Jev 1.14

jev-1.14

Jev 1.14 is TypeSafe's System One model for fast, structured decision-making in software. It evaluates text and application state against developer-defined questions, returning choices, yes/no probabilities, and scores that applications can use directly. Built for classification, routing, and automated workflows, it helps developers turn natural-language judgments into actionable outputs and supports evaluating multiple questions in parallel within a single request.

Jev 1.14 — Model Highlights

Verified strengths and model characteristics.

Typed Probabilistic Decisions

Returns choices, rubric scores and yes/no probabilities for focused judgments that application code can combine.

Parallel State Evaluation

Evaluates independent questions against shared context in parallel, reducing repeated processing in decision workflows.

Experimental Visual Grounding

Adds a Box question type that locates one image target with normalized coordinates and confidence; image features remain experimental.

Jev 1.14 — Use Cases

Practical workloads supported by official model information.

Support Intent Triage

Classify a support request, assess urgency and route it to a handler or reviewer using application-defined thresholds.

Retrieval Passage Scoring

Score retrieved passages for relevance before selecting evidence for a separate answer-generating model.

Image Crop Prototyping

Prototype semantic image crops by checking target presence and locating it with Box; review results before production use.

Jev 1.14 — FAQs

Model selection, limitations, pricing and TokenHub integration.

What Is Jev 1.14?+

Jev 1.14 is TypeSafe AI’s System One decision model update, released as jev-1.14.0 through jev-preview. It produces typed judgments for software.

When Should I Choose Jev 1.14?+

Choose it for focused routing, classification and scoring with predefined answers. Use a generative model for prose, code or extended reasoning explanations.

Does Calibration Guarantee Correct Answers?+

No. Calibration describes groups of predictions, not guaranteed correctness for one decision. Validate thresholds on representative data, including difficult and non-English inputs.

What Are Jev 1.14’s Experimental Limits?+

Images and Box are experimental. Box returns coordinates even when the target is absent. Default context is 64K per request and 32K per question; opt-in 262K context is slower and less accurate.

How Do I Use Jev 1.14 On TokenHub?+

If a route is available, follow TokenHub’s exact model ID and decision-request example. Confirm endpoint, question types and experimental-header support; do not assume standard chat request semantics.

How Is Jev 1.14 Priced?+

TypeSafe lists $0.042 per million input tokens and no output-token charge. Check TokenHub’s current route pricing and availability separately.
