Firebase Vertex AI integration enabling agent-framework LLM prompts with preconfigured Gemini model definitions, streaming responses, and simple executor adapters for easy backend connection.
Firebase Vertex AI integration for the Koog Agent Framework.
Add to your libs.versions.toml:
[versions]
koog-firebase = "0.5.0"
[libraries]
koog-firebase = { module = "dev.ynagai.koog:koog-firebase", version.ref = "koog-firebase" }
Then in your build.gradle.kts:
dependencies {
implementation(libs.koog.firebase)
}
dependencies {
implementation("dev.ynagai.koog:koog-firebase:0.5.0")
}
import ai.koog.agents.core.agent.AIAgent
import dev.ynagai.koog.firebase.FirebaseModels
import dev.ynagai.koog.firebase.simpleFirebaseExecutor
val agent = AIAgent(
promptExecutor = simpleFirebaseExecutor(),
systemPrompt = "You are a helpful assistant.",
llmModel = FirebaseModels.Gemini2_5Flash
)
val result = agent.run("Hello!")
import dev.ynagai.firebase.Firebase
import dev.ynagai.firebase.ai.GenerativeBackend
import dev.ynagai.koog.firebase.simpleFirebaseExecutor
// Use Vertex AI backend
val executor = simpleFirebaseExecutor(
app = Firebase.app,
backend = GenerativeBackend.vertexAI()
)
