LangChain

NVIDIA published NemoClaw, a set of open blueprints that assemble a tuned agent harness, Nemotron models, NeMo optimization tools and the OpenShell secure runtime. The blueprints currently support OpenClaw, Hermes Agent and LangChain Deep Agents. LangChain says its tuned Deep Agents harness brings Nemotron 3 Ultra to near-frontier performance at approximately 10x lower cost per run.

AWS has launched LangChain Deep Agents, an orchestration framework that spawns isolated subagents using Amazon Bedrock AgentCore infrastructure. AgentCore provides dedicated browser MicroVMs running Chromium via Playwright and full Python environments with pre-installed data science libraries, enabling parallel agent execution without context window competition.
