# LFM2-2.6B-Transcript-ONNX
|
| 36 |
+
|
| 37 |
+
ONNX export of [LFM2-2.6B-Transcript](https://huggingface.co/LiquidAI/LFM2-2.6B-Transcript) for cross-platform inference.
|
| 38 |
+
|
| 39 |
+
LFM2-2.6B-Transcript is optimized for processing and summarizing meeting transcripts, extracting key points, action items, and decisions from conversational text.

+
## Recommended Variants
|
| 42 |
+
|
| 43 |
+
| Precision | Size | Platform | Use Case |
|
| 44 |

|-----------|------|----------|----------|
|
| 45 |
+
| Q4 | ~2.0GB | WebGPU, Server | Recommended for most uses |
|
| 46 |
+
| FP16 | ~4.8GB | WebGPU, Server | Higher quality |
|
| 47 |
+
| Q8 | ~3.0GB | Server only | Balance of quality and size |
|
