The Web API at GitHubPython FastAPI with JWT Auth serving a Tool-Calling AI Agent using LangChain - hosted at Vercel Cloud using Serverless Functions
A production-style FastAPI backend built with LangChain, Groq LLMs, and JWT authentication. The system implements a modern tool-calling AI agent architecture that automatically decides when to use external tools such as Wikipedia for factual retrieval

The Web API at GitHubPython FastAPI with JWT Auth serving a Tool-Calling AI Agent - hosted at Render Cloud by Webservice
The AI agent implements a modern 3-phase Tool Agent Pipeline (Plan → Execute → Synthesize) where tools are safely selected, executed, and used to generate grounded responses using a minimal of Langchain

The Web API at GitHubPython FastAPI with JWT Auth serving a ReAct-inspired AI agent system - hosted at Vercel Cloud using Serverless Functions
The AI agent system follows a lightweight ReAct-inspired flow. A simple router determines when to use a Wikipedia tool, and the retrieved context is passed to the model to generate the final answer using a minimal of Langchain

The Web API at GitHubReAct (Reason + Act)
Concept: Alternate between reasoning steps and taking actions (tool calls, API calls, etc.)
Flow:
Strengths: Multi-step problem solving, tool orchestration, grounded responses
Use case: Complex question answering, multi-tool agents, decision-making systems
Tool-Calling / Tool-Augmented Agents
Concept: The LLM acts as a controller that decides whether to call external tools
Flow:
Strengths: Reduces hallucinations, improves grounding, enables use of APIs and external systems
Use case: Wikipedia-style assistants, math solvers, structured data retrieval
Reflex / Reactive Agents
Concept: Immediate response without planning or multi-step reasoning
Flow: Input → Response
Strengths: Very fast, low complexity, low cost
Use case: Chatbots, simple Q&A systems
Plan-and-Execute / Hierarchical Planning Agents
Concept: The agent first creates a plan, then executes steps sequentially
Flow:
Strengths: Strong for complex workflows and multi-step tasks
Use case: Automation systems, workflow orchestration, research agents
Debate / Self-Reflection Agents
Concept: Multiple candidate outputs are generated and evaluated before final selection
Flow:
Strengths: Reduces errors, improves reliability, reduces hallucinations
Use case: Code review, summarization, high-accuracy Q&A
Memory-Augmented Agents
Concept: The agent stores and retrieves long-term memory to maintain context
Flow:
Strengths: Personalization, continuity, long-term context awareness
Use case: Personal assistants, long-running agents, adaptive systems
