+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:
 
-* __M__: Faster model, with accuracy degradation less than 1.5%.
+- **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%.
 
-* __S__: The fastest model, with accuracy degradation less than 2%.
+Models can be accessed via TheStage AI Python SDK: ElasticModels, or deployed as Docker containers with REST API endpoints (see Deploy section).

+## Installation
+
+### System Requirements
+
+| **Property**| **Value** |
+ | ---  | ---  |
+| **GPU** | L40s, RTX 5090, H100, B200 |
+| **Python Version** | 3.10-3.12 |
+| **CPU** | Intel/AMD x86_64 |
+| **CUDA Version** | 12.8+ |
 
-__Goals of Elastic Models:__
 
-* Provide the fastest models and service for self-hosting.
-* Provide flexibility in cost vs quality selection for inference.
-* Provide clear quality and latency benchmarks.
-* Provide interface of HF libraries: transformers and diffusers with a single line of code.
-* Provide models supported on a wide range of hardware, which are pre-compiled and require no JIT.
+### TheStage AI Access token setup
 
-> It's important to note that specific quality degradation can vary from model to model. For instance, with an S model, you can have 0.5% degradation as well.
+Install TheStage AI CLI and setup API token:
 
------
+```bash
+pip install thestage
+thestage config set --access-token <YOUR_ACCESS_TOKEN>

+
+## Benchmarking Methodology
+
+The benchmarking was performed on a single GPU with a batch size of 1. Each model was run for 10 iterations, and the average latency was calculated.
+
+> **Algorithm summary:**
+> 1. Load the FLUX.1-schnell model with the specified size (S, M, L, XL, original).
+> 2. Move the model to the GPU.
+> 3. Prepare a sample prompt for image generation.
+> 4. Run the model for a number of iterations (e.g., 10) and measure the time taken for each iteration. On each iteration:
+>    - Synchronize the GPU to flush any previous operations.
+>    - Record the start time.
+>    - Generate the image using the model.
+>    - Synchronize the GPU again.
+>    - Record the end time and calculate the latency for that iteration.
+> 5. Calculate the average latency over all iterations.

+## 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.
