurity capabilities are available via OpenAI’s Trusted Access for Cyber program. Individuals can request access after identity verification, while organizations can apply for access for their teams. Individual members must enable Advanced Account Security with hardware-backed passkeys by September 1 to retain access to advanced cybersecurity models. Users without hardware-backed passkeys can receive preferred pricing from Yubico.
