RWKV Runner
Free, open-source desktop app for running and fine-tuning RWKV RNN language models locally with effectively unbounded context.
RWKV Runner is a genuinely unusual free pick: an 8MB open-source desktop app that runs an attention-free RNN where you get effectively unlimited context and no KV-cache memory blowup. The RWKV project's Albatross path cites 7B fp16 at batch size 960 hitting 10,250+ tokens/sec on an RTX 5090, and RWKV-PEFT lets you fine-tune a 7B model on around 9GB of VRAM — neither is a spec you find in most local-LLM tools. If you want a local OpenAI-compatible endpoint and don't need GPT-grade breadth, this is a strong, no-cost choice. If you need a turnkey hosted service, a support contract, or a broad pre-trained model library, look at hosted API vendors or a wider local runtime instead.

Skip RWKV Runner if your existing work is already built around a different model family, since it only runs RWKV weights and will not load your existing models.
The project publishes RWKV Runner as a free, open-source desktop app under Apache 2.0 via the Linux Foundation AI project, so there is no software licence cost — your real spend is the GPU. Fine-tuning a 7B model is documented at around 9GB of VRAM, and the Albatross throughput figure is quoted on an RTX 5090, so budget for hardware rather than a subscription. That puts it well below metered cloud inference for high-volume long-context work.

About RWKV Runner
RWKV Runner is a free, open-source desktop GUI — the project lists it at 8MB — for running RWKV language models on your own hardware. RWKV itself is an attention-free RNN architecture from the RWKV project, a Linux Foundation AI project under Apache 2.0, that trains in parallel like a Transformer while using linear time and constant space: there is no KV-cache, so context length is effectively unbounded. The Runner gives you a point-and-click interface for inference, training, and fine-tuning, and exposes an OpenAI-compatible API so you can point existing tools at your local instance. It supports the RWKV-7 'Goose' reasoning models announced in May 2025, along with RWKV-7 GGUF and Ollama-format weights, and precision options including nf4, int8, and fp16. It runs cross-platform on Windows, Mac, and Linux. It fits developers who want free local inference they can ship commercially, researchers studying attention-free RNN architectures, and privacy-minded users who need long-context AI without sending data to a cloud. The trade-off versus the big hosted APIs is a smaller model zoo and a more hands-on, research-grade setup.
Behind the Verdict
RWKV Runner's case rests on the underlying architecture, not the GUI. RWKV is 100% attention-free and the project describes it as combining the best of RNN and Transformer: linear time, constant space, infinite ctxlen, and free text embedding. In practice that means conversation history and long documents do not blow up your VRAM the way a KV-cache does — you can keep a chatbot's transcript growing without re-architecting around a context ceiling. The Runner wraps that in a desktop GUI with inference, training, and fine-tuning tabs, plus an OpenAI-compatible API so existing apps can be pointed at your machine instead of a cloud provider. The engineering around it is real. Albatross is the project's efficiency-focused inference path (7B fp16 bsz960 = 10,250+ tps on a 5090). RWKV-PEFT handles fine-tuning and the project says 9GB of VRAM is enough to fine-tune a 7B model. RWKV-server adds WebGPU inference for NVIDIA, AMD, and Intel GPUs with nf4/int8/fp16 precision, which matters if you are not on CUDA. Weights ship as RWKV-7 GGUF and RWKV-7 Ollama-format files, and the project counts 800+ RWKV projects in its ecosystem. Where it falls down is breadth and support. You get the RWKV family and essentially nothing else: if your work depends on a different model family, this is the wrong tool. Setup leans on GitHub, Discord, and the RWKV wiki rather than a vendor help desk — and the wiki itself is marked by the project as AI-written, so treat it as a starting point, not an authority. Documentation pages were not reachable in this research pass, so we cannot characterise how good the API docs or onboarding guides are. There is a real learning curve if you are used to cloud APIs: you own uptime, hardware, and updates. Fine-tuning is viable on modest GPUs by the project's own numbers, but you still need a compatible GPU and patience for a research-grade toolchain. RWKV belongs to the Linux Foundation AI umbrella under Apache 2.0, which is the strongest signal here for commercial adoption — you are not betting on a startup's continued goodwill. Pair the Runner with the RWKV pip package for scripting, the mobile app for Android/iOS if you want it on a phone, and the Discord for the questions the wiki does not answer. Best fit: a developer with one decent GPU who wants free local inference with unbounded context and does not need a menu of model families. Worst fit: a team that needs someone to call when it breaks.

Real-world workflow fit
Concrete scenarios for the personas RWKV Runner actually fits — and what changes day-one when you adopt it.
Install RWKV Runner on a workstation with a compatible GPU, download RWKV-7 GGUF weights, load them in the desktop GUI, and start the OpenAI-compatible API on localhost.
Outcome: Your existing app keeps its OpenAI-style calls but now hits your own machine, with no per-token bill and no prompt data leaving your hardware.
Use the Runner's training and fine-tuning tabs with RWKV-PEFT to fine-tune a 7B model on a ~9GB VRAM GPU, then compare throughput on the Albatross inference path.
Outcome: A reproducible local pipeline for experimenting with RWKV-7 'Goose' weights without renting a cluster.
Load a long transcript or document set into a chatbot backed by the Runner's local OpenAI-compatible endpoint, relying on the constant-space design instead of a KV-cache.
Outcome: Conversation history grows without the memory blowup you would hit on a Transformer with a fixed context window.
Use Cases
- Run a 7B model locally and fine-tune it on a GPU with around 9GB VRAM via RWKV-PEFT

Models Under the Hood
as of 2026-10-17
Limitations
- RWKV Runner is an open-source desktop GUI that runs RWKV RNN models locally and exposes an OpenAI-compatible API; it is not a hosted inference service, so uptime, hardware, and updates are on you.
- It runs the RWKV family specifically — RWKV-7 'Goose' reasoning models plus RWKV-7 GGUF and Ollama-format weights — so if your work depends on a different model family, this is the wrong tool.
- Setup leans on the project's GitHub, Discord, and wiki rather than a vendor help desk, and the wiki is flagged by the project itself as AI-written.
- Documentation and changelog pages were not reachable in this research pass, so we cannot speak to how complete the API docs are or how frequently releases land.
- Fine-tuning is viable on modest GPUs (the project cites 9GB VRAM for a 7B model via RWKV-PEFT), but you still need a compatible GPU and the patience for a research-grade toolchain.

Where the pricing makes sense
The company stage and team size where RWKV Runner's pricing actually pencils out — and where peers do it cheaper.
The project publishes RWKV Runner as a free, open-source desktop app under Apache 2.0 via the Linux Foundation AI project, so there is no software licence cost — your real spend is the GPU. Fine-tuning a 7B model is documented at around 9GB of VRAM, and the Albatross throughput figure is quoted on an RTX 5090, so budget for hardware rather than a subscription. That puts it well below metered cloud inference for high-volume long-context work.
Setup time & first value
How long it actually takes to get something useful out of RWKV Runner — broken out by persona, not the marketing-page minute.
For a developer comfortable with Python environments and GPU drivers, expect roughly an hour to install the Runner, pick and download RWKV-7 GGUF or Ollama-format weights, and get the local API answering requests. Add more time if you are compiling RWKV-PEFT for fine-tuning or wiring up the WebGPU path on an AMD or Intel GPU. Non-technical users should budget a weekend to get comfortable.
Switching to or from RWKV Runner
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a hosted LLM API: repoint your OpenAI-style client at the Runner's local endpoint and swap the model name for an RWKV-7 GGUF weight.
- →From Ollama: keep your existing Ollama-format RWKV weights and load them through the Runner's desktop GUI.
- →From a plain Python script: use the RWKV pip package for the same models if you would rather script than click.
- ↗To hosted API vendors: swap your endpoint back and accept per-token metering in exchange for a broader model zoo.
- ↗To a wider local runtime: move to a tool with a larger pre-trained model library if you need families beyond RWKV.
