Experiential Labs

An open-source gateway with per-model provider waterfalls.

Experiential Labs fronts hosted providers, your own provider keys, and platform-funded credits behind one OpenAI-compatible API. Every model slug resolves through a provider waterfall that fails over between rungs, and its Responses API supports chained continuations. It lists bare slugs (qwen3.8-27b, gpt-5.5), which the site aligns to canonical ids using the maker behind each slug. Some slugs stay locked until the account buys credits.

What Experiential Labs carries

A gateway with 2,000 models is not necessarily a gateway with 2,000 chat models.

Not exclusive

209 of these models are on other gateways too

Anything in this list can be served from somewhere other than Experiential Labs without changing the model id your application sends.
