Comparison
whichllm vs ai-gateway
Verdict
Pick whichllm if whichllm is designed to help users identify and benchmark local large language models that perform well on their specific hardware configuration via real-time benchmarks; pick ai-gateway if ai-gateway from Ferro Labs supports over 30 LLMs with integrated caching, guardrails, A/B testing, and cost controls, making it ideal for managing multiple language models in a production environment.

Shared compatibility
- Python · whichllm: Python runtime · ai-gateway: Python runtime
Choose whichllm if…
- whichllm is primarily Python; ai-gateway is Go.
- License: whichllm is MIT, ai-gateway is Apache-2.0.
- Tags unique to whichllm: ai, apple-silicon, benchmarks, cli.
- Also covers Evaluation & Observability.
- When you need to quickly discover which locally available LLM runs most efficiently on your Apple Silicon or GPU infrastructure using Python scripts
When NOT to use whichllm
- In scenarios where extensive customization of benchmarking criteria beyond what this tool offers is required
- When you are working in a non-Python environment and prefer not to introduce Python scripts into your workflow
Choose ai-gateway if…
- ai-gateway is primarily Go; whichllm is Python.
- License: ai-gateway is Apache-2.0, whichllm is MIT.
- Tags unique to ai-gateway: ai-gateway, litellm, llm-cost, llm-proxy.
- 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
