Introduction

The RunAnywhere Kotlin SDK runs language, speech, and vision models on the device. Prompts, audio, and images stay on the phone, and everything keeps working with no network. On Snapdragon hardware it runs on the Hexagon NPU.

import com.runanywhere.sdk.public.RunAnywhere
import com.runanywhere.sdk.public.api.*

RunAnywhere.initialize(apiKey = "", baseUrl = "")

val result = RunAnywhere.llm.generate("Name three colours")
println(result.text)

The namespaces are Kotlin extension properties, declared in com.runanywhere.sdk.public.api. Without the wildcard import above, RunAnywhere.llm does not resolve and nothing on this page compiles.

Requirements

Item	Minimum
Android	API 24 (7.0), compile and target SDK 37
JDK	17
Kotlin	2.4
Device	ARM64. The NPU backend does not exist on x86_64 emulators.

This is an Android library, not Kotlin Multiplatform.

The namespaces

Namespace	What it does
`llm`	Text generation, streaming, tools, structured output
`vlm`	Image plus prompt
`stt`	Speech to text
`tts`	Text to speech
`vad`	Voice activity detection
`voice`	A full spoken conversation
`rag`	Retrieval over your own documents
`models`	Registry, download, load, unload
`embeddings`	Text vectors
`rerank`	Reorder results against a query
`lora`	Adapters on the loaded base model
`images`	Image generation
`diarization`	Who spoke when
`segmentation`	Labelled regions in an image

Suspending functions where Swift is async, and Flow where Swift returns a stream. If you know one SDK, the other reads the same.

The flat verbs from earlier releases (RunAnywhere.generate, RunAnywhere.loadModel, and the rest) are deprecated in favour of these namespaces and will be removed.

Artifacts

Artifact	Version	Role
`runanywhere-sdk`	0.20.24	Core SDK and commons
`runanywhere-llamacpp`	0.20.24	LLM and VLM on GGUF
`runanywhere-onnx`	0.20.24	STT, TTS, VAD, embeddings
`runanywhere-qhexrt-android`	0.20.19	Qualcomm Hexagon NPU, arm64 only

QHexRT carries its own version. It stopped being published to Maven Central after 0.20.19 and cannot advance there, so it does not move with the other three.
