Choose ai-gateway if…
- License: ai-gateway is Apache-2.0, oss-llmops-stack is MIT.
- Tags unique to ai-gateway: litellm, llm-cost, llm-proxy, openai-compatible.
- Also covers Model Training.
- When you need to integrate more than 30 different LLM services including OpenAI and Anthropic
When NOT to use ai-gateway
- If your project only involves one or two LLMs which does not necessitate the gateway's broad compatibility features
- For small-scale projects that do not require comprehensive cost analysis tools
- When custom integration for specific guardrails is required, as ai-gateway offers generalized settings
Choose oss-llmops-stack if…
- License: oss-llmops-stack is MIT, ai-gateway is Apache-2.0.
- Requirements: Ensure your environment supports both LiteLLM and Langfuse functionalities for seamless operation of the OSS LLMOps Stack.; Consider server capacity to handle the additional load introduced by using this stack for API unification and observability services..
- Tags unique to oss-llmops-stack: llm-evaluation, open-source, prompt-management.
- Also covers Evaluation & Observability.
- When you need to unify Multiple Large Language Model (LLM) APIs using LiteLLM's API mediation capabilities for efficient routing, cost control, and high-availability support.
When NOT to use oss-llmops-stack
- If your operational requirements are simple and you do not need comprehensive observability metrics or advanced LLM API unification capabilities provided by the stack.
- In scenarios where you prefer a proprietary software solution over an open-source tool for security, support, or compliance reasons.
