Tokz Labs builds small, fast models for AI agents. The Decisions API answers typed questions about text with the open OpenDecision models, on one API key and one prepaid balance. Every account starts with $5 of free credit.

What it does

Agents spend LLM calls on small classification jobs: which queue a ticket goes to, whether a message is urgent, which tags apply, how severe something is. POST /v1/decide answers those without a generation. You put the labels in the request, and no training run is needed. When you want a model trained on your own text, Fine Tune builds one.

Four question types

choice, multilabel, bool and score, up to 16 questions per request.

A probability for every option

Not just a label: the distribution over options, so you can threshold, abstain or escalate.

Open weights

The hosted models are the same Apache-2.0 OpenDecision weights published on Hugging Face. Run them yourself if you prefer.

Not stored

Text sent to /decide is read by the model and not stored or logged. Only counters are kept.
