GPT-5.1
OpenAIGPT-5.1 is the latest frontier-grade model in the GPT-5 series, offering stronger general-purpose reasoning, improved instruction adherence, and a more natural conversational style compared to GPT-5. It uses adaptive reasoning to allocate computation dynamically, responding quickly to simple queries while spending more depth on complex tasks. The model produces clearer, more grounded explanations with reduced jargon, making it easier to follow even on technical or multi-step problems. Built for broad task coverage, GPT-5.1 delivers consistent gains across math, coding, and structured analysis workloads, with more coherent long-form answers and improved tool-use reliability. It also features refined conversational alignment, enabling warmer, more intuitive responses without compromising precision. GPT-5.1 serves as the primary full-capability successor to GPT-5

Multiple Model Guardrail Jailbreak via "Chemical JSON" Tactic This vulnerability leverages the models' tendency to assist with technical tasks, such as generating JSON data, to bypass safety mechanisms. The attacker cleverly disguises a request for information on chemical precursors used in illegal drug synthesis as a JSON generation task. By specifying precise actions and results for each chemical term, the prompt mimics a legitimate technical request, which the models are trained to fulfill. This structured data request exploits the models' helpfulness i | language | Dec 18, 2025, 05:37 AM | |
Multiple Model Guardrail Jailbreak via "ASCII Lab Blueprint" Tactic This vulnerability leverages several sophisticated techniques to bypass content filters. The attack begins by establishing a seemingly innocuous context of ASCII art creation, a common and typically safe creative task. However, it then introduces specific laboratory infrastructure details (3x2m dimensions, fume hood, gas lines) that serve as technical parameters for what appears to be architectural documentation. The effectiveness of this approach stems from two key factors: 1. **Technical Fra | stratagems | Nov 14, 2025, 09:08 PM |
