Class TypeSafeDecisionModel

java.lang.Object

dev.langchain4j.model.typesafe.TypeSafeDecisionModel

All Implemented Interfaces:

DecisionModel

@Experimental
public class TypeSafeDecisionModel
extends Object
implements DecisionModel

A DecisionModel backed by the TypeSafe System One API (POST /v1/systemone), which serves decision models such as Jev.

Other servers that implement the same API (for example OpenRouter, or self-hosted open models) can be used by setting TypeSafeDecisionModel.TypeSafeDecisionModelBuilder.baseUrl(String).

DecisionModel model = TypeSafeDecisionModel.builder()
        .apiKey(System.getenv("TYPESAFE_API_KEY"))
        .modelName("jev-latest")
        .build();

Since:

1.21.0

builder

public static TypeSafeDecisionModel.TypeSafeDecisionModelBuilder builder()

doDecide

public DecisionResponse doDecide(DecisionRequest request)

Description copied from interface: DecisionModel

The provider hook behind DecisionModel.decide(DecisionRequest).

Specified by:

doDecide in interface DecisionModel

Parameters:

request - the request, with the default parameters already applied.

Returns:

one answer per question, keyed by question name.

doDecideAsync

public CompletableFuture<DecisionResponse> doDecideAsync(DecisionRequest request)

Description copied from interface: DecisionModel

The provider hook behind DecisionModel.decideAsync(DecisionRequest). The default returns a failed future: a model that is not genuinely asynchronous does not pretend to be.

Specified by:

doDecideAsync in interface DecisionModel

Parameters:

request - the request, with the default parameters already applied.

Returns:

a CompletableFuture of the answers, keyed by question name.

defaultRequestParameters

public DecisionRequestParameters defaultRequestParameters()

Description copied from interface: DecisionModel

The model's default per-call parameters, applied to every request and overridden by any parameters set on the request itself. The default is DecisionRequestParameters.EMPTY.

Specified by:

defaultRequestParameters in interface DecisionModel

listeners

public List<DecisionModelListener> listeners()

Description copied from interface: DecisionModel

The listeners notified of every request, response and error of this model.

Specified by:

listeners in interface DecisionModel

provider

public ModelProvider provider()

Description copied from interface: DecisionModel

The provider of this model.

Specified by:

provider in interface DecisionModel
