DeepSeek: Reverse Engineering an AI Assistant by Interviewing Itself
DeepSeek conducted a self‑interview to expose how its AI assistant processes prompts and generates responses. The analysis details the model’s architecture, including Mixture of Experts and Multi‑head Latent Attention, as well as its handling of context windows, tool calling, and memory. It also highlights limitations such as hallucinations, false confidence, and the challenges of introspection into model weights.
- ▪The self‑interview reveals that DeepSeek’s model uses a Mixture of Experts (MoE) combined with Multi‑head Latent Attention (MLA) to manage large context windows.
- ▪The model generates text token by token and can invoke external tools or retrieval‑augmented generation when enabled.
- ▪Introspection into the model’s internal weights is limited, leading to gaps between the model’s explanations and publicly documented behavior.
- ▪The analysis identifies hallucinations and over‑confidence as notable failure modes that affect reliability.
- ▪Safety mechanisms, including RLHF‑based alignment, shape the assistant’s personality and response style.
