# Open4bits / Whisper Tiny FP16

This repository provides the **Whisper Tiny model converted to FP16 (float16) precision**, published by Open4bits to enable highly efficient inference with minimal memory usage.

The underlying Whisper model and architecture are **owned by OpenAI**. This repository contains only a precision-converted version of the original model weights.

The model is designed for fast, lightweight multilingual speech-to-text tasks and is well suited for resource-constrained environments.

---

## Model Overview

Whisper is a sequence-to-sequence transformer model developed by OpenAI for automatic speech recognition and speech translation.  
This release uses the **Tiny** variant, prioritizing speed and low memory usage while preserving the original architecture.

---

## Model Details

- **Architecture:** Whisper Tiny  
- **Parameters:** ~37.85 million  
- **Precision:** float16 (FP16)  
- **Task:** Automatic Speech Recognition (ASR)  
- **Languages:** Multilingual  
- **Weight tying:** Preserved  
- **Compatibility:** Hugging Face Transformers, PyTorch  

Compared to larger Whisper variants, this model offers significantly faster inference and lower VRAM requirements, with reduced accuracy in some scenarios.

---

## Intended Use

This model is intended for:
- Fast speech-to-text transcription
- Lightweight and real-time ASR applications
- Edge or low-resource deployments
- Research and prototyping

---

## Limitations

* Lower transcription accuracy compared to larger Whisper variants
* Performance depends on audio quality, language, and accent
* Not fine-tuned for domain-specific or noisy audio

---

## License

This model is released under the **Apache License 2.0**.
The original Whisper model and associated intellectual property are owned by OpenAI.
