Choose litellm if…
- litellm is primarily Python; semantic-router is Go.
- License: litellm is Other, semantic-router is Apache-2.0.
- Pricing: While the core functionality is provided free, specific extended features might require a paid plan..
- Requirements: Requires Docker.
- Tags unique to litellm: azure-openai, bedrock, openai, vertex-ai.
- litellm ships Docker support for self-hosted deployment.
- When you need to integrate multiple LLM (Language Learning Modelling) APIs into your application across different providers like Bedrock, Azure, OpenAI, VertexAI, Cohere, Anthropic, Sagemaker, Hugging
When NOT to use litellm
- If your project only requires interaction with a single LLM API and basic functionalities, litellm may be overkill.
Choose semantic-router if…
- semantic-router is primarily Go; litellm is Python.
- License: semantic-router is Apache-2.0, litellm is Other.
- Tags unique to semantic-router: bert-classification, fine-tuning, golang, huggingface-candle.
- Also covers Model Training.
When NOT to use 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.
