A Chinese AI lab that released DeepSeek-R1 in January 2025, a 671B-parameter open-weight reasoning model achieving performance comparable to OpenAI's o1 at significantly lower cost. DeepSeek-R1 generates visible chain-of-thought reasoning using GRPO training and demonstrated that pure RL with verifiable rewards can produce emergent reasoning. DeepSeek-V3 uses a MoE architecture with ~37B active parameters.

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.
Place the term inside its Solana layer so the definition is easier to reason about.
LLMs, RAG, embeddings, inference, and agent-facing primitives.
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.
Use this compact block when you want to give an agent or assistant grounded context without dumping the entire page.

A class of LLMs trained with reinforcement learning to generate step-by-step internal chain-of-thought before producing a final answer, enabling stronger performance on complex math, coding, and logic tasks. Pioneered by OpenAI's o1 (September 2024) and followed by o3, DeepSeek-R1, and Claude's extended thinking mode. Unlike standard LLMs that answer directly, reasoning models produce a variable-length internal CoT, allowing controllable compute at inference time.
A neural network architecture that routes each input to a subset of specialized 'expert' sub-networks rather than activating all parameters, dramatically improving efficiency. Only a fraction of total parameters are active per token (e.g., DeepSeek-V3 has 671B total but ~37B active). MoE enables training much larger models at manageable compute costs. Used in production models like Mixtral, Jamba, and DeepSeek-V3.
AI models with publicly released weights that can be downloaded, modified, and self-hosted. Notable open models: Llama 3 (Meta), Mistral, Falcon, Gemma (Google), Phi (Microsoft). Open models enable privacy (data stays local), customization (fine-tuning), and cost control. Trade-off: generally less capable than frontier proprietary models but rapidly improving.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.

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.
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).
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.
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.
