Group: Advanced (bridge group) | Previous group exit: run long-term with release gates and versioning discipline | This group exit: know which engineering decision each frontier topic affects, and when to jump to Learn LLM
1. Overview
BLUF: none of these four topics ask you to master derivations; they ask for positional sense — they decide which model you pick, what latency structure to expect, why some outputs "think" for a long time. Every page is a bridge card: what problem it solves / which decision it affects / when to jump to Learn LLM.
| Card | One-line positioning | Mostly affects |
|---|---|---|
| Interpretability | Why the model produced this output | Debugging expectations, compliance narratives |
| Reasoning · test-time compute | "Thinking longer" is a performance axis | Latency structure, billing, stop conditions |
| MoE / frontier architectures | Sparsity and long-context architectures | Model choice and cost curves |
| Multimodal | Cross-modal inputs and outputs | Ingest pipeline and product shape |
Admission rule: this group only accepts bridge cards to Learn LLM's deep end, each with an explicit engineering decision impact; pure research content stays out, so the group cannot decay into a catch-all.
2. Usage
Unsure whether a frontier term matters to you → find a row above, read the card (each ≤130 lines), then decide whether to descend into Learn LLM. A real-world vision case pairs with the multimodal card (zh-only: /zh/tech/09-advanced/multimodal-vision-case (zh)).
3. Principles
This group carries no derivation body; Learn LLM is the canonical owner. Any mechanism name inside a card gets one positioning sentence, nothing more.
4. Development
"Development" here means the decision-impact table: each card lists what you change when the mechanism shifts (model choice / budget / stop conditions / data pipeline).
5. Resource Library
Each card's library lists primary sources (arXiv IDs, official statements) and the Learn LLM chapter direction; the evidence-level legend lives in Site boundaries.
