Runanywhere Sdks
On-device inference SDKs with hand-written GPU and NPU kernels from a Y Combinator-backed inference lab.
Pick RunAnywhere when latency lives on the device and you control the app code. The concrete draws are reproducible kernel benchmarks (658 tok/s decode and 6.6ms TTFT on M4 Max), full NPU execution on Qualcomm Hexagon since QHexRT went live in June 2026, and one C++ core behind six platform bindings so an Android and an iOS build behave the same. A solo developer porting his $2K MRR local-AI app from Android to iOS in six weeks using the SDK is the most concrete adoption signal here. If your stack is CUDA and NVIDIA or you want a button-click managed API, look elsewhere — every documented target is Apple or Qualcomm silicon.

Skip RunAnywhere if you're deploying on NVIDIA CUDA hardware, or if you want a finished no-code app rather than an SDK you compile into your own product.
QHexRT and MetalRT only accelerate Apple M-series and Qualcomm Hexagon silicon, so supporting a third chip family means funding or writing that engine work yourselves.
Pricing isn't visible from this run's sources, so compare RunAnywhere against what you'd otherwise spend building the same accelerated path: an in-house kernel team, or per-token cloud API spend on voice and vision traffic. The cost scales with how much of your inference you keep on-device versus hosted through Wally.

About Runanywhere Sdks
RunAnywhere is an inference lab that builds on-device AI infrastructure around hand-written GPU and NPU kernels instead of generic runtimes. Three pieces sit under the name: Wally, a hosted tier serving frontier-scale open models behind an OpenAI-compatible API, with requests leaving your machine only when you explicitly say so; the accelerated local engines MetalRT for Apple M-series GPUs and QHexRT for Qualcomm Hexagon NPUs; and open-source SDKs in Swift, Kotlin, React Native, Flutter, TypeScript, Web and Electron that all sit on one C++ core so behaviour doesn't drift between platforms. The published numbers are the pitch: 658 tok/s decode and 6.6ms time-to-first-token on an M4 Max with MetalRT, speech-to-speech at 1.68s end-to-end, and QHexRT running LLM, VLM, STT, TTS and embeddings entirely on Hexagon NPUs, with LFM 2.5 230M at 12,540 tok/s prefill since it went live in June 2026. In July 2026 PrismML Bonsai, a 27B 1-bit reasoning model, began running on-device across iOS, Android and macOS, described by the team as the first true 1-bit model running on an NPU. Company security posture is SOC 2 Type II with the audit in progress. This is engineering infrastructure you integrate into your own app, not a drop-in managed service, and the silicon targets are Apple and Qualcomm.
Behind the Verdict
The interesting thing about RunAnywhere is where it spends effort. Most on-device AI offerings are a runtime wrapper around someone else's kernels; this lab writes Metal and Hexagon kernels by hand and then publishes the hardware and method behind every number, which is why the benchmarks are quotable rather than decorative. On an M4 Max, MetalRT reports 658 tok/s decode and 6.6ms time-to-first-token; speech-to-speech lands at 1.68s end-to-end, measured 1.52x faster than mlx-audio. QHexRT, live since June 2026, runs LLM, VLM, STT, TTS and embeddings 100% on Qualcomm Hexagon NPUs, with LFM 2.5 230M at 12,540 tok/s prefill. Vision language models arrived in March 2026 at 279 tok/s vision decode. The architectural decision that matters most for teams is probably the least glamorous: one C++ core, runanywhere-core, with thin bindings for Swift, Kotlin, React Native, Flutter, TypeScript and C++. Six bindings, one behaviour contract, so your second platform doesn't quietly diverge from your first. That, plus cross-platform reach across iOS, Android, macOS, Windows, Linux, web and embedded, is what makes a two-platform launch tractable for a small team — the developer who moved Android to iOS in six weeks is a believable data point for exactly this reason. The July 2026 milestone is worth flagging separately: PrismML Bonsai, a 27B 1-bit reasoning model, now runs on-device across iOS, Android and macOS, including what the team describes as the first true 1-bit model running on any NPU. A 27B model on a phone changes what an offline assistant can be, and it moves the conversation from small-model compromises to genuine capability. Where it fits: mobile and edge teams where voice or vision latency is the product experience, privacy-first apps that need inference with no cloud round-trip, and performance engineers who want to reproduce the numbers themselves. Where it doesn't: if your deployment target is NVIDIA, or your team wants a no-code tool, or your project leans on a large tutorial ecosystem and years of forum answers, the hand-tuned-kernel trade goes the wrong way. Accelerated local inference is also tied to specific silicon — MetalRT is Apple M-series, QHexRT is Qualcomm Hexagon — and the headline figures are reported for named reference hardware, so your results on a mid-range device will differ. Hosted frontier-scale models via Wally leave your machine only when you opt in; the documentation also notes that AI-generated assistant responses can be wrong.

Real-world workflow fit
Concrete scenarios for the personas Runanywhere Sdks actually fits — and what changes day-one when you adopt it.
Add the Swift or Kotlin SDK to an existing app, pull a model down for on-device STT, LLM, and TTS, and benchmark speech-to-speech end-to-end against the 1.68s reference figure on your own target device.
Outcome: A voice loop that runs with no network round-trip, with a measured latency number you can put in front of stakeholders.
Keep the existing runanywhere-core integration and swap in the Swift binding instead of rewriting the inference path, then validate that both builds produce the same model behaviour through the shared core.
Outcome: A second platform in weeks rather than a quarter — the same shape as the solo developer who shipped his Android app to iOS in six weeks.
Run a local VLM on frames as they arrive, filter to the frames that matter, and route only those to a cloud VLM through the OpenAI-compatible Wally API — which only leaves the machine when you opt in.
Outcome: Lower bandwidth and a smaller data-exposure surface, with cloud inference reserved for the frames that actually need frontier-scale reasoning.
Use Cases
- Run LLM inference fully on-device on Apple Silicon with sub-7ms time-to-first-token.
- Ship a vision agent that processes live video locally and sends only relevant frames to a cloud VLM.
- Build an offline Android assistant that listens, reasons, and speaks back with no network round-trip.
- Ship one on-device AI codebase across iOS, Android, and web via a single SDK binding.
- Assemble a sub-200ms voice RAG pipeline that stays entirely on-device.
- Run a 27B 1-bit reasoning model on a phone with PrismML Bonsai.
- Point an OpenAI-compatible client at a hosted frontier-scale open model through Wally.
Models Under the Hood
as of 2026-09-22
Limitations
- Accelerated local inference is tied to specific silicon: MetalRT targets Apple silicon (M-series) and QHexRT targets Qualcomm Hexagon NPUs.
- Published performance figures are reported for named reference hardware — MetalRT results are quoted for a single M4 Max, QHexRT results for Hexagon — so results on other devices will differ.
- This is engineering infrastructure you integrate into your app code; adapters are documented for OpenAI-compatible clients such as opencode, but there is no library of off-the-shelf app connectors to wire up.
- The documentation notes that AI-generated assistant responses may contain mistakes, and SOC 2 Type II is listed as an audit in progress rather than complete.

Where the pricing makes sense
The company stage and team size where Runanywhere Sdks's pricing actually pencils out — and where peers do it cheaper.
Pricing isn't visible from this run's sources, so compare RunAnywhere against what you'd otherwise spend building the same accelerated path: an in-house kernel team, or per-token cloud API spend on voice and vision traffic. The cost scales with how much of your inference you keep on-device versus hosted through Wally.
Setup time & first value
How long it actually takes to get something useful out of Runanywhere Sdks — broken out by persona, not the marketing-page minute.
Developers on Apple silicon can get a first model running through the docs quickstart in an afternoon, since MetalRT is the accelerated path there. Android teams should budget extra time for a Hexagon NPU validation pass on their own device targets. Reaching a first hosted Wally response is the shortest path — install, sign in, paste the first API request curl.
Switching to or from Runanywhere Sdks
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a cloud-only LLM API: point an OpenAI-compatible client at Wally first, then move the latency-critical paths onto the on-device SDKs.
- →From llama.cpp or MLX: keep your model choices and swap the runtime for the MetalRT or QHexRT accelerated engine, then re-run your own benchmarks.
- →From a self-built Metal kernel layer: replace hand-maintained kernels with the SDK bindings on runanywhere-core and keep one behaviour contract across platforms.
- →From an Android-only on-device stack: reuse the existing core integration and add the Swift or Flutter binding for iOS rather than maintaining a second inference path.
- ↗To llama.cpp or MLX: you regain a wider tutorial and community ecosystem, but you give up the Hexagon NPU engine and the single cross-platform core.
- ↗To a cloud LLM API: simplest integration path, but every voice or vision round-trip pays network latency and exposes data you could have kept on-device.
- ↗To NVIDIA CUDA tooling: required if your deployment hardware moves off Apple and Qualcomm silicon, since MetalRT and QHexRT target those chips only.

Featured Head-to-Head Comparisons
Runanywhere Sdks vs Spider Cloud
These tools serve completely different needs. Choose RunAnywhere if you need to run AI models on-device with low latency and privacy; choose Spider Cloud if you need to fetch and structure live web data for AI agents or RAG. They complement each other but are not direct competitors.
Runanywhere Sdks vs Temporal Ai
Temporal and RunAnywhere solve fundamentally different problems. Temporal is the no-compromise platform for building fault-tolerant, long-running AI agent workflows with full state persistence, making it ideal for teams that need reliability at scale. RunAnywhere excels at deploying AI models on-device with sub-10ms latency, perfect for mobile and edge apps prioritizing privacy and speed. Choose Temporal if you need orchestration and reliability; choose RunAnywhere if you need local inference with cross-platform SDKs.
Runanywhere Sdks vs Voyage Ai
If you need high-accuracy retrieval embeddings for enterprise RAG (e.g., finance, legal), Voyage AI is the specialist—its domain-specific models and low-dimensional vectors cut storage costs. But if you're building mobile or edge apps that demand sub-10ms on-device inference with full privacy, RunAnywhere's MetalRT and QHexRT engines are unmatched. The two tools solve different problems: one optimizes cloud retrieval, the other local execution. Choose based on your deployment target.
