+
+## 🚀 Release Process
+
+### Development Workflow
+
+1. **Feature Development**
+
+   ```bash
+   git checkout -b feature/your-feature-name
+   # Make your changes
+   git push origin feature/your-feature-name
+   ```
+
+   - Creates pull request → triggers dev build: `runpod/worker-v1-vllm:dev-refs-pull-214-merge`
+
+2. **Main Branch**
+   ```bash
+   git checkout main
+   git merge feature/your-feature-name
+   git push origin main
+   ```
+   - No automatic builds on main (staging area)
+
+### Creating Releases
+
+**Method 1: GitHub UI (Recommended)**
+
+1. Go to [Releases](https://github.com/runpod-workers/worker-vllm/releases)
+2. Click **"Create a new release"**
+3. **Tag version**: `v2.8.0` (with "v" prefix, semantic versioning)
+4. **Target**: `main` branch
+5. **Title**: `Release 2.8.0`
+6. **Description**: Brief changelog
+7. Click **"Publish release"**
+
+**Method 2: Git CLI**
+
+```bash
+git checkout main
+git tag v2.8.0
+git push origin v2.8.0
+```
+
+### What Happens Automatically
+
+✅ **GitHub Release** created (if using Method 1)  
+✅ **Docker Image** built and pushed: `runpod/worker-v1-vllm:v2.8.0`  
+✅ **Documentation** updated with new version references
+
+## 📋 Version Format
+
+- **Format**: `vMAJOR.MINOR.PATCH` (e.g., `v2.8.0`)
+- **With "v" prefix**: Use `v2.8.0` for git tags
+- **Semantic Versioning**: Follow [SemVer](https://semver.org/)
+
+## 🐛 Development
+
+### Running Tests
+
+```bash
+# Update test configuration in .runpod/tests.json
+# Tests run automatically via RunPod platform
+```
+
+### Model Updates
+
+- Update `MODEL_NAME` in `.runpod/tests.json` and `worker-config.json`
+- Ensure model has vLLM support and chat template (for OpenAI compatibility)
+
+### Environment Variables
+
+See [README.md](../README.md) for full list of supported environment variables.
+
+## 🔧 CI/CD Workflows
+
+- **Dev builds**: All pull requests → `dev-refs-pull-<PR#>-merge` images
+- **Release builds**: Git tags → versioned images + GitHub releases
+- **Manual triggers**: Available in GitHub Actions for emergency releases

+
+## API Usage
+
+This worker supports two API formats: **RunPod native** and **OpenAI-compatible**.
+
+### RunPod Native API
+
+For testing directly in the RunPod UI, use these examples in your endpoint's request tab.
+
+#### Chat Completions
+
+```json
+{
+  "input": {
+    "messages": [
+      { "role": "system", "content": "You are a helpful assistant." },
+      { "role": "user", "content": "What is the capital of France?" }
+    ],
+    "sampling_params": {
+      "max_tokens": 100,
+      "temperature": 0.7
+    }
+  }
+}
+```
+
+#### Chat Completions (Streaming)
+
+```json
+{
+  "input": {
+    "messages": [
+      { "role": "user", "content": "Write a short story about a robot." }
+    ],
+    "sampling_params": {
+      "max_tokens": 500,
+      "temperature": 0.8
+    },
+    "stream": true
+  }
+}
+```
+
+#### Text Generation
+
+For direct text generation without chat format:
+
+```json
+{
+  "input": {
+    "prompt": "The capital of France is",
+    "sampling_params": {
+      "max_tokens": 64,
+      "temperature": 0.0
+    }
+  }
+}
+```
+
+#### List Models
+
+```json
+{
+  "input": {
+    "openai_route": "/v1/models"
+  }
+}
+```
+
+---
+
+### OpenAI-Compatible API
+
+For external clients and SDKs, use the `/openai/v1` path prefix with your RunPod API key.
+
+#### Chat Completions
+
+**Path:** `/openai/v1/chat/completions`
+
+```json
+{
+  "model": "meta-llama/Llama-2-7b-chat-hf",
+  "messages": [
+    { "role": "system", "content": "You are a helpful assistant." },
+    { "role": "user", "content": "What is the capital of France?" }
+  ],
+  "max_tokens": 100,
+  "temperature": 0.7
+}
+```
+
+#### Chat Completions (Streaming)
+
+```json
+{
+  "model": "meta-llama/Llama-2-7b-chat-hf",
+  "messages": [
+    { "role": "user", "content": "Write a short story about a robot." }
+  ],
+  "max_tokens": 500,
+  "temperature": 0.8,
+  "stream": true
+}
+```
+
+#### Text Completions
+
+**Path:** `/openai/v1/completions`
+
+```json
+{
+  "model": "meta-llama/Llama-2-7b-chat-hf",
+  "prompt": "The capital of France is",
+  "max_tokens": 100,
+  "temperature": 0.7
+}
+```
+
+#### List Models
+
+**Path:** `/openai/v1/models`
+
+```json
+{}
+```
+
+#### Response Format
+
+Both APIs return the same response format:
+
+```json
+{
+  "choices": [
+    {
+      "index": 0,
+      "message": { "role": "assistant", "content": "Paris." },
+      "finish_reason": "stop"
+    }
+  ],
+  "usage": { "prompt_tokens": 9, "completion_tokens": 1, "total_tokens": 10 }
+}
+```
+
+---
+
+## Usage
+
+Below are minimal `python` snippets so you can copy-paste to get started quickly.
+
+> Replace `<ENDPOINT_ID>` with your endpoint ID and `<API_KEY>` with a [RunPod API key](https://docs.runpod.io/get-started/api-keys).
+
+### OpenAI compatible API
+
+Minimal Python example using the official `openai` SDK:
+
+```python
+from openai import OpenAI
+import os
+
+# Initialize the OpenAI Client with your RunPod API Key and Endpoint URL
+client = OpenAI(
+    api_key=os.getenv("RUNPOD_API_KEY"),
+    base_url=f"https://api.runpod.ai/v2/<ENDPOINT_ID>/openai/v1",
+)
+```
+
+`Chat Completions (Non-Streaming)`
+
+```python
+response = client.chat.completions.create(
+    model="meta-llama/Llama-2-7b-chat-hf",
+    messages=[{"role": "user", "content": "Explain quantum computing in simple terms"}],
+    temperature=0,
+    max_tokens=100,
+)
+print(f"Response: {response.choices[0].message.content}")
+```
+
+`Chat Completions (Streaming)`
+
+```python
+response_stream = client.chat.completions.create(
+    model="meta-llama/Llama-2-7b-chat-hf",
+    messages=[{"role": "user", "content": "Explain quantum computing in simple terms"}],
+    temperature=0,
+    max_tokens=100,
+    stream=True
+)
+for response in response_stream:
+    print(response.choices[0].delta.content or "", end="", flush=True)
+```
+
+### RunPod Native API
+
+```python
+import requests
+
+response = requests.post(
+    "https://api.runpod.ai/v2/<ENDPOINT_ID>/run",
+    headers={"Authorization": "Bearer <API_KEY>"},
+    json={
+        "input": {
+            "messages": [
+                {"role": "system", "content": "You are a helpful assistant."},
+                {"role": "user", "content": "Explain quantum computing in simple terms"}
+            ],
+            "sampling_params": {
+                "temperature": 0.7,
+                "max_tokens": 150
+            }
+        }
+    }
+)
+
+result = response.json()
+print(result["output"])
+```
+
+## Compatibility
+
+For supported models, see the [vLLM supported models documentation](https://docs.vllm.ai/en/latest/models/supported_models.html).
+
+Anything not recognized by worker-vllm is forwarded to vLLM's engine, so advanced options in the vLLM docs (guided generation, LoRA, speculative decoding, etc.) also work.

-| `BLOCK_SIZE`                        | `16`                 | `8`, `16`, `32`                           |Token block size for contiguous chunks of tokens. |

-| `ENFORCE_EAGER`                     | False                  | `bool`                                         |Always use eager-mode PyTorch. If False(`0`), will use eager mode and CUDA graph in hybrid for maximal performance and flexibility. |

-**Streaming Batch Size Settings**:  
-| `DEFAULT_BATCH_SIZE`                | `50`                 | `int`                                         |Default and Maximum batch size for token streaming to reduce HTTP calls. |

-The way this works is that the first request will have a batch size of `DEFAULT_MIN_BATCH_SIZE`, and each subsequent request will have a batch size of `previous_batch_size * DEFAULT_BATCH_SIZE_GROWTH_FACTOR`. This will continue until the batch size reaches `DEFAULT_BATCH_SIZE`. E.g. for the default values, the batch sizes will be `1, 3, 9, 27, 50, 50, 50, ...`. You can also specify this per request, with inputs `max_batch_size`, `min_batch_size`, and `batch_size_growth_factor`. This has nothing to do with vLLM's internal batching, but rather the number of tokens sent in each HTTP request from the worker |

-| `DISABLE_LOG_STATS`                 | False                  | `bool`                                         |Enables or disables vLLM stats logging. |

+### (Optional) Including Huggingface Token
+
 If the model you would like to deploy is private or gated, you will need to include it during build time as a Docker secret, which will protect it from being exposed in the image and on DockerHub.
+
 1. Enable Docker BuildKit (required for secrets).
+
 ```bash
 export DOCKER_BUILDKIT=1
 ```
+
 2. Export your Hugging Face token as an environment variable
+
 ```bash
 export HF_TOKEN="your_token_here"
 ```
+
 2. Add the token as a secret when building
+
 ```bash
 docker build -t username/image:tag --secret id=HF_TOKEN --build-arg MODEL_NAME="openchat/openchat_3.5" .

+You can deploy **any model on Hugging Face** that is supported by vLLM. For the complete and up-to-date list of supported model architectures, see the [vLLM Supported Models documentation](https://docs.vllm.ai/en/latest/models/supported_models.html#list-of-text-only-language-models).
 
 # Usage: OpenAI Compatibility
+
 The vLLM Worker is fully compatible with OpenAI's API, and you can use it with any OpenAI Codebase by changing only 3 lines in total. The supported routes are <ins>Chat Completions</ins> and <ins>Models</ins> - with both streaming and non-streaming.

 **Python** (similar to Node.js, etc.):
-1. When initializing the OpenAI Client in your code, change the `api_key` to your RunPod API Key and the `base_url` to your RunPod Serverless Endpoint URL in the following format: `https://api.runpod.ai/v2/<YOUR ENDPOINT ID>/openai/v1`, filling in your deployed endpoint ID. For example, if your Endpoint ID is `abc1234`, the URL would be `https://api.runpod.ai/v2/abc1234/openai/v1`. 
-    
-    - Before:
-    ```python
-    from openai import OpenAI
 
-    client = OpenAI(api_key=os.environ.get("OPENAI_API_KEY"))

+### Text Input Formats
 
-### Text Input Formats 
 You may either use a `prompt` or a list of `messages` as input.
- 1. `prompt` 
-The prompt string can be any string, and the model's chat template will not be applied to it unless `apply_chat_template` is set to `true`, in which case it will be treated as a user message.
 
-    Example:
-    ```json
-    "prompt": "..."
-    ```
-2. `messages`
-Your list can contain any number of messages, and each message usually can have any role from the following list:
-    - `user`
-    - `assistant`
-    - `system`
+1.  `prompt`
+    The prompt string can be any string, and the model's chat template will not be applied to it unless `apply_chat_template` is set to `true`, in which case it will be treated as a user message.
+
+        Example:
+        ```json
+        {
+          "input": {
+            "prompt": "why sky is blue?",
+            "sampling_params": {
+              "temperature": 0.7,
+              "max_tokens": 100
+            }
+          }
+        }
+        ```
+
+2.  `messages`
+    Your list can contain any number of messages, and each message usually can have any role from the following list: - `user` - `assistant` - `system`
 
     However, some models may have different roles, so you should check the model's chat template to see which roles are required.
 
     The model's chat template will be applied to the messages automatically, so the model must have one.
 
     Example:
+
     ```json
-    "messages": [
-        {

-# Worker Config
-The worker config is a JSON file that is used to build the form that helps users configure their serverless endpoint on the RunPod Web Interface.
-
-Note: This is a new feature and only works for workers that use one model 
-
-## Writing your worker-config.json
-The JSON consists of two main parts, schema and versions.
-- `schema`: Here you specify the form fields that will be displayed to the user.
-  - `env_var_name`: The name of the environment variable that is being set using the form field.
-  - `value`: This is the default value of the form field. It will be shown in the UI as such unless the user changes it.
-  - `title`: This is the title of the form field in the UI.
-  - `description`: This is the description of the form field in the UI.
-  - `required`: This is a boolean that specifies if the form field is required.
-  - `type`: This is the type of the form field. Options are:
-    - `text`: Environment variable is a string so user inputs text in form field.
-    - `select`: User selects one option from the dropdown. You must provide the `options` key value pair after type if using this.
-    - `toggle`: User toggles between true and false.
-    - `number`: User inputs a number in the form field.
-  - `options`: Specify the options the user can select from if the type is `select`. DO NOT include this unless the `type` is `select`.
-- `versions`: This is where you call the form fields specified in `schema` and organize them into categories.
-  - `imageName`: This is the name of the Docker image that will be used to run the serverless endpoint.
-  - `minimumCudaVersion`: This is the minimum CUDA version that is required to run the serverless endpoint.
-  - `categories`: This is where you call the keys of the form fields specified in `schema` and organize them into categories. Each category is a toggle list of forms on the Web UI.
-    - `title`: This is the title of the category in the UI.
-    - `settings`: This is the array of settings schemas specified in `schema` associated with the category.
-

+## Streaming & Batch Settings
+
+The way this works is that the first request will have a batch size of `DEFAULT_MIN_BATCH_SIZE`, and each subsequent request will have a batch size of `previous_batch_size * DEFAULT_BATCH_SIZE_GROWTH_FACTOR`. This will continue until the batch size reaches `DEFAULT_BATCH_SIZE`. E.g. for the default values, the batch sizes will be `1, 3, 9, 27, 50, 50, 50, ...`. You can also specify this per request, with inputs `max_batch_size`, `min_batch_size`, and `batch_size_growth_factor`. This has nothing to do with vLLM's internal batching, but rather the number of tokens sent in each HTTP request from the worker.

+# Worker vLLM - Development Conventions & Architecture Guide
+
+## Project Overview
+
+**worker-vllm** is a RunPod serverless worker that provides OpenAI-compatible endpoints for Large Language Model (LLM) inference, powered by the vLLM engine. It enables blazing-fast LLM deployment on RunPod's serverless infrastructure with minimal configuration.
+
+### Core Purpose
+
+- **Primary Function**: Deploy any Hugging Face LLM as an OpenAI-compatible API endpoint
+- **Platform**: RunPod Serverless infrastructure
+- **Engine**: vLLM (high-performance LLM inference engine)
+- **Compatibility**: Drop-in replacement for OpenAI API (Chat Completions, Models)
+
+## High-Level Architecture
+
+### 1. **Entry Point & Request Flow**
+
+```
+RunPod Request → handler.py → JobInput → Engine Selection → vLLM Generation → Streaming Response
+```
+
+**Key Components:**
+
+- `src/handler.py`: Main entry point using RunPod serverless framework
+- `src/utils.py`: Request parsing and utility classes (`JobInput`, `BatchSize`)
+- Two engine modes: OpenAI-compatible vs. standard vLLM
+
+### 2. **Engine Architecture**
+
+#### Core Classes:
+
+- **`vLLMEngine`**: Base engine handling vLLM initialization and generation
+- **`OpenAIvLLMEngine`**: Wrapper providing OpenAI API compatibility
+- **Engine Selection**: Automatic routing based on `job_input.openai_route`
+
+#### Key Design Patterns:
+
+- **Dual API Support**: Same codebase serves both OpenAI-compatible and native vLLM APIs
+- **Streaming by Default**: Token-level streaming with configurable batching
+- **Dynamic Batching**: Adaptive batch sizes that grow from min → max for efficiency
+
+### 3. **Configuration System**
+
+#### Environment-Based Configuration:
+
+- **Single Source of Truth**: All configuration via environment variables
+- **Hierarchical Loading**: `DEFAULT_ARGS` → `os.environ` → `local_model_args.json` (for baked models)
+- **vLLM Argument Mapping**: Automatic translation of env vars to vLLM `AsyncEngineArgs`
+
+#### Key Configuration Files:
+
+- `src/engine_args.py`: Centralized configuration management
+- `src/constants.py`: Default values for core settings
+- `.runpod/hub.json`: Hub UI configuration (CRITICAL: always update when changing defaults)
+- `worker-config.json`: UI form generation for RunPod console (if exists)
+
+## Core Development Concepts
+
+### 1. **Deployment Models**
+
+#### Option 1: Pre-built Images (Recommended)
+
+- **Image**: `runpod/worker-v1-vllm:<version>` (see [GitHub Releases](https://github.com/runpod-workers/worker-vllm/releases))
+- **Configuration**: Entirely via environment variables
+- **Model Loading**: Downloads model at runtime from Hugging Face
+- **Use Case**: Quick deployment, model experimentation
+
+#### Option 2: Baked Model Images
+
+- **Build Process**: Model downloaded during Docker build
+- **Storage**: Model embedded in container image
+- **Configuration**: Stored in `/local_model_args.json`
+- **Use Case**: Production deployments, faster cold starts
+
+### 2. **Request Processing Patterns**
+
+#### Input Handling:
+
+```python
+class JobInput:
+    - llm_input: str | List[Dict] (prompt or messages)
+    - sampling_params: SamplingParams (generation settings)
+    - stream: bool (streaming vs batch response)
+    - openai_route: bool (API compatibility mode)
+    - batch_size configs: Dynamic batching parameters
+```
+
+#### Response Streaming:
+
+- **Batched Streaming**: Tokens grouped into configurable batch sizes
+- **Dynamic Growth**: `min_batch_size * growth_factor^n` up to `max_batch_size`
+- **Usage Tracking**: Input/output token counting for billing
+
+### 3. **Model & Tokenizer Management**
+
+#### Tokenizer Handling:
+
+- **Wrapper Pattern**: `TokenizerWrapper` for consistent chat template application
+- **Special Cases**: Mistral models use vLLM's native tokenizer
+- **Chat Templates**: Automatic application for message-based inputs
+
+#### Model Loading:
+
+- **Multi-GPU Support**: Automatic tensor parallelism detection
+- **Quantization**: Support for AWQ, GPTQ, BitsAndBytes
+- **Caching**: Hugging Face cache management
+
+## Development Patterns & Best Practices
+
+### 1. **Code Organization**
+
+#### File Structure:
+
+```
+src/
+├── handler.py          # RunPod entry point
+├── engine.py          # Core vLLM engines
+├── engine_args.py     # Configuration management
+├── utils.py           # Request parsing & utilities
+├── tokenizer.py       # Tokenizer wrapper
+├── constants.py       # Default constants
+└── download_model.py  # Model downloading logic
+```
+
+#### Separation of Concerns:
+
+- **Engine Logic**: Isolated in `engine.py` classes
+- **Configuration**: Centralized in `engine_args.py`
+- **Request Handling**: Abstracted via `JobInput` class
+- **Platform Integration**: Contained in `handler.py`
+
+### 2. **Error Handling & Logging**
+
+#### Logging Strategy:
+
+- **Structured Logging**: Consistent format across components
+- **Performance Tracking**: Timer decorators for critical operations
+- **Error Context**: Detailed error messages with configuration context
+
+#### Error Responses:
+
+- **OpenAI Compatibility**: Standard OpenAI error format
+- **Graceful Degradation**: Fallback behaviors for edge cases
+
+### 3. **Environment Variable Conventions**
+
+#### Naming Patterns:
+
+- **vLLM Settings**: Match vLLM parameter names (uppercase)
+- **RunPod Settings**: `MAX_CONCURRENCY`, `DEFAULT_BATCH_SIZE`
+- **OpenAI Settings**: `OPENAI_` prefix for compatibility settings
+- **Feature Flags**: `ENABLE_*`, `DISABLE_*` pattern
+
+#### Type Conventions:
+
+- **Booleans**: String 'true'/'false' or int 0/1
+- **Lists**: Comma-separated strings
+- **Objects**: JSON strings for complex configurations
+
+### 4. **Docker & Deployment**
+
+#### Multi-Stage Builds:
+
+- **Base**: CUDA runtime environment
+- **Dependencies**: Python packages and vLLM
+- **Model Download**: Optional model baking stage
+- **Runtime**: Final application layer
+
+#### Build Arguments:
+
+- **MODEL_NAME**: Primary model identifier
+- **BASE_PATH**: Storage location strategy
+- **QUANTIZATION**: Optimization settings
+- **WORKER_CUDA_VERSION**: CUDA compatibility
+
+#### CI/CD Strategy:
+
+- **Development Builds**: All non-main branches → `runpod/worker-v1-vllm:dev-<branch-name>`
+- **Release Builds**: Git tags (numeric) only → `runpod/worker-v1-vllm:<version>`
+- **Dependency Updates**: Automated runpod package version monitoring
+
+#### Docker Bake Configuration:
+
+- **File**: `docker-bake.hcl` (flexible variable-based configuration)
+- **Variables**: `DOCKERHUB_REPO`, `DOCKERHUB_IMG`, `RELEASE_VERSION`, `HUGGINGFACE_ACCESS_TOKEN`
+- **Platform**: `linux/amd64` (GPU-optimized)
+
+## Release & Versioning Strategy
+
+### 1. **Version Tagging**
+
+- **Development**: `dev-<branch-name>` (e.g., `dev-feature-new-api`)
+- **Specific Versions**: `2.7.0`, `2.8.0` (semantic versioning without "v" prefix)
+- **Version Discovery**: Check [GitHub Releases](https://github.com/runpod-workers/worker-vllm/releases) for available versions
+
+### 2. **Release Workflow**
+
+1. **Feature Development**: Work on feature branches → triggers dev builds
+2. **Main Branch Staging**: Merge features to main → stable codebase (no builds)
+3. **Version Release**: Create git tag from main branch (e.g., `2.8.0`) → triggers versioned release + GitHub release
+4. **Docker Hub**: Versioned image pushed with tag
+
+### 3. **Branch Strategy**
+
+- **Feature Branches**: `feature/*`, `fix/*`, `feat/*` etc. → Dev builds
+- **Main Branch**: Stable codebase ready for release (no automatic builds)
+- **Git Tags**: Must be created from main branch for formal version releases
+
+### 4. **Deployment Recommendations**
+
+- **Production**: Use specific version tags (e.g., `2.7.0`) for stability
+- **Development**: Use `dev-<branch>` for testing specific features
+- **Version Selection**: Check [GitHub Releases](https://github.com/runpod-workers/worker-vllm/releases) for available versions
+- **Release Process**: Always tag from main branch: `git checkout main && git tag 2.8.0 && git push origin 2.8.0`
+
+## Performance & Scaling Considerations
+
+### 1. **Memory Management**
+
+- **GPU Utilization**: Default 95% GPU memory utilization
+- **KV Cache**: Configurable cache types (auto, fp8)
+- **Swap Space**: CPU offloading for large contexts
+
+### 2. **Concurrency Patterns**
+
+- **Max Concurrency**: 30 concurrent requests by default
+- **vLLM Queuing**: Internal request batching and scheduling
+- **RunPod Integration**: Concurrency modifier for auto-scaling
+
+### 3. **Optimization Features**
+
+- **Prefix Caching**: Automatic caching of common prefixes
+- **Speculative Decoding**: Draft model acceleration
+- **Chunked Prefill**: Memory-efficient long context handling
+
+## Testing & Development
+
+### 1. **Local Development**
+
+- **Environment**: Virtual environment with GPU support
+- **Configuration**: `.env` files for local testing
+- **Model Testing**: Small models for development (facebook/opt-125m)
+
+### 2. **Docker Development**
+
+- **Build Strategy**: `docker-bake.hcl` for consistent builds
+- **Testing Images**: Separate dev/stable image tags
+- **Layer Caching**: Optimized for rapid iteration
+
+### 3. **Configuration Validation**
+
+- **Argument Matching**: Automatic validation against vLLM parameters
+- **Environment Validation**: Type checking and default value handling
+- **Runtime Validation**: Model compatibility checks
+
+## API Conventions
+
+### 1. **OpenAI Compatibility**
+
+- **Endpoint Mapping**: `/openai/v1/chat/completions`, `/openai/v1/models`
+- **Request Format**: Exact OpenAI request/response schemas
+- **Authentication**: RunPod API key in Authorization header
+- **Model Names**: Hugging Face repo names or custom overrides
+
+### 2. **Native vLLM API**
+
+- **Input Format**: `prompt` or `messages` with `sampling_params`
+- **Streaming**: Token-level streaming with configurable batching
+- **Extensibility**: Support for vLLM-specific features
+
+## Common Patterns & Utilities
+
+### 1. **Configuration Loading**
+
+```python
+# Standard pattern for new configuration options
+def get_engine_args():
+    args = DEFAULT_ARGS
+    args.update(os.environ)  # Environment override
+    args.update(get_local_args())  # Baked model override
+    return match_vllm_args(args)  # Validate against vLLM
+```
+
+### 2. **Error Handling**
+
+```python
+# Standard error response pattern
+def create_error_response(message: str, err_type: str = "BadRequestError"):
+    return ErrorResponse(message=message, type=err_type)
+```
+
+### 3. **Async Generation**
+
+```python
+# Standard streaming pattern
+async def generate(self, job_input: JobInput):
+    async for batch in self._generate_vllm(...):
+        yield batch  # Batch-level yielding for efficiency
+```
+
+## Extension Points
+
+### 1. **New Model Architectures**
+
+- **Engine Args**: Add new parameters in `engine_args.py`
+- **Compatibility**: Update vLLM argument mapping
+- **Validation**: Add architecture-specific validation
+
+### 2. **New API Features**
+
+- **Engine Extension**: Extend `vLLMEngine` or `OpenAIvLLMEngine`
+- **Input Parsing**: Extend `JobInput` class
+- **Response Format**: Add new response generators
+
+### 3. **Performance Optimizations**
+
+- **Batching Strategy**: Modify `BatchSize` class
+- **Memory Management**: Add new caching strategies
+- **Hardware Optimization**: GPU-specific optimizations
+
+## Security & Best Practices
+
+### 1. **Secret Management**
+
+- **Build Secrets**: Docker secrets for HF tokens
+- **Runtime Secrets**: Environment variable injection
+- **Token Handling**: Secure authentication patterns
+
+### 2. **Resource Limits**
+
+- **Memory Bounds**: Configurable GPU memory limits
+- **Request Limits**: Concurrency and timeout controls
+- **Model Safety**: Trust remote code flags
+
+### 3. **Logging Security**
+
+- **Sanitization**: No secrets in logs
+- **Request Logging**: Configurable request/response logging
+- **Performance Monitoring**: Safe metrics collection
