This document applies to the intelligence classification of various types of terminals, and also provides a reference for the design, development, application, selection and testing of terminals. 2 Normative References The following document is essential for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies. GB/Z 177.1 Artificial intelligence terminal intelligence classification — Part 1: Reference framework 3 Terms and Definitions For the purposes of this document, the terms and definitions given in GB/Z 177.1 and the following apply. 3.1 testing scenario A comprehensive test context set for testing the key capabilities of a terminal in a specific application scenario. 3.2 testing task A basic execution unit in terminal intelligence testing. NOTE: A testing task can serve either as a specific step within a testing scenario or as an independent, atomic test item to be completed separately. 3.3 scenario context A dynamic set of information about the user, device and environment, constructed in real time by a terminal to accurately understand and respond to a user’s intent when executing a specific task. 3.4 endtoend closedloop The complete process from when a user issues an instruction or intent, through the terminal performing the necessary steps of perception, cognition and execution, to the successful delivery of the task result. 3.5 personal knowledge base A collection of personalised information about a specific user, such as facts, relationships, preferences and habits, that is learned and stored by a terminal with the user‘s authorisation during longterm use. 3.6 session An interaction process between a user and a terminal to complete one or a set of related tasks. 3.7 session context A set of dynamic information, recorded and maintained during a session, including the interaction history and current state within that session, to ensure interaction continuity and accurate task execution. 3.8 ability element A basic category that forms the toplevel framework of a terminal’s intelligence capabilities. 3.9 task decomposition The ability of a terminal to automatically break down a complex user intent or a multistep instruction into a series of smaller, more specific and executable subtasks. 3.10 task orchestration The ability, based on task decomposition, to plan and generate an optimal or reasonable execution sequence according to the logical relationships, dependencies and execution priorities among subtasks. 3.11 intent clarification The ability of a terminal, when it recognises that a user‘s intent is unclear, to further clarify the user’s true need by actively asking questions, providing options or requesting additional information. 4 Abbreviations The following abbreviation applies to this document. TTS: TexttoSpeech 5 Overview Based on the complexity and degree of automation of the various tasks a terminal can perform within its functional scope, the terminal‘s intelligence level is classified into four levels, namely Level 1 (L1) to Level 4 (L4). The higher the level, the higher the terminal’s intelligence level. Higherlevel terminals encompass all the capabilities of lowerlevel terminals. For example, an L3level terminal shall possess all the key capabilities of both L1 and L2 levels. 6 Classification Levels 6.1 L1 Response Level The terminal can understand a single simple instruction, invoke a specific tool according to the instruction, and complete a singlestep task. 6.2 L2 Tool Level The terminal can understand user instructions and simple intents, and has simple reasoning capabilities. It has the ability to invoke preset tools to complete singlestep or clearly defined multistep tasks. It has the ability to generate content in at least one modality, such as text, audio or images. It has shortterm memory within a single session. 6.3 L3 Assistance Level The terminal can comprehensively understand user instructions and intents, and has the ability to actively clarify intents. It has strong reasoning capabilities and can automatically perform task decomposition and task orchestration. It has the ability to dynamically select and automatically invoke tools, and to generate content in at least one modality, such as text, audio or images. It has both shortterm and longterm memory capabilities. 6.4 L4 Collaboration Level To be determined. NOTE: Based on the current state of technological development, this document specifies the key intelligence capabilities for Levels L1 to L3. The classification for Level L4 and above will be defined and refined in subsequent revisions of this document. 7 Capability Elements 7.1 Primary capability elements 7.1.1 Perception The ability of a terminal to acquire data from sensors, system services and application services through internal/external sensors, data acquisition modules and recognition modules, and to construct the scenario context information required for task execution, including user information perception, device information perception and environmental information perception. 7.1.2 Cognition The ability of a terminal to understand user intents and related information, to perform reasoning and analysis on information, and to dynamically plan tasks, ensuring that task execution meets the user’s expected goals. This includes understanding, reasoning and planning. 7.1.3 Execution The ability of a terminal to generate responses based on the output of the cognitive process and to invoke internal/external tools and services to achieve task goals. This includes tool invocation, content generation, interconnection and collaboration, and expression output. 7.1.4 Memory The ability of a terminal, with the user‘s authorisation, to extract, store, retrieve and dynamically update interaction content and related information. This includes shortterm memory and longterm memory. 7.1.5 Learning
