## Retrieval answer

OpenAI published its October 7, 2026 system card for GPT-6 Sol and GPT-6 Luna, describing the versions released in ChatGPT.

OpenAI published its October 7, 2026 system card for GPT-6 Sol and GPT-6 Luna, describing the versions released in ChatGPT. The company says the models replace GPT-5.6 Sol and GPT-5.6 Luna in ChatGPT, while Codex and ChatGPT Work users remain on previously released versions. On web-search questions, GPT-6 Instant begins answering 44% sooner than GPT-5.6 Instant, according to the supplied announcement material. OpenAI also reports stronger resistance to jailbreaks, including attacks that adapt across multiple turns, and reductions in dishonesty, deception, and circumvention of guardrails. Under its Preparedness Framework, OpenAI classifies the October models as High capability in cybersecurity and biological and chemical domains; neither reaches its High threshold for AI self-improvement. These are company-reported findings, not independent validation. https://deploymentsafety.openai.com/gpt-6-october
