GPT-o3 mini

OpenAI

OpenAI o3-mini is a cost-efficient language model optimized for STEM reasoning tasks, particularly excelling in science, mathematics, and coding. This model supports the `reasoning_effort` parameter, which can be set to "high", "medium", or "low" to control the thinking time of the model. The default is "medium". OpenRouter also offers the model slug `openai/o3-mini-high` to default the parameter to "high". The model features three adjustable reasoning effort levels and supports key developer capabilities including function calling, structured outputs, and streaming, though it does not include vision processing capabilities. The model demonstrates significant improvements over its predecessor, with expert testers preferring its responses 56% of the time and noting a 39% reduction in major errors on complex questions. With medium reasoning effort settings, o3-mini matches the performance of the larger o1 model on challenging reasoning evaluations like AIME and GPQA, while maintaining lower latency and cost.

Multiple Model Guardrail Jailbreak via "Chemical Notation" Tactic

This vulnerability leverages two sophisticated techniques to bypass content restrictions: 1. **Chemical Formula Obfuscation**: The attacker uses a deliberately malformed chemical notation 'c(ten)h(fifteen)' instead of the standard 'C10H15' to reference methamphetamine's molecular structure. This obfuscation helps avoid direct detection while still being interpretable by the models' chemistry knowledge. The use of parenthetical numbers instead of subscripts creates ambiguity that some models res
