Transformer

The neural network architecture underlying modern LLMs, introduced in 'Attention Is All You Need' (2017). Transformers use self-attention mechanisms to process input sequences in parallel (unlike recurrent networks). Key components: multi-head attention, positional encoding, feedforward layers, and layer normalization. Variants include encoder-only (BERT), decoder-only (GPT), and encoder-decoder (T5).

Mental model

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.

Think of it as a piece of the context or inference stack behind agentic and LLM-powered Solana products.

Technical context

Place the term inside its Solana layer so the definition is easier to reason about.

LLMs, RAG, embeddings, inference, and agent-facing primitives.

Why builders care

Turn the term from vocabulary into something operational for product and engineering work.

This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

These branches show which concepts this term touches directly and what sits one layer beyond them.

Branch

LLM (Large Language Model)

A neural network trained on vast text corpora to understand and generate human language. LLMs (GPT-4, Claude, Llama, Gemini) use transformer architectures with billions of parameters. They power chatbots, code generation, summarization, and reasoning tasks. In blockchain development, LLMs assist with smart contract writing, audit review, documentation, and code explanation.

Branch

Attention Mechanism

A neural network component that allows models to weigh the relevance of different parts of the input when producing output. Self-attention computes query-key-value dot products across all positions, enabling each token to 'attend' to every other token. Multi-head attention runs multiple attention functions in parallel. Attention is O(n²) in sequence length, driving context window research.

AI / ML

Vector Database

A database optimized for storing and querying high-dimensional vector embeddings using similarity search (cosine distance, dot product, Euclidean distance). Examples: Pinecone, Weaviate, Qdrant, ChromaDB, pgvector. Vector databases power RAG systems by quickly finding the most relevant documents for a given query embedding. Essential for AI-powered developer tools and documentation search.

AI / ML

Training (ML)

The process of optimizing a model's parameters by exposing it to data and adjusting weights to minimize a loss function. Pre-training on large datasets creates foundation models. Training LLMs requires massive compute (thousands of GPUs, weeks/months). Training data quality, diversity, and size directly impact model capabilities. Distinguished from fine-tuning (smaller scale, specific domain).

AI / MLtokenomics

Tokenomics

The economic design of a cryptocurrency token: supply schedule, distribution, utility, incentive mechanisms, and value accrual. Key parameters: total/circulating supply, inflation/deflation, vesting schedules, staking rewards, fee burning, and governance rights. Good tokenomics aligns incentives between users, developers, and token holders. AI tools increasingly help analyze tokenomics models.

Foundation Model

A large AI model trained on broad data that can be adapted for many downstream tasks. Foundation models (GPT-4, Claude, Llama 3, Gemini) are pre-trained on internet-scale text/code and can be fine-tuned, prompted, or used via APIs for specific applications. The term emphasizes that one base model serves as the foundation for diverse use cases rather than training task-specific models.

AI / ML

Prompt Engineering

The practice of crafting input text (prompts) to guide LLM behavior and output quality. Techniques include: zero-shot (direct instruction), few-shot (providing examples), chain-of-thought (step-by-step reasoning), system prompts (setting context/persona), and structured output formatting. Effective prompts are specific, provide context, and include constraints. Critical for AI-assisted blockchain development.
