  • It should load without errors, confirming a successful installation.

Running Tests to Confirm the Model Is Operational

Using the API documentation, run test commands against endpoints such as /v1/engines/copilot-codex/completions or /v1/completions with a sample request body, for example:

{
  "prompt": "\n\n### Instructions:\nWhat is the capital of France?\n\n### Response:\n",
  "stop": ["\n", "###"]
}

and verify that the response body returns the expected result, for example:

{
  "text": "The capital of France is Paris.",
  "index": 0
}

Integrating with Other Tools or Platforms

Using the provided API documentation, build integration components in your web application that send prompts to Llama 2 and receive responses - remember to handle rate limits and error messages appropriately.
