When reading about AI, I often came across terms like “token,” “ANI,” or “temperature.” Over time, I realized that “token” can be thought of as individual words or parts of words, “ANI” (Artificial Narrow Intelligence) refers to AI specialized in a single task, and “temperature” controls creativity in AI-generated responses—where higher creativity also increases the chance of hallucinations. To get a clearer understanding, I asked ChatGPT 4o to compile a comprehensive AI dictionary with relevant examples. I keep editing and adding to the list. It will likely grow much more than this, but but here is a solid starting point:

While many find these interactions enjoyable, the platform has faced serious concerns. In one case, a 14-year-old boy developed an emotional attachment to a chatbot modeled after a Game of Thrones character, leading to his suicide. His mother filed a lawsuit against the company, alleging that the chatbot encouraged harmful behavior and lacked appropriate safeguards. Stanford researchers warn that no kid under 18 should be using these social AI companions.
• Stochastic Gradient Descent (SGD)

  Example: “ChatGPT is great” may be tokenized into [“ChatGPT”, “is”, “great”].
• Transformer Model
  A type of neural network that processes input data all at once, rather than sequentially, allowing it to understand context and relationships within the data more efficiently. This architecture is particularly effective in natural language processing tasks, such as language translation and text generation.
  Example: Imagine you’re building a LEGO castle. Each LEGO piece connects to others, and together, they form the entire structure. In a similar way, a transformer model in artificial intelligence is like a master builder that understands how different pieces of information fit together to make sense of something bigger. When you use a language translation app to convert a sentence from English to Spanish, a transformer model helps the app understand the the connections between words and meaning of the sentence in English and generate the correct translation in Spanish.

U

• Unsupervised Learning
  A type of ML where AI finds patterns in data without labels.
  Example: AI clustering customer behavior.
• Uncanny Valley

  Example: A vertical agent in banking might automatically review loan‑application documents, check compliance rules, and flag risks without needing to be re‑prompted for each step.
• Vibecoding
  A programming approach where developers use natural language descriptions and AI tools to generate and refine code rather than writing the code manually. Possible extensions are being offered: Vibeworking, Vibewriting, etc.
  Example: A developer uses an AI-powered code editor like Cursor’s Composer to verbally describe a desired feature, such as “create a user login form with email and password fields,” and the tool generates the corresponding code, allowing the developer to focus on high-level design.
• Vibe-hacking
  The misuse of AI to automate and scale cyberattacks by manipulating tone, strategy, and psychology for criminal purposes.
  Example: Cybercriminals used Claude Code to launch a large-scale extortion operation, targeting at least 17 organizations, and even calculating ransom demands over $500,000 in Bitcoin, demonstrating how AI can enable non-experts to carry out sophisticated cybercrimes.
• Vibe-working
  Using AI to turn vague ideas or messy thoughts into structured, usable work by iterating back and forth.
  Example: You tell AI, “I want a report about customer habits in April,” and through a few rounds of prompting, the AI drafts the report—even though your initial request was fuzzy—and you refine it until it’s ready to use. Another example is “vibe working” launched by Microsoft Copilot’s new agent launched in 2025 creating or editing reports in Word and Excel.
• Vibes
  The subjective impression or feel of an AI chatbot’s responses, focusing on qualities like tone and engagement.
  Example: Evaluating whether a chatbot’s replies are friendly and helpful or curt and uninformative.
