AI Response
Machine learning is a way for computers to learn patterns from data — instead of being explicitly programmed for every task, the system improves by exposure to examples.

What is Generative AI?

A new class of artificial intelligence that doesn't just analyze or predict — it generatesGenerative — capable of producing new content (text, images, audio, code) rather than only classifying or predicting from existing data. entirely new content from learned patterns.

Artificial Intelligence

The broad field of building systems that can perform tasks normally requiring human intelligence — reasoning, perception, language understanding.

Generative AI

A branch of AI focused on creating models that produce new content — text, images, audio, video, or code — by learning distributions from training data.

"Generative" Meaning

Producing something new rather than classifying existing input. The model creates output that did not exist verbatim in its training data.

Inside Large Language Models

LLMs are the most impactful GenAI models today. Understand their types, deployment models, and the Transformer architecture that powers them.

What is an LLM?

A Large Language Model (LLM) is a neural network trained on massive text corpora to predict the next token in a sequence. Through this simple objective, models learn grammar, facts, reasoning abilities, and coding skills.

Parameters: Billions of learned weights (e.g., 70B)
Pre-training: Self-supervised learning on internet text
Fine-tuning: Alignment via RLHF or instruction tuning
Emergent abilities: Capabilities appearing only at scale

Language Modeling

The core task: assign probabilities to sequences of text. Modern LLMs do this autoregressively — predicting one token at a time, conditioned on all previous tokens.

# Autoregressive generation
Input: "The capital of France is"
Predict: " Paris" (p=0.98)
Input: "The capital of France is Paris"
Predict: "." (p=0.85)
Input: "The capital of France is Paris."
Predict: "" (p=0.92)

Types of LLMs by Architecture

Open Source vs Proprietary LLMs

Proprietary
Closed weights, API-only
Examples: GPT-4, Claude, Gemini
Best performance: State-of-the-art reasoning and capabilities.
No infra needed: Just call the API.
Polished UX: Polished tools and ecosystems.
Vendor lock-in: Dependent on provider's roadmap and pricing.
Data privacy: Data leaves your infrastructure.
Cost at scale: Per-token pricing adds up fast.
Open Source
Open weights, self-hostable
Examples: Llama 3, Mistral, Qwen
Full control: Modify, fine-tune, and inspect weights.
Data privacy: Run entirely on your own infrastructure.
Lower cost at scale: No per-token API fees.
Requires infra: Need GPUs and MLOps expertise.
Capability gap: Generally trail proprietary models.
Maintenance: Self-hosted security and scaling.

Transformer Architecture & Self-Attention

The engine of modern LLMs. Hover over any word to see what it "attends" to.

How Transformers Work

1. Embeddings: Convert tokens into high-dimensional vectors capturing meaning.

2. Positional Encoding: Add order information since attention is permutation-invariant.

3. Multi-Head Attention: Each token computes relationships with every other token. Multiple "heads" capture different relationship types (syntax, coreference, etc.).

4. Feed-Forward Network: Processes the attention output non-linearly.

5. Residual Connections: Information skips around layers to prevent gradient loss.
