Choose uqlm if…
- Tags unique to uqlm: ai safety, ai-evaluation, confidence-estimation, hallucination-detection.
- Also covers Evaluation & Observability.
- When precise estimation of confidence scores is needed to ensure reliability in language model predictions.
When NOT to use uqlm
- If working exclusively with non-language-based machine learning models, as uqlm focuses on text outputs from LLMs.
- When simple plug-and-play performance metrics suffice; uqlm requires a more intricate setup for uncertainty quantification and confidence estimation.
Choose lmql if…
- Tags unique to lmql: chatgpt, huggingface, language-model, programming-language.
- Also covers LLM Frameworks.
- When needing precise control over language model output through programmable constraints
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

- Is uqlm or lmql more popular on GitHub?
- lmql has more GitHub stars (4,203 vs 1,188). Stars measure visibility, not whether either tool fits your constraints.
- Are uqlm and lmql open source?
- Yes - both are open-source projects on GitHub (uqlm: Apache-2.0, lmql: Apache-2.0).
- Where can I find alternatives to uqlm or lmql?
- GraphCanon lists graph-backed alternatives at uqlm alternatives and lmql alternatives (uqlm markdown twin, lmql markdown twin), ranked by typed relationship edges rather than popularity votes.
- Is there a machine-readable version of this comparison?
- Yes. The markdown twin at this comparison mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers.
- Which is better maintained, uqlm or lmql?
- uqlm: Very active. lmql: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance.
- Where are the full trust reports for uqlm and lmql?
- GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: uqlm trust report; lmql trust report.
