📖 Docs | 📺 Demos | 🧪 Test Drive | 💬 Discord
A packaged FLM Windows installer is available here: flm-setup.exe. For more details, see the release notes.
⚠️ Ensure NPU driver is 32.0.203.258 or later (check via Task Manager→Performance→NPU or Device Manager) — Driver Download.
After installation, open PowerShell (Win + X → I
). To run a model in terminal (CLI Mode):
flm run llama3.2:1b
Notes:
- Internet access to HuggingFace is required to download the optimized model kernels.
- By default, models are stored in:
C:\Users\<USER>\Documents\flm\models\
- During installation, you can select a different base folder (e.g., if you choose
C:\Users\<USER>\flm
, models will be saved underC:\Users\<USER>\flm\models\
).⚠️ If HuggingFace is not accessible in your region, manually download the model (check this issue) and place it in the chosen directory.
🎉🚀 FastFlowLM (FLM) is ready — your NPU is unlocked and you can start chatting with models right away!
Open Task Manager (Ctrl + Shift + Esc
). Go to the Performance tab → click NPU to monitor usage.
⚡ Quick Tips:
- Use
/verbose
during a session to turn on performance reporting (toggle off with/verbose
again).- Type
/bye
to exit a conversation.- Run
flm list
in PowerShell to show all available models.
To start the local server (Server Mode):
flm serve llama3.2:1b
The model tag (e.g.,
llama3.2:1b
) sets the initial model, which is optional. If another model is requested, FastFlowLM will automatically switch to it. Local server is on port 11434 (default).
FLM makes it easy to run cutting-edge LLMs (and now VLMs) locally with:
- ⚡ Fast and low power
- 🧰 Simple CLI and API (REST and OpenAI API)
- 🔐 Fully private and offline
No model rewrites, no tuning — it just works.
- Runs fully on AMD Ryzen™ AI NPU — no GPU or CPU load
- Developer-first flow — like Ollama, but optimized for NPU
- Support for long context windows — up to 256k tokens (e.g., Qwen3-4B-Thinking-2507)
- No low-level tuning required — You focus on your app, we handle the rest
- All orchestration code and CLI tools are open-source under the MIT License.
- NPU-accelerated kernels are proprietary binaries, free for non-commercial use only — see LICENSE_BINARY.txt and TERMS.md for details.
