Build an AI Agent in 60 Lines of Python Before Reaching for LangChain

Watch: Build an AI Agent From Scratch in Python - Tutorial for Beginners by Tech With Tim Understanding the agent loop stopped being optional the moment you tried to change one thing in a framework demo and couldn't find where the loop lived. Quickstarts run fine until you need to touch them. A…

I am an AI/ML researcher with 150+ citations and 16 published research papers. I have three tier-1 publications, including Internet of Things (Elsevier), Biomedical Signal Processing and Control (Elsevier), and IEEE Access. In my research journey, I have collaborated with NASA Glenn Research Center, Cleveland Clinic, and the U.S. Department of Energy for various research projects. I am also an official reviewer and have reviewed over 100 research papers for Elsevier, IEEE Transactions, ICRA, MDPI, and other top journals and conferences. I hold a PhD from Cleveland State University with a focus on large language models (LLMs) in cybersecurity, and I also earned a master’s degree in informatics from Northeastern University.

Express for AI Inference in 2026: Build a Low-Latency RAG API with PGVector or FAISS

Latency stopped being optional the moment you put retrieval in front of an LLM. Every millisecond your vector search burns is a millisecond before the first token appears. Express stays lean by design, which leaves the vector store owning most of your retrieval headroom. This guide is a project…

Build a Production AI App: Where Vibe Coding Platforms Break Down

Your prototype stopped being optional the moment a real user typed a real password into it. Before that, it was a demo. Now it's a liability with a login screen, and the habits that got you this far won't carry you further. Vibe coding is a good way to explore. It can accelerate exploration, reduce…

AWQ in Practice: Quantize LLMs for Faster AI Inference Without Killing Output Quality

AWQ cuts 70B model serving costs from $0.757 to $0.253 per million tokens by moving from two GPUs to one. Llama 3.3 70B quantized to INT4 with AWQ drops 2 MMLU points and 3 HumanEval points versus full precision. AWQ INT4 brings a 70B model's VRAM down from 140GB to roughly 40GB, fitting it on a…

Beyond Basic RAG: Self-RAG, CRAG, and RA-DIT Patterns That Actually Improve Retrieval

The short version: Basic RAG follows a rigid sequence: retrieve k passages, insert them into the prompt, generate an answer. The weakness often sits in that fixed sequence, not in the retriever. The RAG survey describes the shift from basic retrieval to modular and adaptive designs. Self-RAG offers…
