+# Elastic model: Meta-Llama-3.1-8B-Instruct. Fastest and most flexible models for self-serving.
+
+Elastic models 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. For each model, ANNA produces 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%.
+
+
+__Goals of elastic models:__
+
+* 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.
+* Provide the best models and service for self-hosting.
+
+> 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.

+
+## Inference
+
+To infer our models, you just need to replace `transformers` import with `elastic_models.transformers`:
+
+```python
+import torch
+from transformers import AutoTokenizer
+from elastic_models.transformers import AutoModelForCausalLM
+
+# Currently we require to have your HF token
+# as we use original weights for part of layers and
+# model confugaration as well
+model_name = "meta-llama/Llama-3.2-1B-Instruct"
+hf_token = ''
+device = torch.device("cuda")
+
+# Create mode
+tokenizer = AutoTokenizer.from_pretrained(
+    model_name, token=hf_token
+)
+model = AutoModelForCausalLM.from_pretrained(
+    model_name, 
+    token=hf_token,
+    torch_dtype=torch.bfloat16,
+    attn_implementation="sdpa",
+    mode='s'
+).to(device)
+model.generation_config.pad_token_id = tokenizer.eos_token_id
+
+# Inference simple as transformers library
+prompt = "Describe basics of DNNs quantization."
+inputs = tokenizer(prompt, return_tensors="pt")
+inputs.to(device)
+
+with torch.inference_mode:
+    generate_ids = model.generate(**inputs, max_length=500)
+
+input_len = inputs['input_ids'].shape[1]
+generate_ids = generate_ids[:, input_len:]
+output = tokenizer.batch_decode(
+    generate_ids,
+    skip_special_tokens=True, 
+    clean_up_tokenization_spaces=False
+)[0]
+
+# Validate answer
+print(f"# Q:\n{prompt}\n")
+print(f"# A:\n{output}\n")
+```

+__System requirements:__
+* GPUs: H100, L40s
+* CPU: AMD, Intel
+* Python: 3.10-3.12
+
+
+TODO: UPDATE VERSION (0.0.4?)
+To work with our models just run these lines in your terminal:
+
+```shell
+pip install thestage
+pip install elastic_models==0.0.4\
+ --index-url https://thestage.jfrog.io/artifactory/api/pypi/pypi-thestage-ai-production/simple\
+ --extra-index-url https://pypi.nvidia.com\
+ --extra-index-url https://pypi.org/simple
+
+pip install flash_attn==2.7.3 --no-build-isolation
+pip uninstall apex
+```
+
+Then go to [app.thestage.ai](https://app.thestage.ai), login and generate API token from your profile page. Set up API token as follows:
+
+```shell
+thestage config set --api-token <YOUR_API_TOKEN>
+```
+
+Congrats, now you can use accelerated models!

+
+## Benchmarks
+
+Benchmarking is one of the most important procedures during model acceleration. We aim to provide clear performance metrics for models using our algorithms. The `W8A8, int8 column` indicates that we applied W8A8 quantization with int8 data type to all linear layers and used the same calibration data as for ANNA. The S model achieves practically identical speed but much higher quality, as ANNA knows how to improve quantization quality on sensitive layers!
