About ReLLM
ReLLM is a Python library that constrains language model completions to produce exact structured output, such as JSON or other formal grammars. It works by filtering the model's token probabilities at each step to only allow tokens that conform to a user-defined structure.
Best for
Developers who need deterministic, structured outputs from any language model
Use cases
- Generating valid JSON objects from free-form LLM responses
- Enforcing a specific schema for data extraction tasks
- Building reliable pipelines that require parseable outputs
Notes
513 stars on GitHub. Last updated 2023-08-10. Licensed MIT.
Pros
- Lightweight and model-agnostic, works with any completion API
- Open source with a simple Python interface
- Guarantees structural validity without post-processing
Cons
- Limited to exact structure constraints, not suitable for fuzzy or probabilistic outputs
- May slow down generation due to per-token filtering
- Community-maintained with no official support or extensive documentation
