The post includes a public repository with code assets.
Orca Security partnered with AWS to build Discovery AI on Amazon Bedrock, translating natural language questions into validated Sonar queries across 900+ cloud infrastructure and application models. The architecture combines example retrieval and reranking, relevant schema selection, agentic generation, and validation, with domain experts continuously updating the example bank. Compared with its initial baseline, Orca reports 90 percent lower costs, 93 percent fewer input tokens, and 75 percent lower latency, with response times falling from approximately 60 seconds to 15 seconds.
Why it matters: The architecture offers a transferable approach to querying large schemas by retrieving validated examples, selecting relevant schema fragments, and feeding validation errors back into generation.
Amazon Quick and Amazon Bedrock Knowledge Bases have added real-time ACL checks at query time, alongside pre-retrieval ACL filtering. They verify permissions directly with authoritative data sources, avoiding reliance on ACL data that may be stale or incorrectly mapped.
Qlik built Qlik Answers on Amazon Bedrock, providing traceable enterprise question answering to more than 40,000 customers worldwide. Since becoming generally available in February 2026, its Discovery Agent has found more than 100,000 anomalies and outliers for customers.
Google DeepMind released EmbeddingGemma 2, a 740M-parameter open model based on the Gemma 4 architecture and licensed under Apache 2.0. It maps text, images, audio, and video into a shared embedding space.
Why it matters: EmbeddingGemma 2 maps text, images, audio, and video into one embedding space and reports concrete on-device memory and vector truncation figures, helping assess local multimodal retrieval.
Amazon Bedrock Managed Knowledge Base introduced agentic retrieval. Its AgenticRetrieveStream API breaks multi-part questions into subqueries, repeatedly checks whether the evidence is sufficient, and searches again when needed, replacing the Retrieve API's single vector search.
Ai2 open-sourced AstaBrief 8B, a model that turns research questions and retrieved literature excerpts into reports with citations. It was trained from Qwen3-8B using SFT and DPO and is now available as Asta's Fast mode.
Why it matters: The source describes AstaBrief's training-data construction and citation-filtering details, which can be adapted to deploy other long-form generation models.
Amazon SageMaker AI can use multi-turn reinforcement learning (MTRL) to fine-tune search agents. It models agent tasks as sequences of multi-turn decisions, generates data through multiple rollouts, and optimizes the model with policy gradients.
AWS proposed the Adjudicated Query design pattern, in which business users ask compliance questions in the Amazon Quick chat interface while a deterministic rules engine makes the actual decision. An integrity receipt ensures that the sum of compliant, noncompliant, ambiguous, and unreadable records equals the total scanned, preventing records from being silently skipped. The pattern applies to high-risk cases such as lease compliance, sanctions screening, and insurance claims.
Amazon Bedrock Knowledge Bases added the AgenticRetrieveStream API, which breaks claims questions into subqueries, retrieves information over multiple rounds, and returns cited answers.
To address aggregate questions spanning hundreds of contracts that semantic RAG search cannot answer, this approach uses structured extraction instead. An extraction agent powered by Claude Sonnet models pulls eight key fields from each PDF and attaches confidence scores; a lightweight Claude Haiku model independently checks the results, while Amazon Textract uses computer vision to resolve disagreements over signature detection.
Condé Nast and AWS's Generative AI Innovation Center (GenAIIC) built a multimodal video search solution using Amazon Bedrock and Amazon OpenSearch Service. It uses TwelveLabs Marengo embeddings to jointly encode visuals, audio, and transcripts, cutting a single content search from 250 minutes to under two minutes.
NarrateAI uses five techniques on Amazon Bedrock to achieve about 99% numerical accuracy while supporting real-time streaming responses: adaptive pipeline orchestration, cross-account multi-model failover, real-time streaming evaluation, a composite evaluation framework, and data-accuracy validation. Each addresses failure modes such as hallucinated metrics, API throttling, validation delays, and subjective language. Built on Amazon Bedrock AgentCore, the solution serves more than 4,000 AWS executives.
Datacor embedded Amazon Quick Sight in its TrackAbout solution, giving industrial gas and welding distributors interactive dashboards and natural-language search so business users can query rental data without filing IT tickets. TrackAbout customers manage more than 725,000 invoices and 27.5 million assets each month. The new solution refreshes SPICE datasets on a schedule through a cross-cloud data pipeline and supports analyses of fleet utilization, billing anomalies, and revenue recovery.
The latest GitHub Podcast examines five popular AI claims. AI-generated code still needs to be read and owned, with review effort scaled to risk; Skills and MCP address different needs, with Skills packaging team expertise and MCP standardizing connections to tools and data; and RAG is not dead, since it can coexist with agents, Skills, and MCP in one workflow. The episode also discusses judging AI fluency in hiring and how fine-tuning needs can signal codebase maintainability problems.
Hugging Face has introduced the NeoMME family of multimodal multilingual encoders in 260M and 800M sizes. A single bidirectional Transformer directly processes text tokens and raw image patches, without a separate vision tower or causal language model.
