SpringAiLlmService

data class SpringAiLlmService constructor(val name: String, val provider: String, val chatModel: <Error class: unknown class>, val optionsConverter: <Error class: unknown class><out <Error class: unknown class>> = DefaultOptionsConverter, val knowledgeCutoffDate: LocalDate? = null, val promptContributors: List<<Error class: unknown class>> = buildList { knowledgeCutoffDate?.let { add(KnowledgeCutoffDate(it)) } }, val pricingModel: <Error class: unknown class>? = null) : LlmService<SpringAiLlmService>

Spring AI implementation that provides decoupled LLM operations.

Wraps a Spring AI ChatModel and provides the ability to create LlmMessageSender instances for making LLM calls without tight coupling to Spring AI throughout the codebase.

This class is the recommended replacement for the deprecated com.embabel.common.ai.model.Llm class.

Parameters

name

Name of the LLM

provider

Name of the provider (e.g., "OpenAI", "Anthropic")

chatModel

The Spring AI ChatModel to use for LLM calls

optionsConverter

Function to convert LlmOptions to Spring AI ChatOptions

knowledgeCutoffDate

Model's knowledge cutoff date, if known

promptContributors

List of prompt contributors for this model. Knowledge cutoff is automatically included if knowledgeCutoffDate is set.

pricingModel

Pricing model for this LLM, if known
