Jiuzhang Large Model (MathGPT)

What is the large-model MathGPT with nine chapters?

MathGPT, the large-scale model developed by Good Future Education Group, is an educational model designed for use in mathematics problem-solving and explanation. It is intended for learners, educational institutions, and research purposes. The current product portfolio includes information on this large-scale model and related research findings, the consumer-oriented application Nine Chapters Love Learning, as well as enterprise solutions provided through Good Future’s AI open platform.

Jiuzhang Aixue serves as a more straightforward access point for ordinary users, offering services such as photo-based question answering, guided explanations of problems, assignment grading, and personalized practice exercises. Corporate clients can request additional functions like problem solving and grading, which can be used as aids for lesson preparation, to answer students’ questions, and to integrate into teaching tools.

Product composition and current status

Main functions

Socratic AI lecture style

• After the user takes a photo of the problem or uploads it, the system identifies the question and provides interactive explanations; it is suitable for dealing with problems for which one does not know how to proceed or only understands some of the steps involved.
• The Teacher Xiao Si approach does not simply provide the final answer; instead, it guides the user by posing successive questions to help them analyze the conditions, choose the appropriate methods, and carry out the reasoning process.
• The Teacher Xiao Zhi mode breaks down the complete solution into key steps, allowing users to ask further questions about the parts where they get stuck; it is suitable for learners who wish to identify the problem quickly.
• Video explanations of key concepts are used to supplement those concepts and methods, but the content generated and the identification results still need to be verified by referring to textbooks, teachers, or standard answers.

General photography inquiries, answers to questions, and assignment grading

• Current mobile apps support taking photos of entire pages, and they can be used to grade assignments and answer questions in subjects such as Chinese, English, mathematics, physics, and chemistry.
• The input can be assignments, test papers, or photos of individual questions; the system first identifies printed text, handwritten content, and formulas, and then provides the judgment result along with an explanation.
• The grading results, together with the standard answers, the reasoning behind the solutions, and video explanations, can help students identify the incorrect steps, rather than merely showing whether a response is correct or not.
• The quality of the images, the handwriting, any obstructions in the layout, as well as the type of questions and the academic context all affect the accuracy of recognition and scoring; important exam questions should be checked manually.

AI-driven targeted practice and error management

• AI Precision Training diagnoses the weak areas based on performance during practice, and recommends appropriate exercises of suitable difficulty levels for daily reinforcement or preparation for exams.
• The function for organizing incorrect questions helps users save the questions that need to be reviewed; together with the capabilities for erasing and printing test papers, it enables the creation of materials for further practice.
• Personalized recommendations rely on the learning data stored in the account; changing the account number, having insufficient data, or errors in question recognition can affect the diagnostic results.

Multimodal virtual classrooms and AI companionship

• The mobile application offers a multimodal virtual classroom with annotations and highlights, enabling the explanation process to focus on the key aspects of the topic.
• The AI companion feature is intended for everyday interaction and learning purposes, and it should not replace teachers, guardians, or professional psychological support.
• The app also includes features related to the campus; the specific access points and availability may vary depending on the version, grade level, account status, or region.

Corporate problem-solving solutions

• Enterprise users can submit photos or text of the questions, and in return they will receive suggestions on how to solve them, step-by-step solutions, an overview of the knowledge points involved, and a summary of the skills required.
• The solution covers various question types from multiple K12 subjects, and integrates capabilities such as OCR, formula recognition, handwriting recognition, as well as the separation of printed text from handwritten text.
• The identified questions can be categorized by topic, and used for searching for questions, recommending similar questions, assisting teachers in lesson preparation, or providing a platform for students to get answers to their queries.
• The company page offers trial versions and consultation services for partnerships; the scope of applications, concurrency levels, response times, and service guarantees in the production environment are to be determined as per the contract.

Enterprise grading solutions

• The system allows enterprises to review photos of assignments or tests, provides the results for each question, and can also include explanations of how to solve the questions, the correct answers, as well as video tutorials.
• The teacher platform enables the processing of batch assignments and the generation of learning analyses, while the student version offers immediate corrections and additional practice exercises.
• Complex handwriting, open-ended questions, multiple-answer questions, and subjective questions still carry a risk of misjudgment; therefore, automatic grading cannot be used as the sole basis for assessment.

Chapter 9: Tutorial on Using Aixue

1. Choose between the iPhone, iPad, Android installation packages or WeChat mini-programs based on your device; before installing, verify the app name and its provider.
2. Register or log in to your account; minors should read the terms of service, privacy policy, and rules regarding child information under the supervision of a guardian.
3. When shooting individual questions, entire pages of assignments, or test papers, ensure even lighting and a complete image, while trying to avoid wrinkles, shadows, and finger obstructions.
4. Check the topics and subjects identified by the system, then choose between guided explanation, key steps, page-wide correction, or targeted practice.
5. First, think independently about the questions posed by the system, then check the next set of instructions; if there are issues with formulas, units, conditions, or answers, take another photo.
6. Include the representative wrong answers in a collection of such errors, carry out targeted practice, and verify the key conclusions using the textbook, the teacher’s guidance, or the standard answers.

Input, output, and applicable tasks

Supported platforms

Prices, trials, and refunds

Free download does not mean that all features will remain free forever; the exact amount and limits associated with premium membership are not made public for consumer users. Free use or trials on the corporate page also do not imply unlimited access for production purposes; it is necessary to check the account settings and the contract before starting use.

• For paid services, a payment reminder will be displayed before purchase; the price, duration, and benefits are subject to those indicated on the actual settlement page.
• Unless the product has major defects, the platform breaches its obligations significantly, the agreement provides otherwise, or legal requirements apply, refunds are generally not granted after payment without a valid reason.
• Purchased content or services should be used within their respective expiration periods; unused rights after that time generally cannot be refunded in cash.

APIs, SDKs, and enterprise integration

1. Register an account on the Good Future AI Open Platform to view the currently available services for solving problems, grading assignments, and other related educational functions.
2. Read the access guide and API documentation, create an application as required, obtain the necessary credentials, and implement signature-based authentication.
3. Use masked text or image questions to verify recognition, problem-solving, and grading results, while keeping track of failure rates for different subjects and question types.
4. Confirm with the business team the free quota, QPS, concurrency levels, pricing, data processing capabilities, content licensing rules, service guarantees, and compliance requirements regarding minors.
5. Before going live, implement manual review, error handling, log anonymization, permission isolation, and credential rotation to prevent the model’s outputs from being used directly as the final scores.

The presence of API documentation on the open platform does not mean that all the functions provided by 9Chapter can be used without any restrictions, nor does it imply that the benefits associated with a 9Chapter account can be converted into API credits. As of now, there is no official list of SDKs specific to 9Chapter; developers should refer to the documentation available in their accounts.

Open-source status and research resources

TAL-SCQ5K is available in both Chinese and English versions; each version contains 5,000 multiple-choice questions on math competitions along with detailed solutions, and these questions are categorized by grade level – elementary school, middle school, and high school. The fact that the dataset or assessment tools are open source cannot be equated to the open sourcing of the JiuZhang large model.
