Keep one API.
Claude, GPT, Gemini, DeepSeek and 600+ models behind one OpenAI-compatible endpoint. Switch providers without rewriting your app, see the price before production traffic, and keep a fallback ready when a model fails.

The integration tax
Your product should not break because the model market changed.
Provider-specific code, scattered keys and surprise bills turn every new model into another migration. CheaperLLM turns model choice into configuration.
Do not let one provider own your uptime
Move traffic to another model or provider without shipping a new authentication and billing integration.
Know the rate before the request
Compare model prices, use free routes for prototypes, and keep paid usage on one balance and one statement.
Best fit: prototypes, agents, SaaS features and teams that expect to switch models.
