Tokenless

The router that cuts your inference bill in half.

A drop-in replacement for your API calls — always routed to the right model.

Same quality, half the cost.

Most calls don’t need a frontier model. Tokenless fans out your request to a group of models and watches them think. Once a model is clearly on track, we select it and cancel the other models, and you only pay for what you need.

We expose an OpenAI and Anthropic compatible endpoint. Point your models at us and get started today!

Key points

  • Drop-in replacement for OpenAI and Anthropic API calls, automatically routing to the cheapest model that can do the job.
  • Parallel request execution: sends to multiple models, then cancels all but the one that starts producing the correct answer.
  • Benchmarks show up to 57% cost reduction on coding tasks while matching the quality of frontier models like Opus 4.8.
  • Built by AI researchers from Google DeepMind, Princeton, and UC Berkeley; backed by Y Combinator.
