In Gradio, you can update the labels of the tabs in a Tabbed layout by modifying the labels of the layout's tabs. Here's how you can update tab labels in Gradio:
```python
import gradio as gr
# Create a function to be displayed in the first tab.
def function_1():
return "This is Tab 1 content"
# Create a function to be displayed in the second tab.
def function_2():
return "This is Tab 2 content"
# Create a Tabbed layout with default tab labels.
layout = gr.Interface(fn=[function_1, function_2], layout="tabbed")
# Set custom labels for the tabs.
layout.layout_set_tab_labels(["Tab 1", "Tab 2"])
layout.launch()
```
In this example, we first create two functions (`function_1` and `function_2`) to be displayed in two different tabs. Then, we create a `Tabbed` layout with default tab labels. To update the tab labels, we use the `layout_set_tab_labels` method and pass a list of custom labels as an argument.
By running this code, you will see a Gradio interface with two tabs, each labeled as "Tab 1" and "Tab 2". You can customize the labels according to your requirements.
