1. Kimi K3 Architecture Deep Dive: 2.78T Hybrid MoE Attention Innovation
Sebastian Raschka breaks down Kimi K3's architecture layer by layer, with Grouped Latent Attention and sparse expert routing keeping inference costs near small-model levels despite 2.78T parameters. Unlike your Agent Plan workflow, this is model-level innovation — understanding sparse attention design helps you decide what to run locally vs. via API.

2. Is AI reasoning right for the wrong reasons?
Quanta Magazine covers new research showing CoT chains sometimes represent genuine reasoning, but in other cases are pseudo-reasoning that happens to land on the right answer — a crucial caveat for agent reliability evaluation. For AI quality control: a correct output ≠ trustworthy reasoning.

3. 93 lines of formal spec vs. 1000+ lines of AI-written code
verified-3d-mesh-intersection demonstrates a contrarian quality-control path: instead of line-by-line review of AI-generated code, constrain correctness with formally verified specs. Same philosophy as adding AI Code Review to your pipeline — just moving the review target from code up to the specification.

4. Show HN: How to build and self-host a code review agent
A hands-on tutorial covering model selection, CI integration, and context-window tradeoffs for a self-hosted code review agent. A solid starting point if you want to move AI Code Review from concept to implementation.

🛠️ Tools & Tips
1. Everyone is building LLM routers, we deprecated ours
manifest.build explains why they killed their own LLM router: for most workloads the routing layer's complexity isn't worth it — just pick one good model. Contrarian and worth reading.

2. Run the full 2.78T Kimi K3 on 29GB RAM via NVMe streaming
waste is a dependency-free C inference engine that streams activated weights directly from NVMe, bypassing RAM limits — roughly 0.50 tok/s in practice. For cheaply playing with very large models.
