What is PromptL?

PromptL offers a common, easy-to-use syntax for defining dynamic prompts for LLMs. It is a simple, yet powerful language that allows you to define prompts in a human-readable format, while still being able to leverage the full power of LLMs.

chain = promptl.chains.create(
    prompt=prompt,
    parameters={
        "context": "PromptL is a templating language specifically designed for LLM prompting.",
        "question": "What is PromptL?",
    },
)
conversation = chain.step()
conversation = chain.step("Reasoning...")  # LLM response
