Base model weights

The learned parameters (numerical tensors) within a neural-network or large-language-model (LLM) that are optimized during the Pre-training process. These weights encode the patterns, linguistic structures, and factual information captured from the training corpus.

Core Principles

Knowledge Storage: The weights act as the foundational repository of learned information within the Model Architecture.
Inference Engine: During inference, input vectors are transformed through matrix multiplications with these weights to produce outputs.
Adaptability: Base weights serve as the starting point for fine-tuning, instruction-tuning, and Parameter-Efficient Fine-Tuning (PEFT) techniques.
Open-Source Accessibility: The availability of high-quality weights, such as those in the DeepSeek V4 suite, drives innovation in the open-source ecosystem.

DeepSeek V4 represents a significant advancement in the release of high-performance, open-source model weights designed for computational efficiency and scale.
