📝 Guest Post: Local Agentic RAG with LangGraph and Llama 3*

New Post has been published on https://thedigitalinsider.com/guest-post-local-agentic-rag-with-langgraph-and-llama-3/

📝 Guest Post: Local Agentic RAG with LangGraph and Llama 3*

In this guest post, Stephen Batifol from Zilliz discusses how to build agents capable of tool-calling using LangGraph with Llama 3 and Milvus. Let’s dive in.

LLM agents use planning, memory, and tools to accomplish tasks. Here, we show how to build agents capable of tool-calling using LangGraph with Llama 3 and Milvus.

Agents can empower Llama 3 with important new capabilities. In particular, we will show how to give Llama 3 the ability to perform a web search, call custom user-defined functions

Tool-calling agents with LangGraph use two nodes: an LLM node decides which tool to invoke based on the user input. It outputs the tool name and tool arguments based on the input. The tool name and arguments are passed to a tool node, which calls the tool with the specified arguments and returns the result to the LLM.

Milvus Lite allows you to use Milvus locally without using Docker or Kubernetes. It will store the vectors you generate from the different websites we will navigate to. 

Introduction to Agentic RAG

Language models can’t take actions themselves—they just output text. Agents are systems that use LLMs as reasoning engines to determine which actions to take and the inputs to pass them. After executing actions, the results can be transmitted back into the LLM to determine whether more actions are needed or if it is okay to finish.

They can be used to perform actions such as Searching the web, browsing your emails, correcting RAG to add self-reflection or self-grading on retrieved documents, and many more.

Setting things up

LangGraph – An extension of Langchain aimed at building robust and stateful multi-actor applications with LLMs by modeling steps as edges and nodes in a graph.

Ollama & Llama 3 – With Ollama you can run open-source large language models locally, such as Llama 3. This allows you to work with these models on your own terms, without the need for constant internet connectivity or reliance on external servers. 

Milvus Lite – Local version of Milvus that can run on your laptop, Jupyter Notebook or Google Colab. Use this vector database we use to store and retrieve your data efficiently.

Using LangGraph and Milvus

We use LangGraph to build a custom local Llama 3-powered RAG agent that uses different approaches:

We implement each approach as a control flow in LangGraph:

Routing (Adaptive RAG) –  Allows the agent to intelligently route user queries to the most suitable retrieval method based on the question itself. The LLM node analyzes the query, and based on keywords or question structure, it can route it to specific retrieval nodes.

Example 1: Questions requiring factual answers might be routed to a document retrieval node searching a pre-indexed knowledge base (powered by Milvus).

Example 2: Open-ended, creative prompts might be directed to the LLM for generation tasks.

Fallback (Corrective RAG) – Ensures the agent has a backup plan if its initial retrieval methods fail to provide relevant results. Suppose the initial retrieval nodes (e.g., document retrieval from the knowledge base) don’t return satisfactory answers (based on relevance score or confidence thresholds). In that case, the agent falls back to a web search node.

The web search node can utilize external search APIs.

Self-correction (Self-RAG) – Enables the agent to identify and fix its own errors or misleading outputs. The LLM node generates an answer, and then it’s routed to another node for evaluation. This evaluation node can use various techniques:

Reflection: The agent can check its answer against the original query to see if it addresses all aspects.

Confidence Score Analysis: The LLM can assign a confidence score to its answer. If the score is below a certain threshold, the answer is routed back to the LLM for revision.

General ideas for Agents

Reflection – The self-correction mechanism is a form of reflection where the LangGraph agent reflects on its retrieval and generations. It loops information back for evaluation and allows the agent to exhibit a form of rudimentary reflection, improving its output quality over time.

Planning – The control flow laid out in the graph is a form of planning, the agent doesn’t just react to the query; it lays out a step-by-step process to retrieve or generate the best answer.

Tool use – The LangGraph agent’s control flow incorporates specific nodes for various tools. These can include retrieval nodes for the knowledge base (e.g., Milvus), demonstrating its ability to tap into a vast pool of information, and web search nodes for external information.

Examples of Agents

To showcase the capabilities of our LLM agents, let’s look into two key components: the Hallucination Grader and the Answer Grader. While the full code is available at the bottom of this post, these snippets will provide a better understanding of how these agents work within the LangChain framework.

Hallucination Grader

The Hallucination Grader tries to fix a common challenge with LLMs: hallucinations, where the model generates answers that sound plausible but lack factual grounding. This agent acts as a fact-checker, assessing if the LLM’s answer aligns with a provided set of documents retrieved from Milvus.

```

### Hallucination Grader 

# LLM

llm = ChatOllama(model=local_llm, format="json", temperature=0)

# Prompt

prompt = PromptTemplate(

    template="""You are a grader assessing whether 

    an answer is grounded in / supported by a set of facts. Give a binary score 'yes' or 'no' score to indicate 

    whether the answer is grounded in / supported by a set of facts. Provide the binary score as a JSON with a 

    single key 'score' and no preamble or explanation.

    Here are the facts:

    documents 

    Here is the answer: 

    generation

    """,

    input_variables=["generation", "documents"],

)

hallucination_grader = prompt | llm | JsonOutputParser()

hallucination_grader.invoke("documents": docs, "generation": generation)

```

Answer Grader

Following the Hallucination Grader, another agent steps in. This agent checks another crucial aspect: ensuring the LLM’s answer directly addresses the user’s original question. It utilizes the same LLM but with a different prompt, specifically designed to evaluate the answer’s relevance to the question.

```

def grade_generation_v_documents_and_question(state):

    """

    Determines whether the generation is grounded in the document and answers questions.

    Args:

        state (dict): The current graph state

    Returns:

        str: Decision for next node to call

    """

    print("---CHECK HALLUCINATIONS---")

    question = state["question"]

    documents = state["documents"]

    generation = state["generation"]

    score = hallucination_grader.invoke("documents": documents, "generation": generation)

    grade = score['score']

    # Check hallucination

    if grade == "yes":

        print("---DECISION: GENERATION IS GROUNDED IN DOCUMENTS---")

        # Check question-answering

        print("---GRADE GENERATION vs QUESTION---")

        score = answer_grader.invoke("question": question,"generation": generation)

        grade = score['score']

        if grade == "yes":

            print("---DECISION: GENERATION ADDRESSES QUESTION---")

            return "useful"

        else:

            print("---DECISION: GENERATION DOES NOT ADDRESS QUESTION---")

            return "not useful"

    else:

        pprint("---DECISION: GENERATION IS NOT GROUNDED IN DOCUMENTS, RE-TRY---")

        return "not supported"

```

You can see in the code above that we are checking the predictions by the LLM that we use as a classifier. 

Compiling the LangGraph graph. 

This will compile all the agents that we defined and will make it possible to use different tools for your RAG system.

```

# Compile

app = workflow.compile()

# Test

from pprint import pprint

inputs = "question": "Who are the Bears expected to draft first in the NFL draft?"

for output in app.stream(inputs):

    for key, value in output.items():

        pprint(f"Finished running: key:")

pprint(value["generation"])

```

Conclusion

In this blog post, we showed how to build a RAG system using agents with LangChain/ LangGraph, Llama 3, and Milvus. These agents make it possible for LLMs to have planning, memory, and different tool use capabilities, which can lead to more robust and informative responses.

I made it easier to back up your blog with tumblr-utils

Hey friends! I've seen a few posts going around about how to back up your blog in case tumblr disappears. Unfortunately the best backup approach I've seen is not the built-in backup option from tumblr itself, but a python app called tumblr-utils. tumblr-utils is a very, very cool project that deserves a lot of credit, but it can be tough to get working. So I've put together something to make it a bit easier for myself that hopefully might help others as well.

If you've ever used Docker, you know how much of a game-changer it is to have a pre-packaged setup for running code that someone else got working for you, rather than having to cobble together a working environment yourself. Well, I just published a tumblr-utils Docker container! If you can get Docker running on your system - whether Windows, Linux, or Mac - you can tell it to pull this container from dockerhub and run it to get a full backup of your tumblr blog that you can actually open in a web browser and navigate just like the real thing!

This is still going to be more complicated than grabbing a zip file from the tumblr menu, but hopefully it lowers the barrier a little bit by avoiding things like python dependency errors and troubleshooting for your specific operating system.

If you happen to have an Unraid server, I'm planning to submit it to the community apps repository there to make it even easier.

Drop me a message or open an issue on github if you run into problems!

Self Hosting

I haven't posted here in quite a while, but the last year+ for me has been a journey of learning a lot of new things. This is a kind of 'state-of-things' post about what I've been up to for the last year.

I put together a small home lab with 3 HP EliteDesk SFF PCs, an old gaming desktop running an i7-6700k, and my new gaming desktop running an i7-11700k and an RTX-3080 Ti.

"Using your gaming desktop as a server?" Yep, sure am! It's running Unraid with ~7TB of storage, and I'm passing the GPU through to a Windows VM for gaming. I use Sunshine/Moonlight to stream from the VM to my laptop in order to play games, though I've definitely been playing games a lot less...

On to the good stuff: I have 3 Proxmox nodes in a cluster, running the majority of my services. Jellyfin, Audiobookshelf, Calibre Web Automated, etc. are all running on Unraid to have direct access to the media library on the array. All told there's 23 docker containers running on Unraid, most of which are media management and streaming services. Across my lab, I have a whopping 57 containers running. Some of them are for things like monitoring which I wouldn't really count, but hey I'm not going to bother taking an effort to count properly.

The Proxmox nodes each have a VM for docker which I'm managing with Portainer, though that may change at some point as Komodo has caught my eye as a potential replacement.

All the VMs and LXC containers on Proxmox get backed up daily and stored on the array, and physical hosts are backed up with Kopia and also stored on the array. I haven't quite figured out backups for the main storage array yet (redundancy != backups), because cloud solutions are kind of expensive.

You might be wondering what I'm doing with all this, and the answer is not a whole lot. I make some things available for my private discord server to take advantage of, the main thing being game servers for Minecraft, Valheim, and a few others. For all that stuff I have to try and do things mostly the right way, so I have users managed in Authentik and all my other stuff connects to that. I've also written some small things here and there to automate tasks around the lab, like SSL certs which I might make a separate post on, and custom dashboard to view and start the various game servers I host. Otherwise it's really just a few things here and there to make my life a bit nicer, like RSSHub to collect all my favorite art accounts in one place (fuck you Instagram, piece of shit).

It's hard to go into detail on a whim like this so I may break it down better in the future, but assuming I keep posting here everything will probably be related to my lab. As it's grown it's definitely forced me to be more organized, and I promise I'm thinking about considering maybe working on documentation for everything. Bookstack is nice for that, I'm just lazy. One day I might even make a network map...

Seven Sentence Sunday

Thanks, @ramonaflow and @a-noble-dragon for reminding me to check my WIP files. As it happens, because of a computer misadventure, I had to rescue the text below from a prescient backup email attachment I sent myself in March. Right now I'm tearing my hair out trying to find all my files, most of which are in total disarray after two computer ordeals, one re: cloud backup and one re: hard drive rescue. I'm pretty sure this text exists somewhere else, but I can't find it. I'm glad I have backups for my backups for most things I write. I'm giving myself a break after a two-year immersion in Ubi Caritas. I really, seriously need to focus on various non-fic writing projects, but, sigh, wail, I don't wanna. I have two short works in the hopper. Crush at the Courthouse, excepted below, will be the fourth entry in my Overtures series about first meetings. Below, David is immediately intrigued by one of his fellow jurors. Similar to Ruckus in the Rue Cler and Nosedive in the Cockpit, this will be fluffy fun. I'm expecting to end up with 3-5K words; I have about 500 written. The other, Phone Free Weekend, is just what it sounds like. What could coworkers D and P possibly get up to in a cabin in the woods all weekend without any screens to distract them? This one is in pre-outline stage. After I finish these ditties, I SWEAR I'm going to (attempt to ) limit myself to epistolary formats, which are a zillion times easier for me. Okay, enough rambling and buildup for so little content. I'm too tired to edit this post, so here you go: God, Patrick looked so good in his baby blue sweater and tight navy Dockers. Did David just think “Dockers” and cute in the same sentence? Those short brown curls, which definitely need tousling. And his voice. God, his voice. Soft and low. David imagined the things that voice could say. And the things that mouth could do ... What are y'all writing? Tagging from my notifications: @flowertrigger, @wildaloofbutton, @characterassassination-at-9am, @tyfinn, @filet-o-feelings, @mrs-f-darcy, @smallumbrella369, @demora00, @likerealpeopledo-on-ao3

Thoughts on storing a bunch of docker-compse files in a git repo for a home-server

It's a good idea, if something shits the bed you at least have your config files. If you want to backup the data as well what I do is bind the volume to somewhere I choose on my drive and just backup the dir... After shutting down the container obviously

[bored-bi]

so i got Immich [^] working on the homelab as a google photos alternative. super simple to set up, i just made a VM with 4 cpu cores and 6gb ram running debian and installed docker on it. it has a really cool android app that i used to back up all of my photos. the server is saving them to a 2tb hdd and then backing them up to another one every week. im happy to have my photos backed up cuz i didnt have any functional backups before :3 next ill probably come back to the networking course i was doing and then to setting up a vpn

Technical Role of an Odoo Implementation Partner in ERP Rollout Across the US

Deploying Odoo ERP in the US requires more than module configuration—it demands backend development, secure cloud deployment, and logic-driven integration. A qualified Odoo implementation partner takes responsibility for designing, customizing, and scaling ERP environments tailored to US business processes.

With technologies like Python, PostgreSQL, XML, and REST APIs, ERP projects are built from code. Each automation rule, view configuration, and data integration point is written, tested, and deployed under strict technical standards.

Understanding the Technical Execution

Any Odoo implementation service in us begins with a technical audit. Partners review current infrastructure, define data models, and plan module development. Backend logic is written in Python using Odoo's ORM, while user interfaces are customized using XML and Web.

For US businesses, compliance requires more than field mapping. Implementation teams must integrate tax APIs, configure state-based payroll, and localize financial reports. These are not generic templates—they are custom-built scripts and secured logic blocks maintained via Git.

Every Odoo implementation service in us must cover these tasks to ensure technical success and operational reliability.

Secure PostgreSQL queries with constraints

Workflow automation using backend triggers

API layers for US-based POS and payment apps

Role-based access configuration per department

Scheduled data backups and rollback planning

Study Case: Multi-State Retail Company

A retail company with stores across five US states required unified ERP integration. The Odoo implementation service in the US involved developing modules for localized tax logic, integrating legacy POS with token-based REST APIs, and deploying the entire stack using Docker on AWS. Backups, user permissions, and multi-location inventory rules were managed directly through backend logic jobs.

Performance Metrics from Deployment

90+ custom modules aligned to operations

3-week deployment including testing and rollback setup

2x faster report generation after DB optimization

100% automated invoice flows via backend rules

99.9% uptime achieved via container scaling

"Implementation success doesn’t come from templates—it comes from writing the correct logic and deploying it reliably."

Choosing a capable Odoo implementation partner ensures that the ERP system is not just installed but technically sound. When running an Odoo implementation service in us, success comes from enforcing security, building scalable modules, and integrating every logic layer properly. From infrastructure to automation, every component must work in code—because that’s where ERP truly lives.

VPS N8N - Giải pháp tối ưu để triển khai workflow tự động hóa hiệu quả

Trong thời đại chuyển đổi số mạnh mẽ, các doanh nghiệp đang ngày càng chú trọng đến việc tự động hóa quy trình nhằm tiết kiệm thời gian, nhân lực và chi phí vận hành. Một trong những công cụ tự động hóa nổi bật hiện nay là n8n, nền tảng workflow mạnh mẽ và mã nguồn mở. Để tối ưu hiệu suất và độ ổn định khi triển khai n8n, lựa chọn VPS N8N là một hướng đi thông minh và hiệu quả. Vậy VPS N8N là gì, và tại sao ngày càng nhiều lập trình viên, marketer và doanh nghiệp lựa chọn hình thức triển khai này? Hãy cùng tìm hiểu chi tiết qua bài viết sau.

VPS N8N là gì?

VPS N8N là hình thức triển khai nền tảng n8n (Node-Node) trên máy chủ riêng ảo (VPS). Nói cách khác, thay vì sử dụng phiên bản n8n cloud (có giới hạn tính năng và tài nguyên), bạn có thể tự quản lý, tùy biến và mở rộng hệ thống workflow theo ý muốn khi sử dụng VPS.

N8N là một công cụ mã nguồn mở cho phép bạn kết nối hàng trăm ứng dụng với nhau để xây dựng các luồng công việc tự động (workflow automation) như: gửi email, quản lý dữ liệu CRM, xử lý đơn hàng, API calls, phân tích dữ liệu, v.v. Khi kết hợp với một VPS ổn định, hiệu suất cao, bạn hoàn toàn có thể xây dựng hệ thống automation mạnh mẽ mà không phụ thuộc vào bên thứ ba.

Ưu điểm của việc sử dụng VPS N8N

Hiệu suất ổn định và mở rộng linh hoạt

So với việc sử dụng dịch vụ cloud n8n miễn phí hoặc có giới hạn, triển khai n8n trên VPS giúp bạn chủ động về tài nguyên như CPU, RAM, băng thông. Bạn có thể dễ dàng nâng cấp VPS khi cần xử lý lượng workflow lớn hoặc tích hợp nhiều ứng dụng cùng lúc.

Toàn quyền kiểm soát và bảo mật cao

Khi cài đặt n8n trên VPS, bạn có toàn quyền cấu hình hệ thống, bảo mật dữ liệu và xử lý logic theo cách riêng. Điều này đặc biệt quan trọng đối với các doanh nghiệp xử lý dữ liệu khách hàng nhạy cảm hoặc cần tuân thủ các tiêu chuẩn bảo mật nghiêm ngặt.

Tiết kiệm chi phí dài hạn

Thay vì phải trả tiền theo từng workflow, request hoặc user như các nền tảng automation trả phí khác (Zapier, Make...), sử dụng VPS N8N chỉ cần chi trả phí thuê VPS hàng tháng, có thể từ 3 – 10 USD/tháng, tùy cấu hình. Đây là giải pháp tối ưu chi phí cho startup, freelancer hoặc doanh nghiệp vừa và nhỏ.

Tuỳ biến không giới hạn

N8N hỗ trợ viết custom node, webhook và tích hợp API. Khi chạy trên VPS, bạn có thể triển khai thêm các thư viện, cài đặt ứng dụng phụ trợ (Redis, PostgreSQL, etc.) hoặc tích hợp sâu với hệ thống nội bộ doanh nghiệp.

Cài đặt N8N trên VPS có khó không?

Trên thực tế, quá trình cài đặt VPS N8N khá đơn giản, đặc biệt với những người có kiến thức cơ bản về server. Dưới đây là các bước triển khai cơ bản:

Chọn nhà cung cấp VPS: Bạn có thể lựa chọn các nhà cung cấp uy tín như Vultr, Linode, DigitalOcean hoặc các đơn vị Việt Nam như Azdigi, Tinohost.

Cài đặt Docker hoặc Node.js: N8N có thể chạy độc lập hoặc qua Docker container.

Cấu hình n8n: Khai báo thông số môi trường (ENV), webhook URL, đăng ký tài khoản bảo mật, backup định kỳ.

Truy cập giao diện n8n: Thông qua IP VPS hoặc domain riêng.

Nếu bạn không có thời gian hoặc kỹ năng kỹ thuật, bạn có thể thuê các đơn vị chuyên cài đặt VPS N8N trọn gói, chỉ mất khoảng 1 – 2 giờ triển khai.

Ứng dụng thực tế của VPS N8N trong doanh nghiệp

Marketing automation: Kết nối với Google Sheets, Facebook Lead Ads, Email API để tự động hoá chiến dịch.

Bán hàng: Đồng bộ dữ liệu giữa CRM, phần mềm kế toán và chatbot.

Chăm sóc khách hàng: Gửi phản hồi tự động, xử lý ticket nhanh chóng.

IT DevOps: Theo dõi hệ thống, gửi cảnh báo, tự động backup dữ liệu.

Kết luận

VPS N8N là một giải pháp mạnh mẽ, tiết kiệm và linh hoạt cho bất kỳ ai đang muốn xây dựng hệ thống workflow tự động hóa chuyên nghiệp. Việc lựa chọn triển khai n8n trên VPS không chỉ giúp tối ưu hiệu suất mà còn giúp bạn có quyền kiểm soát toàn diện, nâng cao bảo mật và giảm chi phí đáng kể.
