Shared compatibility

  • Python · lmql: Python runtime · lagent: Python runtime

Choose lmql if…

  • Tags unique to lmql: chatgpt, huggingface, language-model, programming-language.
  • When needing precise control over language model output through programmable constraints
  • More GitHub stars (4.2k vs 2.3k) - visibility, not fit.

When NOT to use lmql

  • For general-purpose coding without leveraging specific LLM functionalities
  • If the project does not benefit from constraint-guided interactions with language models

Choose lagent if…

  • Pricing: Available freely due to its open-source nature, but customization or enterprise support might involve additional costs..
  • Tags unique to lagent: agent, gpt, llm, transformers.
  • Also covers AI Agents.
  • When you need a streamlined approach to develop LLM-based agents with minimal overhead, lagent can be particularly advantageous due to its lightweight design.

When NOT to use lagent

  • Avoid using lagent if your project necessitates integration with a broader set of tools that are not natively supported by this framework, as it offers limited out-of-the-box extensibility.
  • Steer clear if you need robust scalability features right from the start. While lightweight, lagent may require additional custom work to handle more demanding scaling requirements.
