Section 01

[Introduction] Full-Stack Exploration of OpenAI's Multimodal AI: Agent Workflow Practice with GPT, DALL-E, and Sora

This open-source project systematically explores OpenAI's generative AI ecosystem, integrating three major modalities: GPT (reasoning orchestration), DALL-E (image generation), and Sora (video creation), to build autonomous Agent workflows and realize an end-to-end creative pipeline, demonstrating the value and practical path of multimodal AI integration.

Section 02

The Multimodal Era of Generative AI and Project Background

Generative AI has evolved from single text generation to covering multimodal creation, and OpenAI has built a product matrix including GPT (language reasoning), DALL-E (image generation), and Sora (video creation). However, using tools individually can only complete isolated tasks; the project aims to explore methods to connect them into an autonomous Agent workflow.

Section 03

Integration of Three Modalities and Core Methods of Agent Workflow

The project deeply integrates three modalities: GPT serves as the workflow brain (understanding intent, decomposing tasks, generating prompts); DALL-E handles visual creation (keyframes, concept maps); Sora advances dynamic video generation. The Agent workflow includes four key links: task decomposition, prompt optimization, quality evaluation iteration, and cross-modal coordination.

Section 04

Key Points of API Integration Engineering Practice

The project demonstrates API interaction practices: rate limit management (request queue, backoff strategy); cost control (estimation and budget mechanism); error handling and degradation (automatic retry or degradation in case of failure).

Section 05

Practical Application Scenarios of Multimodal Agent Workflow

Application scenarios include: content creation automation (complete content packages for self-media); product design prototyping (natural language to visual prototypes); educational content production (knowledge points to teaching materials); batch production of marketing materials (brand-adapted multimedia).

Section 06

Current Challenges and Ethical Considerations

Challenges include model coordination consistency bias and insufficient transparency in Agent decision-making; ethical aspects involve discussions on copyright ownership and creative ethics.

Section 07

Conclusion: Future Directions of Multimodal AI Creation

The project provides a starting point for understanding multimodal AI trends. Although there is still a distance from fully automated creation, the idea of integrating GPT, DALL-E, and Sora points to the future direction of content creation.
