What is LMQL?

LMQL is a programming language that lets you write code to interact with large language models like GPT in a more controlled way. It allows you to add constraints to AI responses, such as limiting length or ensuring specific formats, making outputs more reliable. This is great for developers and researchers who want to build AI applications without deep prompt engineering expertise.

Key Features of LMQL

  1. 1

    Nested Queries

    Enables modular and reusable prompt components for efficiency

  2. 2

    Constrained Generation

    Enforces output constraints like length and stop conditions

  3. 3

    Backend Portability

    Runs on multiple LLM backends with easy switching

  4. 4

    Python Integration

    Uses Python syntax for prompt construction and control flow

  5. 5

    Typed Variables

    Guarantees outputs are in specified formats like integers
