+
+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
+
+- 🎧 **Multilingual ASR** — transcribes many languages and can translate speech to English
+- 🪶 **74M parameters** — a small footprint with noticeably better accuracy than tiny
+- 🌐 **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-base:q8
+
+# 3. Transcribe
+openasr transcribe audio.wav --model whisper-base
+```
+
+All builds for this model:
+
+```bash
+openasr pull whisper-base:fp16
+openasr pull whisper-base:q8
+openasr pull whisper-base:q4
+```
+
+## 📦 Available builds
+
+| Quant | File (`.oasr`) | Size | RAM peak | RTF · M1 CPU | RTF · M1 GPU | JFK ΔWER vs fp16 |
+|:------|:---------------|-----:|---------:|-------------:|-------------:|-----------------:|
+| fp16 | `whisper-base-fp16.oasr` | 149 MB | 542 MB | 0.08× | 0.06× | 0.0% |
+| q8_0 | `whisper-base-q8_0.oasr` | 108 MB | 405 MB | 0.07× | 0.06× | 0.0% |
+| q4_k | `whisper-base-q4_k.oasr` | 86 MB | 364 MB | 0.06× | 0.07× | 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 Base
+
+Whisper Base is OpenAI's 74M-parameter multilingual Whisper checkpoint. It uses the standard
+Whisper encoder-decoder architecture for automatic speech recognition and speech translation,
+trained with large-scale weak supervision on 680k hours of labelled speech. Base offers a
+meaningful accuracy gain over tiny while staying small and fast enough for low-resource
+devices. This OpenASR repo repackages the original `openai/whisper-base` 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 tighter memory budgets and fp16 is for
+verification or maximum fidelity.
+
+## ⚙️ How these packs were made
+
+Converted from [openai/whisper-base](https://huggingface.co/openai/whisper-base) with the OpenASR importer:
+
+```bash
+openasr model-pack import-whisper-local <src> <out>.oasr \
+  --package-id whisper-base --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.
+
+## ⚖️ License

+These packs **inherit the upstream model's license: Apache-2.0**
+([source](https://huggingface.co/openai/whisper-base/blob/main/README.md)). OpenASR packaging retains the upstream copyright and
+NOTICE; the only modifications are format conversion and quantization.

+All credit for the original model, training recipe, and weights belongs to OpenAI. The
+upstream Hugging Face model card declares Apache-2.0 licensing; OpenASR only converts the
+weights into `.oasr` packages and adds quantized builds for local runtime use.
