6 no-code LLM, Agents, and RAG builder tools
Continuing from open-source…
We scroll through and test several GitHub repos every week to find promising projects that would be helpful for AI engineers.
Here are 6 no-code LLM, Agents, and RAG builder tools we found:
RAGFlow
RAGFlow is a RAG engine for deep document understanding!
It lets you build enterprise-grade RAG workflows on complex docs with well-founded citations.
Supports multimodal data understanding, web search, deep research, etc.
100% open-source with 59k+ stars!
xpander
xpander is a framework-agnostic backend for agents that manages memory, tools, multi-user states, events, guardrails, etc.
While it is not a core no-code tool, you can build, test, and deploy Agents by primarily using the UI.
Compatible with LlamaIndex, CrewAI, etc.
Transformer Lab
Transformer Lab is an app to experiment with LLMs:
Train, fine-tune, or chat.
One-click LLM download (DeepSeek, Gemma, etc.)
Drag-n-drop UI for RAG.
Built-in logging, and more.
A 100% open-source and local!
Llama Factory
LLaMA-Factory lets you train and fine-tune open-source LLMs and VLMs without writing any code.
Supports 100+ models, multimodal fine-tuning, PPO, DPO, experiment tracking, and much more!
100% open-source with 50k stars!
Langflow
Langflow is a drag-and-drop visual tool to build AI agents.
It lets you build and deploy AI-powered agents and workflows. Supports all major LLMs, vector DBs, etc.
100% open-source with 82k+ stars!
AutoAgent
AutoAgent is a zero-code framework that lets you build and deploy Agents using natural language.
It comes with:
Universal LLM support
Native self-managing Vector DB
Function-calling and ReAct interaction modes.
100% open-source with 5k stars!
👉 Over to you: What no-code AI builder tools will you add here?
[Video] A technique to understand TP, TN, FP and FN
Do you struggle to classify predictions as one of TP, TN, FP, and FN?
If yes, here’s a video that explains a simple technique:
Essentially, when labeling any binary classification prediction, ask two questions:
Question 1) Did the model get it right?
The answer will be either Yes or No.
Yes means True.
No means False.
Question 2) What was the predicted class?
The answer will be either Positive or Negative.
Next, just combine the above two answers to get the final label.
For instance, say the actual and predicted class were positive.
Question 1) Did the model get it right?
Answer: Yes, which means TRUE.
Question 2) What was the predicted class?
Answer: POSITIVE.
The final label: TRUE POSITIVE.
👉 Over to you: Do you know any other techniques to label binary classification predictions?
Thanks for reading!
P.S. For those wanting to develop “Industry ML” expertise:
At the end of the day, all businesses care about impact. That’s it!
Can you reduce costs?
Drive revenue?
Can you scale ML models?
Predict trends before they happen?
We have discussed several other topics (with implementations) that align with such topics.
Here are some of them:
