- 4InfoQ·9/17/2026framework_updateAI Agents as an Internal Developer Platform
The article describes how AI agents are being used as an internal developer platform by combining semantic search with context from tools such as Git, Slack, and Jira. It also highlights the need for guardrails and observability through logs, metrics, and traces to control and understand agent behavior.
- 5The New Stack·9/5/2026researchBuilding Trust in Agentic RAG with Evidence Trails
The article argues that agentic RAG systems need structured evidence trails because agents can rewrite queries, choose tools, and make multiple retrieval decisions before answering. It recommends logging queries, sources, filters, scores, rejected results, and reasons so users can see citations and operators can audit how an answer was produced.
- 4InfoQ·9/2/2026researchBeyond Prompting: Context Engineering for Production AI
Ricardo Ferreira outlines practical context-engineering patterns for building production-grade AI applications beyond basic prompt design. He focuses on managing long- and short-term memory, reducing token usage with summarization, limiting context drift with reranking and semantic caching, and keeping API costs and latency under control.
- 7Hacker News·8/10/2026researchA critique of Google Search's decline and what may replace it
The article argues that Google Search is becoming less useful as results are increasingly shaped by ads, SEO manipulation, and AI-generated content. It suggests that the next phase of search may be more fragmented and potentially worse for users before any meaningful improvement emerges.
- 3Hacker News·7/28/2026product_launchWhy writers should keep their own website instead of relying on Substack
The article argues that writers should treat Substack as a distribution channel rather than their primary online home. It warns that depending on a platform for hosting, audience, and discoverability creates long-term risk if policies or business terms change. The piece recommends publishing on an owned website first and syndicating content elsewhere using the POSSE approach.
- 5The New Stack·7/16/2026researchWhy Smarter AI Caching Can Slow Systems Down
The article explains how exact-match caching with Redis helped early AI workloads but struggled once traffic and language variation increased. It then describes semantic caching with vector databases as a promising alternative, while noting that it can introduce higher latency, false matches, and operational complexity in production.
- 6The New Stack·7/10/2026researchRetrieval quality becomes the key challenge in AI agent design
The article argues that many AI agent failures are actually retrieval and context-building problems rather than generation problems. It highlights the need for better ranking, tracing, and evaluation in retrieval pipelines, especially when agents search across chat histories, documents, code, and other complex sources.
- 6InfoQ·7/7/2026product_launchHubSpot Scales Semantic Search to 20 Billion Vectors
HubSpot says its semantic search system has grown from a proof of concept into an internal platform used by more than 38 teams and now stores over 20 billion vectors. The service supports agents, retrieval-augmented generation (RAG), and contact deduplication, with retrieval quality and latency becoming more critical as agent usage increases.
- 5The New Stack·7/4/2026researchCheaper Models Alone Won’t Fix AI Token Costs
The article argues that the main cost problem in agentic AI is not just model price, but excessive token consumption across agent workflows. It highlights three approaches to lower spend: compressing context, routing simpler tasks to cheaper models, and using semantic caching to avoid repeating similar reasoning.
- 6Cloudflare Blog·7/1/2026product_launchCloudflare launches Attribution Business Insights for crawler traffic analysis
Cloudflare announced Attribution Business Insights, a new dashboard aimed at helping website owners distinguish between beneficial traffic and AI crawler activity that consumes resources without sending meaningful referrals. The company says the tool is designed for publishers and business decision-makers to better understand crawl-to-referral ratios and manage access to their content.
- 3OpenAI Blog·4/10/2026framework_updateUsing ChatGPT for Research
OpenAI explains how to use ChatGPT for research tasks with search and deep research features. The guide focuses on finding current information, evaluating sources, and producing structured insights.
