-# OpenAI Compatible PyWorker
-
-This is the base PyWorker for OpenAI compatible inference servers.  See the [Serverless documentation](https://docs.vast.ai/serverless) for guides and how-to's.
-
-## Instance Setup
-
-1. Pick a template
-
-This worker is compatible with any backend API that properly implements the `/v1/completions` and `/v1/chat/completions` endpoints.  We currently have three templates you can choose from but you can also create your own without having to modify the PyWorker.
-
-- [vLLM](https://cloud.vast.ai/?ref_id=62897&creator_id=62897&name=vLLM%20%2B%20Qwen%2FQwen3-8B%20(Serverless)) (recommended)
-- [Ollama](https://cloud.vast.ai/?ref_id=62897&creator_id=62897&name=Ollama%20%2B%20Qwen3%3A32b%20(Serverless))
-- [HuggingFace TGI](https://cloud.vast.ai/?ref_id=62897&creator_id=62897&name=TGI%20%2B%20Qwen3-8B%20(Serverless))
-
-
-All of these templates can be configured via the template interface.  You may want to change the model or startup arguments, depending on the template you selected.
-
-2. Follow the [getting started guide](https://docs.vast.ai/serverless/getting-started) for help with configuring your serverless setup.  For testing, we recommend that you use the default options presented by the web interface.
-
-## Client Setup (Demo)
-
-1. Clone the PyWorker repository to your local machine and install the necessary requirements for running the test client.
-
-```bash
-git clone https://github.com/vast-ai/pyworker
-cd pyworker
-pip install uv
-uv venv -p 3.12
-source .venv/bin/activate
-uv pip install -r requirements.txt
-```
-
-## Using the Test Client
-
-Several examples have been provided in the client to help you get started with your own implementation.
-
-### Completions
-
-Call to `/v1/completions` with json response
-
-```bash
-python -m workers.openai.client -k <API_KEY> -e <ENDPOINT_NAME> --completion --model <MODEL_NAME>
-```
-
-### Chat Completion (json)
-
-Call to `/v1/chat/completions` with json response
-
-```bash
-python -m workers.openai.client -k <API_KEY> -e <ENDPOINT_NAME> --chat --model <MODEL_NAME>
-```
-
-### Chat Completion (streaming)
-
-Call to `/v1/chat/completions` with streaming response
-
-```bash
-python -m workers.openai.client -k <API_KEY> -e <ENDPOINT_NAME> --chat-stream --model <MODEL_NAME>
-```
-
-### Tool Use (json)
-
-Call to `/v1/chat/completions` with tool and json response.
-
-This test defines a simple tool which will list the contents of the local pyworker directory.  The output is then analysed by the model.
-
-```bash
-python -m workers.openai.client -k <API_KEY> -e <ENDPOINT_NAME> --tools --model <MODEL_NAME>
-```
-
-### Interactive Chat (streaming)
-
-Interactive session with calls to `/v1/chat/completions`.
-
-Type `clear` to clear the chat history or `quit` to exit.
-
-```bash
-python -m workers.openai.client -k <API_KEY> -e <ENDPOINT_NAME> --interactive --model <MODEL_NAME>
-```

-# <INFERENCE_SERVER> + <MODEL_NAME> (serverless)
-
-Run <INFERENCE_SERVER> with our serverless autoscaling infrastructure.
-
-See the [serverless documentation](https://docs.vast.ai/serverless) and the [Getting Started](https://docs.vast.ai/serverless/getting-started) guide for in-depth details about how to use these templates.
-
-## Configuration
-
-Two environment variables are provided to help you configure the <INFERENCE_SERVER> server:
-
-| Variable | Default Value | Used For |
-| --- | --- | --- |
-| `MODEL_NAME` | `<MODEL_NAME>` | The model to load.  Also accepts [hf.co/repo/model](#) links |
-| `<ARGS_VAR>` | `<ARGS_VAL>` | Arguments to pass to the `<ARGS_RECEIVER>` command |
-
-This template has been configured to work with <MIN_VRAM> VRAM. Setting alternative models and server arguments will change the VRAM requirements. Check model cards and <INFERENCE_SERVER_DOCS> for guidance.
-
-## Usage
-
-We have provided a demonstration client to help you implement this template into your own infrastructure
-
-### Client Setup
-
-Clone the PyWorker repository to your local machine and install the necessary requirements for running the test client.
-
-```bash
-git clone https://github.com/vast-ai/pyworker
-cd pyworker
-pip install uv
-uv venv -p 3.12
-source .venv/bin/activate
-uv pip install -r requirements.txt
-```
-
-### Completions
-
-Call to `/v1/completions` with json response
-
-```bash
-python -m workers.openai.client -k <API_KEY> -e <ENDPOINT_NAME> --completion --model <MODEL_NAME>
-```
-
-### Chat Completion (json)
-
-Call to `/v1/chat/completions` with json response
-
-```bash
-python -m workers.openai.client -k <API_KEY> -e <ENDPOINT_NAME> --chat --model <MODEL_NAME>
-```
-
-### Chat Completion (streaming)
-
-Call to `/v1/chat/completions` with streaming response
-
-```bash
-python -m workers.openai.client -k <API_KEY> -e <ENDPOINT_NAME> --chat-stream --model <MODEL_NAME>
