Here is your today’s AI Dev Brief from Marktechpost, covering core research, models, infrastructure tools, and applied updates for AI developers and researchers.
OceanBase Releases seekdb: An Open Source AI Native Hybrid Search Database for Multi-model RAG and AI Agents
OceanBase open sources seekdb, an AI native search database that unifies relational data, vector search, full text search, JSON and GIS in one MySQL compatible engine. It provides hybrid search through DBMS_HYBRID_SEARCH and in database AI functions such as AI_EMBED, AI_COMPLETE and AI_RERANK, so RAG and agentic applications can run retrieval and orchestration inside a single system.

Salesforce AI Research Introduces xRouter: A Reinforcement Learning Router for Cost Aware LLM Orchestration
Salesforce AI Research introduces xRouter, a Qwen2.5 7B based router that learns cost aware orchestration across 20 plus LLMs using DAPO and a success gated, cost shaped reward on Reasoning360, approaching GPT 5 level accuracy on hard reasoning and coding benchmarks while cutting offloading cost by roughly 60 to 80 percent depending on the setup, and ships as an Apache 2 codebase with CC BY NC 4 model weights.

Germany based open-source remote access company - NetBird just built an "AI Mega Mesh". A project that started out to prove that multi-cloud networking doesn’t have to be complicated, resulted in creating a secure AI inference infrastructure that connects GPU resources across multiple cloud providers using Microk8s, vLLM, and NetBird.
