LLMCallStartingEvent

data class LLMCallStartingEvent(val runId: String, val callId: String, val prompt: Prompt, val model: ModelInfo, val tools: List<String>, val timestamp: Long = Clock.System.now().toEpochMilliseconds()) : DefinedFeatureEvent(source)

Represents an event indicating the start of a call to a Language Learning Model (LLM).

This event captures the details of the LLM interaction at the point of invocation, including the input prompt and any tools that will be used during the call. It extends the DefinedFeatureEvent class and serves as a specific type of event in a feature-driven framework.

Constructors

constructor(runId: String, callId: String, prompt: Prompt, model: String, tools: List<String>, eventId: String = LLMCallStartingEvent::class.simpleName!!, timestamp: Long = Clock.System.now().toEpochMilliseconds())

Properties

callId

val callId: String

A unique identifier associated with the specific LLM call grouping.

messageType

open override val messageType: FeatureMessage.Type

Specifies the type of the feature message for this event.

model

val model: ModelInfo

The model information including provider, model, and context details.

modelString

val ~~modelString~~: String

prompt

val prompt: Prompt

The input prompt encapsulated as a Prompt object. This represents the structured set of messages and configuration parameters sent to the LLM.

runId

val runId: String

A unique identifier associated with the specific run of the LLM call.

timestamp

open override val timestamp: Long
