# LFM2.5-230M-ONNX
|
| 45 |
+
|
| 46 |
+
ONNX export of [LFM2.5-230M](https://huggingface.co/LiquidAI/LFM2.5-230M) for cross-platform inference.
|
| 47 |
+
|
| 48 |
+
LFM2.5 is a hybrid architecture combining multiplicative gates and short convolutions, optimized for edge deployment with fast inference on CPU, GPU, and NPU hardware.
|
| 49 |
+
|
| 50 |
+
## Recommended Variants
|
| 51 |
+
|
| 52 |
+
| Variant | Size | Description |
|
| 53 |
+
|---------|---------|-------------|
|
| 54 |
+
| FP16 | ~455 MB | All weights in FP16 |
|
| 55 |
+
| Q4 | ~200 MB | INT4 embedding (GatherBlockQuantized), INT4 lm_head (MatMulNBits, shared), INT4 MatMul weights |
|
| 56 |
+
| Q4F32 | ~390 MB | INT4 MatMul weights, FP32 embedding and norms |
|
| 57 |
+
| Q8 | ~470 MB | INT8 MatMul weights, FP32 embedding and norms |
|
| 58 |
+
|
| 59 |
+
Q4 uses GatherBlockQuantized for the token embedding and MatMulNBits for the lm_head,
|
| 60 |
+
reusing the same quantized weights and scales. All other linear layers are quantized to
|
| 61 |
+
INT4 via post-export MatMulNBitsQuantizer. Block size is 32.
|
| 62 |
+
|
| 63 |
+
Q4F32 keeps the embedding as a FP32 Gather and the lm_head as FP32 Transpose + MatMul.
|
| 64 |
+
Only the internal linear layers (attention projections, conv projections, MLP) are
|
| 65 |
+
quantized to INT4 via post-export MatMulNBitsQuantizer.
|
| 66 |
+
|
| 67 |
+
Q8 is the same structure as Q4F32 but with INT8 weights (asymmetric quantization).

## WebGPU (Browser)
|
| 202 |
+
|
| 203 |
+
### Installation
|
| 204 |
+
|
| 205 |
+
```bash
|
| 206 |
+
npm install onnxruntime-web @huggingface/transformers
|
| 207 |
+
```
|
| 208 |
+
|
| 209 |
+
### Enable WebGPU
|
| 210 |
+
|
| 211 |
+
WebGPU is required for browser inference. To enable:
|
| 212 |
+
|
| 213 |
+
1. **Chrome/Edge**: Navigate to `chrome://flags/#enable-unsafe-webgpu`, enable, and restart
|
| 214 |
+
2. **Verify**: Check `chrome://gpu` for "WebGPU" status
|
| 215 |
+
3. **Test**: Run `navigator.gpu.requestAdapter()` in DevTools console
|
| 216 |
+
|
| 217 |
+

### WebGPU Notes
|
| 356 |
+
|
| 357 |
+
* Models use external data files (`.onnx_data`) that are loaded automatically
|
| 358 |
+
* int64 tensors require `BigInt64Array`
|
| 359 |
+
|
| 360 |
+
## Building from Source
|
| 361 |
+
|
| 362 |
+
This ONNX package was created using the official [Liquid4All/onnx-export](https://github.com/Liquid4All/onnx-export) tool (the reference exporter for all LFM2/LFM2.5 ONNX checkpoints).
|
| 363 |
+
|
| 364 |
+
```bash
|
| 365 |
+
git clone https://github.com/Liquid4All/onnx-export.git
|
| 366 |
+
cd onnx-export
|
| 367 |
+
uv sync
|
| 368 |
+
|
| 369 |
+
# Export all precisions (fp16, q4, q4f32, q8) + FP32 base
|
| 370 |
+
uv run lfm2-export LiquidAI/LFM2.5-230M --precision
|
| 371 |
+
```
|
| 372 |
+
|
| 373 |
+
The output lands in `exports/LFM2.5-230M-ONNX/`. Copy its contents (or the `onnx/` subdir + metadata) to your target repo root for publishing to the Hugging Face Hub.
|
| 374 |
+
|
| 375 |
+
The builder manually constructs the ONNX graph (using `onnx.helper`) for maximum compatibility with ONNX Runtime WebGPU, Transformers.js, and Microsoft custom ops (SimplifiedLayerNormalization, RotaryEmbedding, GroupQueryAttention, GatherBlockQuantized, MatMulNBits, etc.). Standard `torch.onnx.export` is not used.
