# Multi-Agents (Sequential) with Reasoning – Connect to any database - o3-mini / Deepseek-R1 / Flash-2.0. Built with Flowise.

Built with Flowise. Leverage as a reusable component

With agent templates, tool schemas and source codes.

## 6 database agent options

The Analyzer micro-app on REX-3 ([tigzig.com](http://tigzig.com/)) offers 6 agent options, all capable of:

* connecting to any database (with credentials)
* natural-language-to-SQL
* natural-language to python (for charts & stats)

App also allows on-the-fly Postgres database for file uploads and temp use

**AI backend is on Flowise AI. Leverage as a reusable component:**

* directly via Flowise's native UI (Click </> → Share Chatbot → Live)
* plugged into any UI via API (as in REX-3)
* integrated into automated workflows via API

Easy to setup, modify and maintain.

## Standalone General Analyst

Single-agent setup for regular queries & simple analysis. Uses o3-mini; for complex cases, I use gpt-4o

## Multi-Agents (technically sequential agents in Flowise, Backend: LangGraph)

Three-agent flow: Gemini-Flash-2 / o3-mini / Deepseek-R1. Agent flow:

* **Router Agent** → Determines if a query goes to General or Advanced Analyst
* **General Analyst** → Same as standalone version above
* **Advanced Analyst** →
  * Step 1: Reasoning LLM (o3-mini / Flash-2 / Deepseek-R1) generates analysis plan & SQL
  * Step 2: gpt-4o agent verifies query accuracy, executes, and returns results

## Multi (Sequential) Agents with Additional Debugging

Still in testing. Similar to sequential agents but with:

* one has and additional error-checking step
* other is a debugger agent for routing based on user request

## Take them for a spin

Feel free to test out with different data/query complexity/agent choices-no API key needed. Connect to your database or use the temporary Postgres DB (created on-the-fly for file uploads). Upload your own files or just hit the 'Sample' button for sample file upload.

## Source Codes/ Resources
