What are Langsmith and Langchain?

Langchain is one of the fastest-developing open-source projects in history, in large part because of the explosion of interest in LLM's. It exists to make the application development easier.

On the other hand, Langsmith is a revolutionary platform to help developers clear the gaps between prototypes to production. It is designed to build and repeat on that can harness the power and solve the complexities of LLMs.

In this blog, we will know why Langsmith exists, what users or companies can actually do with it, and how is it different from Langchain.

In short, we can say
Langchain was only limited to creating prototypes. However, with Langsmith users have the ability to convert ideas into final products (production).

Why should you use Langsmith?

When you establish a system that relies on user input, you might notice that the outcomes can differ each time. Even a small change in the input prompt can lead to varying results, resulting in uncertainty. However, with the assistance of Langsmith, you gain the ability to comprehend the underlying processes.

Let’s dive deeper into the features:

You will get to know under the hood what processes are involved.

  • How many tokens did it use?
  • Cost of tokens.
  • What is the API cost?
  • We can visualize our runs.

# Feature 1: Visualizing the whole process:

Langsmith offers a visual representation of the steps involved in an LLM development process. This can be very helpful to understand how the application is working and determine the potential problems. It is further divided into the following parts:

Action: A user input that the LLM takes to process a query.

Action Input: The input prompt that an LLM application understands by the user input.

Observation: The things or parameters that an LLM model is going to take into account.

Thought: The LLM's internal reasoning for taking an action.

Repeat the action input, observation, and thought several times: This is done to ensure that the LLM is consistently producing the same results for a given query.

Final Answer: The final output of the LLM after repeating the action input, observation, and thought one or several times according to the requirement.

# Feature 2: Developing a dataset:

Langsmith can be used to create a dataset of LLM applications. This dataset can be considered to train other LLM models or evaluate the performance of existing LLM development models.

Runtime: The time it takes for the LLM application to process a query.

Tokens used: The number of tokens used by the LLM application to process a query.

Input: The input prompt that is given to the LLM application.

Tags: The tags that are associated with a query.

Start time: The time at which the LLM application begins processing a query.

Latency: The time it takes for the LLM application to produce a response.

# Feature 3: Collaborate with teams

Langsmith may be utilized to collaborate with the teams on LLM applications. This can be done by sharing LLM applications, datasets, and visualizations. LLM applications can also be tracked over time with Langsmith's version control.

# Feature 4: Dataset Evaluation

Langsmith can be used to evaluate the performance of datasets for LLM applications. This can be done by running LLM applications on the datasets and measuring the accuracy and latency of the results. Langsmith's solution for production also provides a variety of visualizations that can be used to analyze the performance of datasets.

Who can benefit from Langsmith?

  • Companies: Langsmith is not just for individuals. It’s a game changer for companies. As this can contribute to significant improvements in production efficiency.
  • AI enthusiasts: LangSmith can help you learn more about large language models and how to use them to create innovative applications.
