No-Code Agent Building (Women & Underrepresented Genders)

Build Your First AI Agent (No-Code!) 🤖✨ Join LangChain and Tavily for an evening of hands-on building and networking. In this workshop, we'll show you that you don't need to be an engineer to build powerful tools. We'll cover the basic building blocks and principles of agent design. Who Is This For? This is a a space for women and gender-diverse people to learn, build and thrive in tech. We welcome "citizen developers," technical professionals, and non-technical folks alike. Whether you're a product manager, a founder, or just AI-curious, if you can navigate a web browser, you can build an agent. If you are in sales, operations, product management, recruiting, or marketing, this event is for you! What exactly is an Agent? Think of it as a digital assistant that doesn't just follow instructions, but actually thinks and acts to solve a goal—like conducting deep competitor research or managing your inbox. By the end of this hour-long session, you will have built and deployed your very own functional AI agent using LangSmith's No-Code Agent Builder and Tavily’s Search API. What You’ll Learn: The "What": What exactly is an AI agent? The "How": What is an agent framework and why do we use them? The Toolkit: The essential no-code stack for modern AI development. The Build: Step-by-step guidance to create an agent (e.g. an agent to help you automate your email, or conduct research) Event Agenda 6:00 PM – 6:30 PM: Arrivals, Refreshments & Networking 6:30 PM – 6:45 PM: AI Agents 101 – Get to know LangChain, Tavily, and Agent Builder 6:30 PM – 6:50 PM: Demo – See how the Community Manager at LangChain built her Slack Community Bot in under an hour 6:50 PM – 7:50 PM: The Build Session – Hands-on workshop using LangChain & Tavily, with support from Palash Shah (Applied AI Engineer @ LangChain) 7:50 PM – 8:30 PM: Demo "Show & Tell" and Closing Remarks Logistics & Requirements Date: February 5th Time: 6:00 PM - 8:30 PM Location: Tavily Office in Herald Square, Manhattan (Address will be sent to confirmed guests) What to bring: Please bring a laptop + your charger, and an idea for a problem you want to tackle with an agent!

Webinar: Agent Observability Powers Agent Evaluation

Join Harrison Chase, Co-founder and CEO at LangChain, for a technical deep dive into why building reliable AI agents requires new approaches to observability and evaluation. AI agents do not fail like traditional software. When an agent takes hundreds of steps, repeatedly calls tools, updates state, and still produces the wrong result, there is no stack trace to inspect. Nothing crashed. What failed was the agent’s reasoning. In this webinar, we’ll explore why observability and evaluation for agents are fundamentally different from what most software teams are used to, and why traces become the primary source of truth when you start building agentic systems. We’ll cover how debugging shifts from finding a broken line of code to understanding where an agent’s reasoning went off track, why evaluating agents requires looking at trajectories and decisions rather than just final outputs, and how production traces enable both offline and online evaluation. We’ll also walk through the core primitives of agent observability, including runs, traces, and threads, and show how teams use them together to iteratively improve agent behavior with LangSmith. This session is for engineers and teams building agents who are encountering non-deterministic behavior and want a clearer mental model for how to debug, evaluate, and ship agents that actually work. Agenda: 12:00pm: Presentation by Harrison 12:30pm: Q&A session About LangChain: LangChain provides the agent engineering platform and open source frameworks to help companies ship reliable agents.

LangSmith 101

​Join us for a live demo of on how leading engineering teams use observability and evaluation to ship reliable, production-ready AI agents faster with LangSmith.​Learn the foundations for understanding, improving, and confidently deploying AI agents. Get practical steps on how to debug non-deterministic agent behavior, iterate on performance, and ship reliably across any frameworks and models.​What you’ll learn:How to get end-to-end visibility into agent behavior with tracing for each agent step, tool calls, conversation, latency, error, and token count.Practical ways to debug and improve agents using production traces, insights, and iterative prompt/tool refinement.How to set up evaluations (datasets, experiments, and subject matter expert annotations) to measure quality and prevent regressions.

Closing the Loop: What does a production eval flywheel look like

[AMA] Debugging Deep Agents

Deep agents don’t follow clean, predictable paths, they reason across multiple steps, call tools, and adapt dynamically at runtime. That makes them powerful, but also hard to debug, trace, and evaluate.In this live AMA, we’ll dig into practical ways to instrument and understand agent behavior using LangSmith. We’ll cover how to trace execution across complex workflows, inspect intermediate steps, and design evaluation strategies that actually reflect real-world performance.We’ll also walk through how to measure effectiveness across runs, catch failure modes early, and iterate with confidence in non-deterministic systems.Bring your questions, we’ll keep it hands-on and focused on what works in production.

LangSmith 102: Agents That Actually Work

Agents don’t run themselves, once you move into multi-step workflows, planning, parallel subagents, long-running tasks, production becomes an infrastructure problem. Context has to live somewhere. Failures have to be recoverable. Humans need to be able to step in without breaking the run.In this live demo, we'll show what it actually takes to build and deploy agents that hold up in production. We'll use Deep Agents, our open source harness for long-running autonomous work, and deploy it with LangSmith Deployment, a durable runtime with checkpointing, tracing, and scaling built in.We’ll cover how to:Orchestrate multi-step agent execution across tools and decisionsConnect agents to real systems with the right guardrailsManage state, memory, and context across runsTrace and debug agent behavior step-by-stepHandle failures, retries, and scaling in real environmentsWe’ll show what it takes to run agents reliably at scale and how teams are deploying and operating agents that actually work.

How to Operationalize the Agent Improvement Loop

Improving agents takes more than making changes in production. The teams getting better are building systems that learn from real behavior. Every trace is useful data: a record of how an agent actually performed that can be enriched with evaluators, human feedback, and annotations to drive smarter iteration.In this session, join LangChain’s Head of Product, Sam Crowder, for a practical look at the agent improvement loop and how teams use traces as the foundation for continuous improvement. We’ll walk through how to capture real agent behavior, enrich traces with automated evals and human review, turn recurring patterns into reusable evaluation datasets, and validate changes before shipping.We’ll cover how to:Capture end-to-end traces across prompts, tool calls, and intermediate stepsEnrich traces with automated evals and human feedback to surface issues at scaleTurn real agent behavior into reusable offline evaluation datasetsValidate improvements in CI/CD before they reach productionWalk away with a practical framework for turning traces into a repeatable improvement system, operationalizing evals, and building agents that get better over time.

LangSmith 102: How to run deep agents in production

Agents don’t run themselves, and once you move into multi-step workflows, running them in production becomes a systems problem.In this live demo, we’ll walk through how to run deep agents with LangSmith, showing what it actually looks like to move from simple prompts to production-ready workflows.We’ll cover how to:Orchestrate multi-step agent execution across tools and decisionsConnect agents to real systems with the right guardrailsManage state, memory, and context across runsTrace and debug agent behavior step-by-stepHandle failures, retries, and scaling in real environmentsRather than staying high-level, we’ll show how these pieces come together in practice, so you can see what it takes to run agents reliably at scale.The core idea: prompts decide what to do next, but the runtime is what makes deep agents actually work in production.Join us for a hands-on session focused on how teams are deploying and operating agents in the real world.

[Customer AMA] Scaling Agents Across Your Organization with LangSmith Fleet

Building agents is no longer just a developer workflow, it’s becoming a company-wide capability.In this AMA, we’ll explore how teams are using LangSmith Fleet to build, manage, and scale agents across the organization. From creating agents with natural language to managing identity, permissions, and tool access, Fleet introduces a new layer of infrastructure for how agents operate in production.We’ll cover how to:Build and deploy agents without heavy engineering overheadManage agent identity, access, and governance across teamsConnect agents to real workflows (Slack, tools, internal systems)Turn agents from experiments into reliable, reusable systemsWhether you’re thinking about enabling non-technical teams, scaling agent usage, or bringing structure to how agents are deployed across your company, this session will focus on what it actually takes.Bring your questions, we’ll keep it practical and grounded in real production use cases.

[Customer AMA] LangSmith Deployment: From Testing to Production

Deploying agents isn’t just about getting them live, it’s about making sure they actually work in production.In this AMA, we’ll walk through what it takes to deploy agents with LangSmith, from testing and validation to monitoring real-world performance. We’ll cover how to move from local experimentation to production-ready systems, how to catch issues early, and how to build confidence before and after deployment.We’ll also dig into how teams are using traces and evals as part of their deployment workflow, so every release is grounded in real behavior, not assumptions.Bring your questions, we’ll keep it practical and focused on what works in production.
