LLM Gateways & APIs

14 tools · 2 subcategories

The connectivity layer between applications and models. Hosted APIs like the OpenAI, Anthropic, and Gemini APIs give direct access to frontier models; LLM gateways and proxies like OpenRouter, LiteLLM, and PortKey add multi-provider routing, caching, cost control, and fallbacks on top. Pick a gateway when you want one bill and easy model switching; go direct when you need day-one access to provider features.
