What you will gain after the course

  • AI Agent-Specific Evaluation Methodologies and Practical Know-How

  • Establishing a "data"-driven decision-making system rather than one based on "intuition"

  • Dramatic reduction in development and testing costs

  • Error resolution and debugging techniques for real-world service operations

The AI agent you've worked so hard on
Is it okay to deploy?



🤯

I only changed one prompt, but the feature that used to work fine is suddenly lagging.

😢

I upgraded to the latest model because they said it was smarter, but it feels like the performance has actually dropped compared to before.

🤔

I've improved the features, but I don't know how much testing is needed to feel confident about deploying.

😳

I feel lost on how to explain the agent's performance to my team leader, who is asking about it right before deployment.


There is only one reason why we hesitate.
When we change prompts, models, or logic,
we lack the confidence that the overall performance will truly improve.

What do you need when you need certainty?
It is none other than 'AI Agent Evaluation'.

The start of a stable service
AI Agent Evaluation

AI agents have characteristics that are different from general software.


Characteristics of AI agents that differ from existing software

Indeterminacy of AI

Because the results vary every time even with the same prompt, there is no guarantee that it will always be good just because it was good once.

Unstructured problems

Most problems handled by agents do not have a single correct answer. Therefore, quality cannot be captured by Pass/Fail alone.

Dynamic System

Because agents constantly change due to prompt modifications, model updates, and changes in user input/patterns, continuous quality verification is necessary.

Ultimately,

If you fail to properly monitor changes in your AI agent,
your service could collapse at any time.



That's why we're sharing

Immediately applicable in practice
AI Agent Evaluation Methods


We cover the entire process that can be directly applied to practical work, from building datasets to evaluating agents and comparing performance according to the evaluation process.


01.

Cost- and time-saving
Golden Dataset Construction

Learn three methods for creating domain-specific evaluation data using AI.

RAGAS

Automatically generate question-answer QA datasets

Custom Agent

Generate domain-specific data with custom prompts and tools

Claude Code Skill

Expanding small-scale data into large-scale datasets


02.

Adopted by Big Tech
Agent Evaluation Methods

We will show you how to verify where and why an agent failed, using methods adopted by Anthropic, Google, and Amazon.


E2E + Component Evaluation

E2E is an evaluation method that determines the success or failure of the final result. However, for complex practical agents involving 10 to 20 steps, Component evaluation must be used alongside it. By verifying each step, you can pinpoint exactly whether the issue lies in the search or the tool selection, allowing for efficient debugging.


03.

Anthropic's Guide on
How to Quantify Agent Performance

We introduce two methods to objectively compare and evaluate an agent's maximum performance and consistency.


pass@k

A metric to check the maximum performance an agent can achieve

pass^k

A metric to verify how consistently the agent operates


📚

Introduction to the Learning Curriculum

Section 1

Necessity of AI Agent Evaluation

Explains the definition of AI agent evaluation and why it is essential. Explores ways to improve the quality of AI services and reduce development and testing costs by establishing a data-driven decision-making system.


Section 2

Golden Dataset Construction Strategy

This covers how to create a Golden Dataset. It includes hands-on practice in building datasets using LangSmith settings, custom agents, and various document types.


Section 3

Designing AI Agent Evaluation Metrics

Learn how to design evaluation metrics to measure the performance of AI agents. Analyze accuracy, document retrieval, and tool usage efficiency through end-to-end and component-specific evaluation methods.


Section 4

Advanced Quantitative Analysis of Agent Performance

You will learn how to numerically analyze the maximum performance and reliability of agents using advanced metrics such as Pass@k and Pass^k. Through this, you will conduct an in-depth evaluation of the agent's potential and stability.


We can solve the concerns of these people!


📌

AI Agent Developer

Those who feel anxious that existing functions might unexpectedly malfunction whenever they modify prompts to improve model performance

📌

AI Service Operations Manager

Those who are worried that overall service stability might decline during model updates,
and those who struggle with making decisions based on intuition without clear evaluation metrics.

📌

LLM-based Service Planner

Those who want to communicate based on specific data and metrics rather than "intuition"
when conveying performance improvement requirements for AI agents to their team.

Who is this course right for?

  • A developer who feels anxious that every time they fix a single line of a prompt, another feature might break.

  • A planner who wants to make decisions based on data and metrics rather than 'feelings' when communicating with the development team

  • Developers who want to go beyond the basics and develop AI agents at a professional, practical level

    Jason's courses are ones I always trust and sign up for. I have taken all of the instructor's LangChain-related courses, and thanks to them, I am currently working as a junior AI Engineer. I had been worrying a lot about evaluation in my actual work, and since this course was released at the perfect time, I am planning to learn and apply it quickly. Thank you for always providing high-quality lectures. Additionally, this is a separate question, but I just found out that you recently published a book. I haven't purchased it yet, but I'd like to ask if it's worth studying with the book even though I've already taken all the courses. Your lectures feel like having a great mentor because you always explain and share things from the student's perspective. Once again, thank you for the great lectures as always. :)

      Hello Seonggyu! Thank you for the great feedback. I'm so proud to hear that taking this course helped you in your career as an AI engineer, as it feels like the effectiveness of the course has been proven. Thank you for sharing. The book does cover a slightly wider variety of evaluation strategies and methods than the course. However, since the course covers evaluation theory sufficiently, I don't think you necessarily need to purchase the book if you've already completed the lectures (I probably shouldn't be saying this as someone selling the book 😅). I look forward to seeing you again with another great course!

    • Ah. Honestly, I'm so grateful and it makes me trust you even more because you were so straightforward..!! :) I'll continue to sign up for the early bird courses first thing in the future. I look forward to working with you!
