Transformer
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.
Why it matters
The transformer is the breakthrough that made today's AI boom possible. Almost every well-known model, from ChatGPT to translation and coding tools, is built on it. Its key trick, processing an entire sequence at once rather than word by word, let researchers train on massive datasets efficiently. Knowing the name helps you understand why so many different AI products share similar strengths and quirks under the hood.
In practice
When you type a sentence into a chatbot, the transformer looks at every word simultaneously and weighs how they relate, so it understands that "bank" means a riverbank or a financial one based on surrounding words. This parallel processing is why modern models feel fluent. You do not need to configure anything; the point is simply recognizing that this one architecture powers most tools you'll encounter.

AI Dubbing
Automated translation and re-voicing of audio/video content into other languages while preserving the original speaker's voice characteristics, timing, and emotional delivery.
AI Orchestration
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.
API (Application Programming Interface)
A way for software applications to communicate with each other. AI APIs let developers integrate AI capabilities into their own applications programmatically.
Attention Mechanism
A technique that allows AI models to focus on the most relevant parts of input data when generating output. In language models, attention determines which words in a sentence are most important for understanding each other word.
Diffusion Model
A type of generative AI that creates images by gradually removing noise from a random starting point. Powers tools like Stable Diffusion, DALL-E, and Midjourney. Works by learning the reverse of a noise-adding process.
Distillation
A technique where a smaller 'student' model learns to replicate the behavior of a larger 'teacher' model. Produces compact models that retain most of the teacher's capability while being faster, cheaper, and deployable on smaller devices.
