Stores user authentication information\n- Task: Stores task information with all fields we've added\n\nTo use this Flask app with a database backend, you need to set the appropriate database URI in the `app.config['SQLALCHEMY_DATABASE_URI']` variable. For development, you can use SQLite (`sqlite:\/\/\/task_manager.db`), but for production, you can use PostgreSQL (`postgresql:\/\/username:password@localhost\/db_name`).\n\nYou also need to install the required dependencies (`Flask-SQLAlchemy`, `Flask-Migrate`, and `psycopg2-binary` for PostgreSQL).\n\nTo create database migrations, run the following commands:\n\n```\nflask db init\nflask db migrate\nflask db upgrade\n```\n\nThese commands will generate and apply database migrations based on the current state of the database models.","refusal":null,"annotations":null,"audio":null,"function_call":null,"tool_calls":[],"reasoning":null},"logprobs":null,"finish_reason":"stop","token_ids":null}],"service_tier":null,"system_fingerprint":null,"usage":{"prompt_tokens":25632,"total_tokens":27316,"completion_tokens":1684,"prompt_tokens_details":null},"prompt_token_ids":null,"kv_transfer_params":null}
