LlamaFactory: Unified Efficient Fine-Tuning of 100+ LLMs & VLMs. semantic-router: System level intelligent runtime for Mixture-of-Models across edge, data center and cloud. See the comparison table for live GitHub stats and shared categories. ### When should I choose LlamaFactory over semantic-router? Choose LlamaFactory over semantic-router when LlamaFactory is primarily Python; semantic-router is Go; Tags unique to LlamaFactory: agent, ai, deepseek, gemma; When you need to fine-tune over 100 different LLMs or VLMs with efficient methods like LoRA or QLoRA. ### When should I choose semantic-router over LlamaFactory? Choose semantic-router over LlamaFactory when semantic-router is primarily Go; LlamaFactory is Python; Tags unique to semantic-router: ai-gateway, bert-classification, golang, huggingface-candle; Also covers Inference & Serving. ### When should I avoid LlamaFactory? When you are looking to fine-tune less popular or niche models that are not supported within the 100+ models covered by LlamaFactory. If your project specifically requires custom fine-tuning methods not available in this repository, such as certain versions of PEFT (Parameter Efficient Fine-Tuning) techniques excluding LoRA and QLoa ### When should I avoid semantic-router? Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic. LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ### Is LlamaFactory or semantic-router more popular on GitHub? LlamaFactory has more GitHub stars (73,157 vs 4,916). Stars measure visibility, not whether either tool fits your constraints. ### Are LlamaFactory and semantic-router open source? Yes - both are open-source projects on GitHub (LlamaFactory: Apache-2.0, semantic-router: Apache-2.0). ### Where can I find alternatives to LlamaFactory or semantic-router? GraphCanon lists graph-backed alternatives at [LlamaFactory alternatives](/tools/hiyouga-llamafactory/alternatives) and [semantic-router alternatives](/tools/vllm-project-semantic-router/alternatives) ([LlamaFactory markdown twin](/tools/hiyouga-llamafactory/alternatives.md), [semantic-router markdown twin](/tools/vllm-project-semantic-router/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/hiyouga-llamafactory-vs-vllm-project-semantic-router.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, LlamaFactory or semantic-router? LlamaFactory: Very active. semantic-router: Very 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 LlamaFactory and semantic-router? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [LlamaFactory trust report](/tools/hiyouga-llamafactory/trust); [semantic-router trust report](/tools/vllm-project-semantic-router/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=hiyouga-llamafactory`](/api/graphcanon/graph?tool=hiyouga-llamafactory) - 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/_
