+Native speech-to-text in the **[OpenASR](https://github.com/QuintinShaw/openasr)** runtime —
+engineered for peak performance on CPU & GPU, **no Python at inference time**.
+
+</div>
+
+---
+
+## ✨ Highlights
+
+- 🇬🇧 **English-only** — specialized for English, typically more accurate on English than the same-size multilingual model
+- ⚡ **39M parameters** — the smallest, fastest, and lightest Whisper checkpoint
+- 🌐 **Weak-supervision scale** — trained with Whisper's 680k-hour labelled speech corpus
+- 🦀 **Native in OpenASR** — `.oasr` packs run with no Python at inference, engineered for peak performance on CPU & GPU
+
+## 🚀 Quickstart
+
+```bash
+# 1. Install the OpenASR CLI  ·  https://openasr.org
+# 2. Pull a build (pick a quant — see the table below)
+openasr pull whisper-tiny.en:q8
+
+# 3. Transcribe
+openasr transcribe audio.wav --model whisper-tiny.en
+```
+
+All builds for this model:
+
+```bash
+openasr pull whisper-tiny.en:fp16
+openasr pull whisper-tiny.en:q8
+openasr pull whisper-tiny.en:q4
+```
+
+## 📦 Available builds
+
+| Quant | File (`.oasr`) | Size | RAM peak | RTF · M1 CPU | RTF · M1 GPU | JFK ΔWER vs fp16 |
+|:------|:---------------|-----:|---------:|-------------:|-------------:|-----------------:|
+| fp16 | `whisper-tiny.en-fp16.oasr` | 79 MB | 325 MB | 0.05× | 0.05× | 0.0% |
+| q8_0 | `whisper-tiny.en-q8_0.oasr` | 63 MB | 277 MB | 0.05× | 0.04× | 0.0% |
+| q4_k | `whisper-tiny.en-q4_k.oasr` | 61 MB | 271 MB | 0.05× | 0.05× | 0.0% |
+
+<sub>RTF = real-time factor on the fixed 11s JFK clip (**lower is faster**); RAM peak measured per pack
+in an isolated subprocess. JFK ΔWER compares each quantized build's JFK transcript to this model's
+fp16 JFK transcript, so it measures quantization drift rather than absolute recognition accuracy.
+**q8_0** is the recommended default — near-reference quality at a fraction of the
+footprint.</sub>
+
+## 🧠 About Whisper Tiny (English)
+
+Whisper Tiny.en is OpenAI's 39M-parameter English-only Whisper checkpoint. It uses the standard
+Whisper encoder-decoder architecture for automatic speech recognition, trained with large-scale
+weak supervision on 680k hours of labelled speech. As an English-specialized model it tends to
+outperform the same-size multilingual Whisper on English audio, at the lowest footprint and
+fastest inference in the family. This OpenASR repo repackages the original `openai/whisper-tiny.en`
+weights as `.oasr` packs that run natively in the OpenASR runtime with no Python at inference
+time. For most users the q8_0 build is the recommended default; q4_k is for the tightest memory
+budgets and fp16 is for verification or maximum fidelity.
+
+## ⚙️ How these packs were made
+
+Converted from [openai/whisper-tiny.en](https://huggingface.co/openai/whisper-tiny.en) with the OpenASR importer:
+
+```bash
+openasr model-pack import-whisper-local <src> <out>.oasr \
+  --package-id whisper-tiny.en --quantization {fp16,q8-0,q4-k}
+```
+
+The `.oasr` container is GGUF-backed; packs use zero-copy mmap weight binding and graph
+buffer reuse to keep peak memory low.

+([source](https://huggingface.co/openai/whisper-tiny.en/blob/main/README.md)). OpenASR packaging retains the upstream copyright and
