Promptlayer Tutorial

Promptlayer is a platform for prompt engineers. Log OpenAI requests. Search usage history. Track performance. Visually manage prompt templates.

Use Promptlayer to log requests across all LLM Providers (OpenAI, Azure, Anthropic, Cohere, Replicate, PaLM)​

liteLLM provides callbacks, making it easy for you to log data depending on the status of your responses.

Using Callbacks​

Get your PromptLayer API Key from https://promptlayer.com/

Use just 2 lines of code, to instantly log your responses across all providers with promptlayer:

litellm.success_callback = ["promptlayer"]

Complete code

from litellm import completion

## set env variables
os.environ["PROMPTLAYER_API_KEY"] = "your-promptlayer-key"

os.environ["OPENAI_API_KEY"], os.environ["COHERE_API_KEY"] = "", ""

# set callbacks
litellm.success_callback = ["promptlayer"]

#openai call
response = completion(model="gpt-3.5-turbo", messages=[{"role": "user", "content": "Hi 👋 - i'm openai"}])

#cohere call
response = completion(model="command-nightly", messages=[{"role": "user", "content": "Hi 👋 - i'm cohere"}])

Logging Metadata​

You can also log completion call metadata to Promptlayer.

You can add metadata to a completion call through the metadata param: 

completion(model,messages, metadata={"model": "ai21"})

Complete Code

from litellm import completion

## set env variables
os.environ["PROMPTLAYER_API_KEY"] = "your-promptlayer-key"

os.environ["OPENAI_API_KEY"], os.environ["COHERE_API_KEY"] = "", ""

# set callbacks
litellm.success_callback = ["promptlayer"]

#openai call - log llm provider is openai
response = completion(model="gpt-3.5-turbo", messages=[{"role": "user", "content": "Hi 👋 - i'm openai"}], metadata={"provider": "openai"})

#cohere call - log llm provider is cohere
response = completion(model="command-nightly", messages=[{"role": "user", "content": "Hi 👋 - i'm cohere"}], metadata={"provider": "cohere"})
