Every frontier model, one endpoint

GPT-6 Astra, Claude Opus 5.5, Claude Fable 5.1, Gemini 3.8 and more — one key, one wallet.

TokenRex gives you the full frontier catalog from OpenAI, Anthropic and Google behind a single account. Switch models by changing one string — no new SDK, no new key, no new billing account. Every model is charged at its live market price, and you always choose the model yourself: TokenRex never silently substitutes another one.

Frequently asked questions

How many models are available?

The full catalog is listed on the Models & Pricing page with live prices — new models are added as providers release them.
