     * [migration guide](https://docs.claude.com/en/api/migrating-from-text-completions-to-messages)
     * for guidance in migrating from Text Completions to Messages.
     *
     * @example
     * ```ts
     * const completion = await client.completions.create({
     *   max_tokens_to_sample: 256,
     *   model: 'claude-2.1',
     *   prompt: '\n\nHuman: Hello, world!\n\nAssistant:',
