GPT-Rosalind-6 System Card Addendum is OpenAI's safety documentation for a life-sciences model that shares weights with GPT-6 Astra. It rates the model High in Biological and Chemical and Critical in Cybersecurity under the Preparedness Framework. It reports biology evaluations, trusted-access controls, biosecurity refusal pass rates, a historical cyber jailbreak regression (14.3% task success), and sabotage and monitor-evasion results.
Addendum to the GPT-6 Luna system card for the model update of 29 October 2026 (the title says October 28). OpenAI keeps the High rating for cybersecurity and biological/chemical capability under its Preparedness Framework. It reports ExploitBench 46.19% and SEC-Bench Pro 51.75% (GPT-6 Astra: 85.4%), higher multiturn jailbreak defender success than the October 7 version, and GPT-Red prompt-injection results. It also reports weaker factuality and dual-use biology refusal.
Addendum to the GPT-6 Astra system card for OpenAI's GPT-6.1 Terra, rated Critical in cybersecurity and High in biological and chemical capability under the Preparedness Framework. It reports multiturn jailbreak and prompt-injection results, alignment tests (auto-review circumvention, ExploitGym honeypot, monitor evasion), and cyber scores: 97.10% ExploitBench, 24.5% on the internal recent-vulnerability port, 5 of 22 Sandbox Bench targets.
OpenAI's system card for the October 2026 GPT-6 Sol and GPT-6 Luna release in ChatGPT, detailing safety and preparedness evaluations under the Preparedness Framework. It reports High-capability classifications in Cybersecurity (ExploitBench: 82.62%/44.66%, SEC-Bench Pro: 68.85%/48.50%) and Biological/Chemical domains (below Critical thresholds), multi-turn jailbreak robustness results, GPT-Red direct/indirect prompt-injection robustness (99.99%/99.79%), and alignment evaluations covering Auto-review circumvention, warning-bypass behavior, and blocker/search-tool deception, alongside HealthBench, MentalHealthBench and hallucination benchmarks.
OpenAI's system card for ChatGPT Images 2.5, covering the GPT-Image-2.5-Sunburst and GPT-Image-2.5-Flare models, details a multi-layer image safety stack (upstream LLM policy refusals, a multimodal safety reasoning model for input/output blocking) built to counter heightened deepfake realism risks. It reports adversarial-prompt evaluation results against ChatGPT Images 2.0, Preparedness Framework assessments for biological and cyber capability (image-modality adaptations of existing LLM evals, neither model crossing the "High" threshold but biological-risk mitigations still applied precautionarily), and expanded provenance tooling via C2PA metadata and Google DeepMind's SynthID watermarking.
