Quick take
Cloudflare's larger decision model for classifying information and choosing an action without generating a chat response.
This is not a chatbot and does not explain its decisions in prose. Test probability thresholds on your own examples. Hosted requests can truncate long state, and self-hosted limits depend on configuration.
TypeSafe AI's first System One model for fast, typed choices, scores, and probabilities that software can use directly.
Jev is intentionally literal and does not generate explanations or prose. TypeSafe documents weaknesses in arithmetic, counting, date comparison, indirection, noisy context, and adversarial instructions; keep deterministic logic in code and test every production decision boundary.
Compare the published facts
Values use each provider's own published units and limits. A blank means the provider did not publish a directly comparable value in the sources reviewed.
| AI decision models | Clef | Jev 1.13 |
|---|---|---|
| Input priceCurrent provider price for the text or structured state submitted to the model, including whether decision outputs are billed. | $0.24 / 1M input tokens | $0.042 / 1M input tokens; output free |
| Input capacityMaximum documented state and question capacity for one request. | 65,536 tokens; up to 64 questions per request | 64K tokens total; state plus longest question up to 32K |
| Decision typesThe bounded question forms the model can answer, such as choices, scores, or probabilities. | Choice, Score, and Noul probability questions | Choice, Score, and Noul probability questions |
| Output contractHow the response is constrained for direct use by application code. | Typed JSON decisions defined before inference | Typed JSON decisions defined before inference |
| UncertaintyWhether the endpoint exposes probabilities, confidence, or another calibrated signal. | Probability distributions; Choice and Score also include confidence | Probability distributions; Choice and Score also include confidence |
| Where to use itCurrent API, SDK, playground, and access-stage information. | Workers AI API and self-hosted weights | Early-access API and Playground; Python and JavaScript SDKs |
How to choose
Start with the job you need to complete, then validate cost, access, and policy details on your exact provider route.
Cloudflare says Workers AI customer content is not used for training or service improvement without explicit consent. Connected storage services can retain content. Self-hosted deployments follow your own storage and access controls.
Provider and API links
TypeSafe says it does not train or fine-tune on customer inputs. Its privacy policy does not promise a fixed zero-retention period and says services are hosted in the United States, so sensitive workloads should confirm contractual retention and processing terms.
