Since early June, users have reported that OpenAI changed OpenAI Codex<\/a>\u2019s experimental `multi_agent_v2` workflow so the prompts and messages passed from a main agent to its sub-agents are now encrypted<\/strong>. In practical terms, the plain-text handoff details that used to appear in session logs no longer show up there. You can still see the outcomes, but not the exact internal instructions behind a task split, a mistake, or a failed run.<\/p>\n

Those same reports say the change is required for the larger GPT-5.6 Sol and Terra<\/a><\/strong> variants. The lighter Luna<\/a> model, at least for now, doesn\u2019t appear to be affected.<\/p>\n\n

If you use OpenAI Codex for more complex coding work, this matters. Once those readable inter-agent logs disappear, debugging gets harder. It can also create problems around audit trails<\/a><\/strong>, security, compliance, change management, and simple trust, especially for regulated teams, sensitive codebases, and customer-facing systems.<\/p>\n\n

OpenAI hasn\u2019t given a direct reason for the change beyond broad documentation about encryption at rest and in transit<\/strong>. So the guesses have filled the gap: model distillation, unauthorized API pooling, data harvesting, or an effort to protect proprietary orchestration methods.<\/p>\n\n
