AI Glossary

Running two or more prompt variations against the same AI model to compare output quality. Data-driven prompt optimization that consistently outperforms intuition-based prompting.

AI systems that operate autonomously over extended tasks — planning, executing, and self-correcting without step-by-step human guidance. Unlike chatbots, agentic AI sets sub-goals, uses tools, and adapts its strategy based on intermediate results.

An autonomous AI system that can perceive its environment, make decisions, and take actions to achieve goals — like managing your email, scheduling meetings, or monitoring data.

The research challenge of ensuring AI systems pursue goals that are beneficial to humans. Misaligned AI could technically achieve its objective while causing unintended harm. Alignment research aims to make AI reliably helpful, harmless, and honest.

A tool that estimates whether a passage of text was generated by an AI model, by measuring statistical properties of the writing rather than by checking any record of its origin.

Stating that AI was used in producing a piece of work, where a policy, client or publisher requires it. Distinct from permission: some contexts allow AI use but require it to be declared.

Automated translation and re-voicing of audio/video content into other languages while preserving the original speaker's voice characteristics, timing, and emotional delivery.

Coordinating multiple AI models, tools, and data sources in a unified pipeline. An orchestration layer manages prompt routing, context passing, error handling, and output aggregation across different AI services.

The component that splits text into tokens (sub-word units) before feeding it to an AI model. Different models use different tokenizers — affecting how they count input length, handle multilingual text, and process code.

The ability of AI models to invoke external tools, APIs, or functions during a conversation. Enables AI to perform real actions — searching the web, querying databases, sending emails, or running calculations — not just generate text.

AI systems that identify harmful, offensive, or inappropriate content in text. Essential for content safety pipelines in professional and enterprise contexts.

The neural network architecture behind modern AI models like GPT and BERT. Uses self-attention mechanisms to process entire sequences in parallel, enabling much faster training than previous architectures. Nearly all large language models are transformer-based.
