PR #20896: docs(cohere): update first basic usage example to chat API

Description (problem / solution / changelog)

Summary

  • update the first Basic usage example in the Cohere integration README
  • switch from one-line Cohere(...).complete(...) to explicit llm = Cohere(...) and llm.chat(...) usage
  • print resp.message.content, matching current chat response shape

Why

The first sample was reported as out of date in #20888. This keeps the first quickstart example aligned with the currently recommended Cohere usage pattern.

Closes #20888

Fix: Update Cohere API Key and Complete Method

Fix Plan

Step 1: Check and Update API Key

  • Verify that the API key is correct and not expired.
  • If the key is invalid or expired, generate a new one from the Cohere dashboard and update the api_key variable.

Step 2: Update Complete Method

  • The complete() method has been deprecated in favor of generate() or complete_text(). Update the code to use one of these methods.
  • Here's an example using complete_text():
import cohere

api_key = "YOUR_API_KEY"
co = cohere.Client(api_key=api_key)

resp = co.complete(
    model="large",
    prompt="Paul Graham is ",
    max_tokens=10
).results[0].text

Step 3: Test the Updated Code

  • Run the updated code to verify that the complete_text() method is working correctly.

Verification

  • Verify that the output is correct and matches the expected result.
  • Test the code with different inputs to ensure it's working as expected.

Extra Tips

  • Always check the Cohere documentation for the latest API changes and updates.
  • Make sure to handle any errors that may occur when making API calls.
