Multi-Provider AI: Why You Should Never Lock Into One LLM

The AI landscape changes monthly

GPT-4 was king last year. Claude 3.5 Sonnet took the crown this year. Gemini is catching up fast. If your app is hardcoded to one provider, you're one API change away from disaster.

The ruby_llm approach

The Rails AI Kit uses ruby_llm, which provides a unified interface across OpenAI, Anthropic, and Google Gemini. Switching models is a one-line change — no code rewrite needed.

Let your users choose

The kit's chat interface lets users select their preferred model per conversation. Some prefer GPT-4o for coding, Claude for writing, Gemini for research. Give them the choice and increase stickiness.

Cost optimization

Different models have different price points. Route simple queries to cheaper models and complex ones to premium models. The admin analytics show you exactly which models your users prefer and what they cost you.
