Agent Observability with LangSmith, Langfuse, and Arize: A Hands-On Comparison 

Your AI agent works great in testing. Then you ship it, and something kinda breaks. A tool called loops forever, like it never learns. A retrieval step returns garbage and costs spike. You have no idea why, at all. That’s the agent observability problem. And if you’re building with LLMs, you need to solve it […]

AI Workflows for Sales Teams: Prospect Research, Lead Qualification, and CRM Updates on Autopilot Using LangGraph  

Sales teams spend hours every day on tasks that should never see a human. Research a prospect, score them against their fit, and put it all into a CRM. These are repeatable, rule based processes AI workflows driven by multi-agent systems can do all three, with speed and consistency that no human team can match.

Build a Claude Cowork-Like Browser Agent Using Playwright MCP and Claude Desktop 

Claude Cowork shifts AI from chat-based assistance to task delegation. Instead of giving users instructions, it performs actions directly on the user’s computer, files, applications, and browser workflows. Combined with Playwright MCP, Claude Desktop can open pages, click buttons, fill forms, extract data, and debug interfaces in a far more structured way than screenshot-based automation.

23 Tips for Smart Claude Code Token Saving and Workflow Optimization

Using Claude Code in large projects can lead to skyrocketing token costs. A 2025 Stanford study reveals developers waste thousands of tokens daily, draining budgets as unchecked context limits pile up. By setting strict boundaries from the outset, teams can reduce costs without compromising code quality. Optimizing token usage and context window sizes early on

Compressing LSTM Models for Retail Edge Deployment: A Practical Comparison

There can be some practical constraints when it comes to deploying the AI models for retail environments. Retail environments can include store-level systems, edge devices, and budget conscious setup, especially for small to medium-sized retail companies. One such major use case is demand forecasting for inventory management or shelf optimization. It requires the deployed model

Build an AI Meeting Summarizer & Action Planner with Claude Code + MCP 

Teams across companies lose meeting notes and action items after discussions. This guide builds a lasting fix: an AI Meeting Summarizer and Action Planner using Claude Code with MCP. It processes transcripts into structured summaries with tasks, decisions, and calendar invites, connects to Google Calendar and Gmail, and stores everything in SQLite. MCP acts as

Harness Engineering with LangChain DeepAgents and LangSmith

Struggling to make AI systems reliable and consistent? Many teams face the same problem. A powerful LLM gives great results, but a cheaper model often fails on the same task. This makes production systems hard to scale. Harness engineering offers a solution. Instead of changing the model, you build a system around it. You use prompts, tools, middleware, and evaluation to guide the model toward reliable outputs. In this article, I have built a reliable AI coding agent using LangChain’s DeepAgents and LangSmith. We also test its performance using standard benchmarks. What is Harness Engineering? Harness engineering focuses on building a structured system around an LLM to improve reliability. Instead of changing the model itself, you control the environment in which it operates. A typical harness includes a system prompt, tools or APIs, a testing setup, and middleware that guide the model’s behavior. The goal is simple: improve task success and manage costs while using the same underlying model. In this tutorial, we use LangChain’s DeepAgents library to demonstrate this approach. DeepAgents acts as an agent harness with built-in capabilities such as task planning (to-do lists), an in-memory virtual file system, and sub-agent spawning. These features help structure the agent’s workflow and make the system more reliable. Also Read: A Guide to LangGraph and LangSmith for Building AI Agents Evaluation and Metrics To evaluate the system, we need clear performance metrics. In this tutorial, we build a coding agent and test it using the HumanEval benchmark. HumanEval consists of 164 hand-crafted Python problems designed to evaluate functional correctness. We use two common evaluation metrics: Building a Coding Agent with Harness Engineering We will build a coding agent and evaluate it on benchmarks and metrics that we will define. The agent will be implemented using the deepagents library by LangChain and

Nanochat Can Now Train a GPT-2 Level Model in Just 2 Hours

AI development is accelerating fast. Advances in hardware, software optimization, and better datasets now allow training runs that once took weeks to finish in hours. A recent update from AI researcher Andrej Karpathy shows this shift clearly: the Nanochat open-source project can now train a GPT-2 model on a single node with 8× NVIDIA H100

Building a Self-Improving AI Support Agent with Langfuse 

Building an LLM prototype is quick. A few lines of Python, a prompt, and it works. But Production is a different game altogether. You start seeing vague answers, hallucinations, latency spikes, and strange failures where the model clearly “knows” something but still gets it wrong. Since everything runs on probabilities, debugging becomes tricky. Why did
