Trace and Monitor Any AI/LLM App
If you are building with LLMs, you absolutely need traceability.
Opik is an open-source, production-ready end-to-end LLM evaluation platform.
It allows developers to test their LLM applications in development, before a release (CI/CD), and in production.
Here’s an example with CrewAI below:
All you need to do is this:
Put your LLM logic inside a function.
Add the
@trackdecorator.
Done!
After this, Opik will track everything within your AI application, from LLM calls (with cost) to evaluation metrics and intermediate logs.
If you want to dive further, we also published a practical guide on Opik to help you integrate evaluation and observability into your LLM apps (with implementation).
It has open access to all readers.

11 Most Important DS Plots
This visual depicts the 11 most important and must-know plots in DS:
Today, let’s understand them briefly and how they are used.
1) KS Plot:
It is used to assess the distributional differences.
The idea is to measure the maximum distance between the cumulative distribution functions (CDF) of two distributions.
The lower the maximum distance, the more likely they belong to the same distribution.
2) SHAP Plot:
It summarizes feature importance to a model’s predictions by considering interactions/dependencies between them.
It is useful in determining how different values (low or high) of a feature affect the overall output.
We covered model interpretability extensively in our 3-part crash course. Start here: A Crash Course on Model Interpretability →
3) ROC Curve:
It depicts the tradeoff between the true positive rate (good performance) and the false positive rate (bad performance) across different classification thresholds.
The idea is to balance TPR (good performance) vs. FPR (bad performance).
4) Precision-Recall Curve:
It depicts the tradeoff between Precision and Recall across different classification thresholds.
5) QQ Plot:
It assesses the distributional similarity between observed data and theoretical distribution.
It plots the quantiles of the two distributions against each other.
Deviations from the straight line indicate a departure from the assumed distribution.
6) Cumulative Explained Variance Plot:
It is useful in determining the number of dimensions we can reduce our data to while preserving max variance during PCA.
Read the full article on PCA here for more clarity: Formulating the Principal Component Analysis (PCA) Algorithm From Scratch.
7) Elbow Curve:
The plot helps identify the optimal number of clusters for the k-means algorithm.
The point of the elbow depicts the ideal number of clusters.
8) Silhouette Curve:
The Elbow curve is often ineffective when you have plenty of clusters.
Silhouette Curve is a better alternative, as depicted above.
9) Gini-Impurity and Entropy:
They are used to measure the impurity or disorder of a node or split in a decision tree.
The plot compares Gini impurity and Entropy across different splits.
This provides insights into the tradeoff between these measures.
10) Bias-Variance Tradeoff:
It’s probably the most popular plot on this list.
It is used to find the right balance between the bias and the variance of a model against complexity.
11) Partial Dependency Plots:
Depicts the dependence between target and features.
A plot between the target and one feature forms → 1-way PDP.
A plot between the target and two feature forms → 2-way PDP.
In the leftmost plot, an increase in temperature generally results in a higher target value.
