Isoquant

A small curated catalog with zero-data-retention routing.

Isoquant serves two frontier models (DeepSeek V4.1 Flash and GLM-5.3 Flash) behind an OpenAI-compatible chat API, with optional zero-data-retention routing and reasoning traces on both models. Its bare ids stand as their own catalog rows, and its prices are quoted in nano-USD per token. The model list stays empty until FreeRouter's daily crawl records an Isoquant key.

3 models on Isoquant

The 3 most widely available are shown; the rest are searchable in the full model list. "Id on this gateway" is what Isoquant calls the model — where it differs from the canonical id, that difference is what a router has to translate.

What Isoquant carries

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