OpenAI previews GPT-5.6 Sol

OpenAI is previewing the GPT-5.6 model family, debuting the flagship Sol model along with Terra and Luna for lower-cost everyday workflows. Access is currently limited to trusted partners in coordination with the U.S. government to test safety safeguards.

// ANALYSIS

This staged, government-coordinated preview signals that frontier model releases are becoming as much about defense-sector vetting as consumer capabilities. OpenAI is steering toward agent-based computing rather than just single-turn text completion.

–Flagship Sol features 'Max Reasoning Effort' and 'Ultra Mode' which uses multiple subagents to solve complex multi-step workflows
–Sol sets new SOTA results on Terminal-Bench 2.1 for command-line tasks and ExploitBench/ExploitGym for cybersecurity
–Lower-tier Terra offers GPT-5.5 performance at half the price, while Luna targets low-cost high-speed execution
–The limited preview starts with 20 trusted partners to pressure-test cyber, biology, and other safeguards
