Production RAG teams face a core tradeoff between controlled semantic chunking and simpler API-managed options.

• Semantic chunking preserves related...

Enterprise AI fails when conversations stop at model selection. Production success requires four infrastructure layers: compute, model storage,...

RAG pipelines must treat every retrieved chunk as untrusted input rather than trusted context, since it carries the same authority as the system...

• Chart JSON extraction via ai_parse_document lifts agent accuracy on visual questions from incorrect (17) to correct (18), outperforming frontier...

An agentic RAG pipeline routes between internal vector search and real-time web retrieval when private knowledge proves insufficient, then evaluates evidence for cited answers.

The cheapest production token is irrelevant context never placed in the prompt. Selective retrieval—embed, hybrid search with $rankFusion, rerank, then send only the top results—cuts input tokens, latency, and dilution while improving answer quality.

• Multi-hop retrieval chains sequential searches for questions spanning disconnected documents, using DSPy modules, Baleen condensation, and Self-RAG...

Nvidia's Vera CPU targets the real limiter in agentic systems: orchestration overhead that leaves GPUs idle between tool calls, context assembly, and...

Practical agent memory systems are shipping fast, yet Meta's re-evaluation questions whether scale alone drives gains.

A single prompt can embed attacker-controlled instructions that persist in AI agent memory and steer future responses on related topics, unlike...

• Semantic search now powers meaning-based retrieval across Google Drive, Gong, and Linear via the pre-indexed Context Store, cutting tokens up to...

AutoSaddler treats the agent harness as code and learns to patch it offline from failures, replacing the hand-tuned approach still dominant in agent systems. The Microsoft paper presents a closed-loop optimizer for this critical infrastructure layer.

Apodex 1.1 introduces a framework for scaling agentic intelligence to handle complex work. The paper is now available for examination.

• Corpus design determines success: flat vector stores fail on enterprise folders by mixing incompatible documents, unlike expert handlers who first...

Three developments highlight practical gains in filtered search, index tuning, and embeddings:

• BigFANN uses hybrid graph-IVF indices and join-free...

The prior Azure deployment used an orchestrator to route between evidence and structured knowledge layers. It delivered reliable contradiction...

Two new courses trace the evolution of production-grade AI agents from foundational architecture to complex, reliable deployments.

Four architectures reveal distinct trade-offs in structure, sharing, and temporal handling.
