Stars measure visibility, not whether either tool fits your constraints. ### Are LLM.swift and litgpt open source? Yes - both are open-source projects on GitHub (LLM.swift: MIT, litgpt: Apache-2.0). ### Where can I find alternatives to LLM.swift or litgpt? GraphCanon lists graph-backed alternatives at [LLM.swift alternatives](/tools/eastriverlee-llm-swift/alternatives) and [litgpt alternatives](/tools/lightning-ai-litgpt/alternatives) ([LLM.swift markdown twin](/tools/eastriverlee-llm-swift/alternatives.md), [litgpt markdown twin](/tools/lightning-ai-litgpt/alternatives.md)), 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](/compare/eastriverlee-llm-swift-vs-lightning-ai-litgpt.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, LLM.swift or litgpt? LLM.swift: Steady. litgpt: Active. 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 LLM.swift and litgpt? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [LLM.swift trust report](/tools/eastriverlee-llm-swift/trust); [litgpt trust report](/tools/lightning-ai-litgpt/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=eastriverlee-llm-swift`](/api/graphcanon/graph?tool=eastriverlee-llm-swift) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
