To get started, create an account by clicking “Log in” on PromptLayer. Once logged in, click the button to create an API key and save this in a secure location (Guide to Using Env Vars).

Once you have that all set up, install PromptLayer using pip.

pip install promptlayer

PromptLayer python library has support for both OpenAI and Anthropic LLMs!

Set up a PromptLayer client in your python file.

from promptlayer import PromptLayer
promptlayer_client = PromptLayer()

Optionally, you can specify the API key in the client.

promptlayer_client = PromptLayer(api_key="pl_****")

​
OpenAI

In the Python file where you use OpenAI APIs, add the following. This allows us to keep track of your requests without needing any other code changes.

You can then use openai as you would if you had imported it directly.

Your OpenAI API Key is never sent to our servers. All OpenAI requests are made locally from your machine, PromptLayer just logs the request.

There is only one difference… PromptLayer allows you to add tags through the pl_tags argument. This allows you to track and group requests in the dashboard.

Tags are not required but we recommend them!

completion = client.chat.completions.create(
  model="gpt-3.5-turbo",
  messages=[
    {"role": "system", "content": "You are an AI."},
    {"role": "user", "content": "Compose a poem please."}
  ],
  pl_tags=["getting-started"]
)

After making your first few requests, you should be able to see them in the PromptLayer dashboard!

Here is a complete code snippet:

from promptlayer import PromptLayer
promptlayer_client = PromptLayer()

# Swap out 'from openai import OpenAI'
OpenAI = promptlayer_client.openai.OpenAI

client = OpenAI()
completion = client.chat.completions.create(
  model="gpt-3.5-turbo",
  messages=[
    {"role": "system", "content": "You are an AI."},
    {"role": "user", "content": "Compose a poem please."}
  ],
  pl_tags=["getting-started"]
)
print(completion.choices[0].message)

​
Anthropic

Using Anthropic with PromptLayer is very similar to how to one would use OpenAI.

Below is an example code snippet of the one line replacement:

from promptlayer import PromptLayer
promptlayer_client = PromptLayer()

# Swap out 'from anthropic import Anthropic'
anthropic = promptlayer_client.anthropic

client = anthropic.Anthropic()

completion = client.completions.create(
    prompt=f'{anthropic.HUMAN_PROMPT} How many toes do dogs have? {anthropic.AI_PROMPT}',
    stop_sequences=[anthropic.HUMAN_PROMPT],
    model='claude-v1-100k',
    max_tokens_to_sample=100,
    pl_tags=['animal-toes']
)

print(completion)

Here is how it would look like on the dashbaord:

​
Async Support

PromptLayer supports asynchronous operations, ideal for managing concurrent tasks in non-blocking environments like web servers, microservices, or Jupyter notebooks.

​
Initializing the Async Client

To use asynchronous non-blocking methods, initialize AsyncPromptLayer as shown:

from promptlayer import AsyncPromptLayer

# Initialize an asynchronous client with your API key
async_promptlayer_client = AsyncPromptLayer(api_key="pl_****")

​
Async Usage Examples

The asynchronous client functions similarly to the synchronous version, but allows for non-blocking execution with asyncio. Below are example uses.

​
Example 1: Async Template Management

Use asynchronous methods to manage templates:

import asyncio
from promptlayer import AsyncPromptLayer

async def main():
    async_promptlayer_client = AsyncPromptLayer(api_key="pl_****")

    # Fetch a template asynchronously
    template = await async_promptlayer_client.templates.get("Test1")
    print(template)

    # Fetch all templates asynchronously
    templates = await async_promptlayer_client.templates.all()
    print(templates)

# Run the async function
asyncio.run(main())

​
Example 2: Async Workflow Execution

Run workflows asynchronously for better efficiency:

import asyncio
from promptlayer import AsyncPromptLayer

async def main():
    async_promptlayer_client = AsyncPromptLayer(api_key="pl_****")

    response = await async_promptlayer_client.run_workflow(
        workflow_name="example_workflow",
        workflow_version=1,
        input_variables={"num1": "1", "num2": "2"},
        return_all_outputs=True,
    )
    print(response)

# Run the async function
asyncio.run(main())

​
Example 3: Async Tracking and Logging

Track and log requests asynchronously:

import asyncio
from promptlayer import AsyncPromptLayer

async def main():
    async_promptlayer_client = AsyncPromptLayer(api_key="pl_****")

    # Track metadata asynchronously
    request_id = "pl_request_id_example"
    await async_promptlayer_client.track.metadata(request_id, {"key": "value"})

    # Log request asynchronously (for detailed logging, refer to the custom logging page)
    await async_promptlayer_client.log_request(
        provider="openai",
        model="gpt-3.5-turbo",
        input=prompt_template,
        output=output_template,
        request_start_time=1630945600,
        request_end_time=1630945605,
    )

# Run the async function
asyncio.run(main())

For more information on custom logging, please visit our Custom Logging Documentation.

​
Example 4: Asynchronous Prompt Execution with run Method

You can execute prompt templates asynchronously using the run method. This allows you to run a prompt template by name with given input variables.

import asyncio
from promptlayer import AsyncPromptLayer

async def main():
    async_promptlayer_client = AsyncPromptLayer(api_key="pl_****")

    # Execute a prompt template asynchronously
    response = await async_promptlayer_client.run(
        prompt_name="TestPrompt",
        input_variables={"variable1": "value1", "variable2": "value2"}
    )
    print(response)

# Run the async function
asyncio.run(main())

In this example, replace “TestPrompt” with the name of your prompt template, and provide any required input variables.

​
Supported Methods: Synchronous vs. Asynchronous

The following table provides an overview of the methods currently available in both synchronous and asynchronous versions of the PromptLayer client:

MethodDescriptionSynchronous VersionAsynchronous Version
templates.get()Retrieves a template by name.promptlayer_client.templates.get()async_promptlayer_client.templates.get()
templates.all()Retrieves all templates.promptlayer_client.templates.all()async_promptlayer_client.templates.all()
run()Executes a prompt template.promptlayer_client.run()async_promptlayer_client.run()
run_workflow()Executes a workflow.promptlayer_client.run_workflow()async_promptlayer_client.run_workflow()
track.metadata()Tracks metadata.promptlayer_client.track.metadata()async_promptlayer_client.track.metadata()
track.group()Tracks a group.promptlayer_client.track.group()async_promptlayer_client.track.group()
track.prompt()Tracks a prompt.promptlayer_client.track.prompt()async_promptlayer_client.track.prompt()
track.score()Tracks a score.promptlayer_client.track.score()async_promptlayer_client.track.score()
group.create()Creates a new group.promptlayer_client.group.create()async_promptlayer_client.group.create()
log_request()Logs a request.promptlayer_client.log_request()async_promptlayer_client.log_request()

Note: All asynchronous methods require an active event loop. Use them within an async function and run the function using asyncio.run() or another method suitable for managing event loops (e.g., await in Jupyter notebooks).
