Anthropic open-sourced 12 financial-industry Agents and 11 MCP connectors. The real takeaway isn't the Agents themselves but the layered design of 'one prompt, two runtimes' and 'pure-file extensibility.'
Local Deep Research is a privacy-first deep research agent built on LangChain + LangGraph, integrating 20+ search engines and 30+ research strategies. Its flagship langgraph_agent_strategy takes the LLM-autonomous tool-calling approach, offering a fundamentally different paradigm from fixed-pipeline RAG graphs.
DeerFlow is ByteDance's open-source Super Agent Harness built on Python 3.12 + LangGraph. It orchestrates long-running tasks through sandboxes, long-term memory, sub-agents, skills, and a messaging gateway. It hit #1 on GitHub Trending in February 2026, now surpassing 63,000 stars, with support for Telegram/Slack/Feishu, Claude Code integration, and multiple search backends.
Agentic Engineering isn't about making AI write code faster — it's about making software move through the entire delivery pipeline faster, by using multi-agent collaboration to compress cross-team coordination friction.
Sorted by GitHub Stars, a survey of 15 mainstream AI Agent frameworks in 2026 — their positioning, key features, and ideal use cases. Not a ranking — it's a map.
LangGraph models LLM workflows as directed graphs, solving the pain points of multi-turn iteration, conditional branching, and parallel execution that are difficult to handle with linear pipelines.
A dynamically composable RAG pipeline built on Cloudflare Workers AI (gemma-3-12b-it + bge-m3): 14 base steps + 6 LangGraph-specific nodes, with three strategy graphs (Baseline / Agentic / Plan-Execute) selected at runtime.
