Linear Attention at Frontier Scale: Kimi K3's KDA Claim, Fact-Checked
Kimi K3 runs linear attention in 3 of 4 layers and claims it beats full attention. What the 48B evidence shows, and what stays unverified at 2.8T scale.
Agent Memory Beyond RAG: Why Your Agent Needs a Write Path, Not a Retriever
Agent memory is not RAG: it needs a write path, not just retrieval. Memory types, temporal knowledge graphs, forgetting by design, and why chat logs fall short.

LLM Inference in Production
A practical route through the serving stack. Start with the map of where inference cost and latency actually come from, take the quantization lever apart, speed up decoding with speculative drafts and measure it yourself, confront what long context really delivers, and finish at the 2026 state of the art. Every step names its tradeoffs.
Understanding Modern LLM Architectures
A guided journey from transformer fundamentals to the cutting edge of LLM engineering. You will build an intuition for how modern language models are designed, scaled, optimized, and deployed, by covering attention mechanisms, Mixture of Experts, architectural innovations like DeepSeek's MLA, reasoning capabilities, inference optimization, and the open-source ecosystem reshaping AI.
