## Overview
---
ElasticModels are the models produced by TheStage AI ANNA: Automated Neural Networks Accelerator. ANNA allows you to control model size, latency and quality with a simple slider movement, routing different compression algorithms to different layers. For each model, we have produced a series of optimized models:
- **XL**: Mathematically equivalent neural network, optimized with our DNN compiler.
- **L**: Near lossless model, with less than 1% degradation obtained on corresponding benchmarks.
- **M**: Faster model, with accuracy degradation less than 1.5%.
- **S**: The fastest model, with accuracy degradation less than 2%.
**How to run this model:**
| Platform | Path |
| --- | --- |
| **Apple Silicon (iOS / macOS)** | [TheStage Apple SDK](#thestage-apple-sdk) — Swift / Flutter, on-device CoreML |
| **NVIDIA GPUs (Python)** | [ElasticModels](#elasticmodels) or [TheWhisper SpeechKit](#thewhisper-speechkit) |
| **NVIDIA serving** | [Docker / OpenAI-compatible API](#serving-with-docker-image) |
Models can be accessed via TheStage AI Python SDK (ElasticModels), the TheStage Apple SDK (Swift / Flutter), or deployed as Docker containers with REST API endpoints (see Deploy section).
## System Requirements

| **Property**| **Value** |
| --- | --- |
| **GPU** | L40s, RTX 4090, RTX 5090, H100 |
| **Python Version** | 3.10-3.12 |
| **CPU** | Intel/AMD x86_64 |
| **CUDA Version** | 12.8+ |

| **Hardware** | Apple Silicon Mac, or physical iPhone / iPad |
| **macOS** | 15.0+ |
| **iOS** | 18.0+ |
| **Xcode** | 16.0+ |
| **Swift** | 6.0+ |
| **Flutter** (optional) | 3.24+ |

## TheStage AI Access Token Setup
---
Install TheStage AI CLI and setup API token:
```bash
pip install thestage
thestage config set --access-token <YOUR_ACCESS_TOKEN>
```
For the Apple SDK, create a token at [app.thestage.ai](https://app.thestage.ai) and pass it to `TheStageAI.shared.initialize(apiToken:)` (Swift) or `TheStageFlutterSDK.initialize(api_token:)` (Flutter). Token is checked online in `initialize` (once per app process when reachable). Inference runs fully on-device. Offline initialize fails — reconnect and call `initialize` again.
## TheStage Apple SDK

---
On-device transcription for **iOS and macOS**. The SDK downloads CoreML engines from this Hugging Face repo, auto-selects Neural Engine / GPU / CPU, and exposes batch `infer` plus push-based live streaming. No server in the hot path.
Docs: [TheStage Apple SDK · Whisper](https://docs.thestage.ai) · Repo: [TheStage Apple SDK](https://github.com/TheStageAI/AppleSDK)
### Installation (SwiftPM)
In Xcode: **File → Add Package Dependencies…**, paste `https://github.com/TheStageAI/AppleSDK.git`, and add the `TheStageSDK` product. Or in `Package.swift`:
```swift
.package(
url: "https://github.com/TheStageAI/AppleSDK.git",
exact: Version(1, 1, 0)
)
```
### Swift — batch transcription
```swift
import TheStageSDK
let ai = TheStageAI.shared
try await ai.initialize(apiToken: "th_…")
let stt = try await WhisperPipeline(
engines_path: "TheStageAI/thewhisper-large-v3-turbo"
)
// audio: 16 kHz mono Float, samples in [-1.0, 1.0]
let result = stt.infer(audio: audio_samples, language: "en")
print(result.text)
```
Long audio is split into the bundle's window size (**10 s** for the shipping turbo engines). Optional constructor knobs: `device` (`"npu"` / `"gpu"` / `"cpu"`), `overlap_seconds`, `use_internal_vad`.
### Swift — live streaming
```swift
let streamer = stt.open_streamer(language: "en")
let captions = Task {
for await text in streamer.partials {
print("partial: \(text)") // committed-so-far, grows monotonically
}
}
for await frame in microphone_frames { // [Float] @ 16 kHz mono
streamer.send(frame)
if vad_detected_pause { streamer.flush() }
}
let final_text = await streamer.finish()
await captions.value
print("final: \(final_text)")
```
`partials` is for live UI; `finish()` is the authoritative end-of-turn transcript. Call `flush()` at VAD pauses to keep latency flat on long turns; `cancel()` for barge-in.
### Flutter (iOS)
```yaml
# pubspec.yaml
dependencies:
thestage_apple_sdk:
git:
url: https://github.com/TheStageAI/AppleSDK.git
path: plugin/thestage_apple_sdk
ref: 1.1.0
```
```dart
import 'package:thestage_apple_sdk/thestage_apple_sdk.dart';
import 'dart:typed_data';
await TheStageFlutterSDK.initialize(api_token: 'th_…');
await TheStageFlutterSDK.start_model(
model_name: 'stt',
engines_path: 'TheStageAI/thewhisper-large-v3-turbo',
);
// audio_samples: Float32List, 16 kHz mono, samples in [-1.0, 1.0]
final result = await TheStageFlutterSDK.infer(
model_name: 'stt',
input_json: {
'audio': audio_samples,
'language': 'en',
},
);
print(result[0]['transcription']);
```
JSON response keys: `transcription` (`String`), `token_count` (`Int`), `decode_seconds` (`Double`), optional `tokens` (`[Int]`).
### Audio contract (Apple)
| | |
| --- | --- |
| Sample rate | **16 kHz** mono |
| Sample type | `Float` / `Float32List` in `[-1.0, 1.0]` |
| Chunk window | **10 s** (read from the bundle; older 15 / 30 s exports also work) |
| Resampling | **Not** automatic — convert mic capture before `infer` / `send` |
### Prefetch / progress
```swift
let engines_dir = try await ai.prefetch_engines(
repo_id: "TheStageAI/thewhisper-large-v3-turbo"
)
let stt = try await WhisperPipeline(engines_path: engines_dir)
// Optional load progress:
let stt = try await WhisperPipeline(
engines_path: "TheStageAI/thewhisper-large-v3-turbo",
on_load_progress: { p in
print("[\(p.model)] \(p.phase) \(Int(p.fraction * 100))%")
}
)
```
### Apple on-device latency
Release build on **Apple M2 Max (NPU / ANE), macOS 26.2** (guidance, not an SLA):
| Metric | Value |
| --- | --- |
| RTFx (`audio_seconds / wall_seconds`) | **16.7** |
| Decode tok/s | **233** |
| Process mem | **~96 MB** |
Measured on a short ~2.6 s utterance; shipping windows are 10 s. Always bench release builds on device.
## ElasticModels
---
Elastic Models provides the same interface as HuggingFace Transformers. Here is an example of how to use the thewhisper-large-v3-turbo model.
### Installation
```bash
pip install 'thestage-elastic-models[nvidia]' \
--extra-index-url https://thestage.jfrog.io/artifactory/api/pypi/pypi-thestage-ai-production/simple
pip install datasets==3.6.0 librosa soundfile # only needed to load audio for the example below
```
### Usage
```python
import torch
from elastic_models.transformers import AutoModelForSpeechSeq2Seq
from transformers import AutoProcessor
model_name = "TheStageAI/thewhisper-large-v3-turbo"
hf_token = ''
device = torch.device("cuda")
processor = AutoProcessor.from_pretrained(
model_name, token=hf_token
)
model = AutoModelForSpeechSeq2Seq.from_pretrained(
model_name,
token=hf_token,
torch_dtype=torch.float16,
mode='S'
).to(device)
# Load audio file
from datasets import load_dataset
dataset = load_dataset(
"hf-internal-testing/librispeech_asr_dummy",
"clean", split="validation"
)
audio_sample = dataset[0]["audio"]
# Process audio
input_features = processor(
audio_sample["array"],
sampling_rate=audio_sample["sampling_rate"],
return_tensors="pt"
).input_features.to(device, dtype=torch.float16)
# Generate transcription
with torch.inference_mode():
predicted_ids = model.generate(input_features)
transcription = processor.batch_decode(
predicted_ids, skip_special_tokens=True
)[0]
print(f"Transcription: {transcription}")
```
## TheWhisper SpeechKit
---
TheWhisper can also be used via `thestage_speechkit` for NVIDIA and Apple Silicon inference from Python, including real-time streaming.
### Installation
```bash
# Install ffmpeg (required for audio processing)
# Ubuntu/Debian: apt install ffmpeg
# macOS: brew install ffmpeg
git clone https://github.com/TheStageAI/TheWhisper.git
cd TheWhisper
pip install .[nvidia] # or pip install .[apple] for Apple Silicon
```
For TheStage AI optimized engines (NVIDIA only):
```bash
pip install thestage-elastic-models[nvidia] --extra-index-url https://thestage.jfrog.io/artifactory/api/pypi/pypi-thestage-ai-production/simple
```
### NVIDIA Usage
```python
from thestage_speechkit.nvidia import ASRPipeline
model = ASRPipeline(
model='TheStageAI/thewhisper-large-v3-turbo',
model_size='S',
chunk_length_s=15,
batch_size=32,
device='cuda'
)
result = model(
"path_to_your_audio.wav",
chunk_length_s=15,
generate_kwargs={'do_sample': False, 'num_beams': 1, 'use_cache': True}
)
print(result["text"])
```
### Apple Silicon Usage (Python)
> For shipping iOS / macOS apps, prefer the [TheStage Apple SDK](#thestage-apple-sdk) above. SpeechKit remains available for Python notebooks and macOS scripting.
```python
from thestage_speechkit.apple import ASRPipeline
model = ASRPipeline(
model='TheStageAI/thewhisper-large-v3-turbo',
model_size='S',
chunk_length_s=10
)
result = model(
"path_to_your_audio.wav",
chunk_length_s=10,
generate_kwargs={'do_sample': False, 'num_beams': 1, 'use_cache': True}
)
print(result["text"])
```
### Streaming
```python
from thestage_speechkit.streaming import StreamingPipeline, MicStream, StdoutStream
streaming_pipe = StreamingPipeline(
model='TheStageAI/thewhisper-large-v3-turbo',
model_size='S',
chunk_length_s=15,
platform='apple',
language='en'
)
mic_stream = MicStream(step_size_s=0.5)
output_stream = StdoutStream()
while True:
chunk = mic_stream.next_chunk()
if chunk is not None:
approved_text, assumption = streaming_pipe(chunk)
output_stream.write(approved_text, assumption)
else:
break
```

## Benchmarking Methodology
---
The benchmarking was performed on a single GPU using a 10-minute audio file resampled to 16kHz mono. RTFx (Real-Time Factor) is calculated as `audio_duration / transcription_time` — higher values mean faster-than-real-time transcription.
> **Algorithm summary:**
> 1. Load the thewhisper-large-v3-turbo model with the specified size (S, M, L, XL, original).
> 2. Load a 10-minute audio file and resample to 16kHz mono.
> 3. Run a warm-up pass to initialize GPU caches.
> 4. Synchronize the GPU, record the start time.
> 5. Run the transcription pipeline with the specified batch size and chunk length.
> 6. Synchronize the GPU, record the end time.
> 7. Calculate RTFx as `audio_duration / time_taken`.
## Serving with Docker Image
---
For serving with Nvidia GPUs, we provide ready-to-go Docker containers with OpenAI-compatible API endpoints.
Using our containers you can set up an inference endpoint on any desired cloud/serverless providers as well as on-premise servers.
You can also use this container to run inference through TheStage AI platform.
