# DeepSeek-V3 Model: Theory, Config, and Rotary Positional Embeddings

**[PyImageSearch](https://daily.dev/sources/pyimagesearch)** · 18 min read · 1 upvotes · 0 comments

## Summary

A hands-on tutorial series introducing DeepSeek-V3's architecture by building it from scratch in PyTorch. Covers the four core innovations: Multihead Latent Attention (MLA) for KV cache compression, Mixture of Experts (MoE) for efficient scaling, Multi-Token Prediction (MTP) for richer training signals, and Rotary Positional Embeddings (RoPE) for better positional encoding. This first lesson implements the model configuration dataclass and the RoPE/RMSNorm modules, with a small educational model trained on TinyStories as the target.
