## Choose when

### Choose FLsystem-paper if…

- Tags unique to FLsystem-paper: awesome-list, federated-learning, machine-learning, mlsys.
- Also covers Model Training.
- Leaner open-issue backlog (1).

### Choose litellm if…

- Pricing: While the core functionality is provided free, specific extended features might require a paid plan..
- Requirements: Requires Docker.
- Tags unique to litellm: ai-gateway, azure-openai, bedrock, llm.
- 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 FLsystem-paper

- Last GitHub push was 886 days ago (dormant maintenance, Feb 7, 2024). Validate activity before betting a new project on FLsystem-paper.
- 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.

## When NOT to use litellm

- If your project only requires interaction with a single LLM API and basic functionalities, litellm may be overkill.
