Bias (in AI)When an AI system produces results that systematically favor or disadvantage certain groups, often because of skewed training data.Bio-AI hybridSpotitEarly's term for a platform where a biological sensor sits at the front of the pipeline and machine learning handles interpretation and verification.Brand Knowledge GraphEmberos's proprietary mapping of how a brand's entities, products, narratives, and digital assets relate to each other across the internet, enabling predictive visibility modeling.BYO-LLM (Bring Your Own LLM)An architecture pattern where enterprise customers plug their own AI vendor API key into a product so data flows through their existing legal agreements rather than a vendor's.Calibrated ProbabilityA probability estimate that accurately reflects the true likelihood of an outcome over many predictions: if you say something has a 70% chance, it should materialize roughly 70% of the time. Calibration is a distinct measure from raw accuracy - a model can win most of its bets while being badly miscalibrated (e.g., stating 95% confidence on events that only happen 60% of the time). LightningRod measured its forecasting model on Polymarket using calibration as a primary metric, not just profit or win rate. Ben Turtle uses Polymarket bets as a forcing function for calibration training: putting money down on a prediction and seeing the outcome is the fastest way to build an accurate internal probability estimator.Capability BoundaryThe outer limit of what a person or team can produce at a given level of staffing and skill. AI extends this boundary — enabling smaller teams to produce work previously requiring larger ones. Section operates with 32 people doing the work of 45. For founders, this changes the build vs. hire calculation: always audit your AI-extended capability before adding headcount.Capability overhangThe gap between what frontier models can already do and what they're actually being used for.ChatbotA program that holds a conversation with people through text or voice.
