 `generate.py` by default runs a gradio server, which also gives access to client API using gradio client.  See example [test code](client_test.py) or other tests in our [tests](https://github.com/h2oai/h2ogpt/blob/main/tests/test_client_calls.py).  Any element in [gradio_runner.py](gradio_runner.py) with `api_name` defined can be accessed via the gradio client.
 
+#### Python Client Library
+
+An OpenAI compliant client is available. Refer the [README](client/README.md)  for more details.

 #### Python Wheel
 
 The wheel adds all dependencies except specialized dependencies like 4-bit and flash-attention.  For GPU build do:

+# h2oGPT Client
+A Python thin-client for h2oGPT.
+
+## Usage
+```python
+from h2ogpt_client import Client
+
+client = Client("http://0.0.0.0:7860")
+
+# text completion
+response = client.text_completion.create("Hello world")
+response = await client.text_completion.create_async("Hello world")
+
+# chat completion
+chat_context = client.chat_completion.create()
+chat = chat_context.chat("Hey!")
+print(chat["user"])  # prints user prompt, i.e. "Hey!"
+print(chat["gpt"])   # prints reply of the h2oGPT
+chat_history = chat_context.chat_history()
+```
+:warning: **Note**: Client APIs are still evolving. Hence, APIs can be changed without prior warnings.
