The video tests GPT-5.6 and Claude 3.5 Opus side-by-side to build a full-stack e-commerce app with stock management. It compares UI aesthetics, feature completeness, error handling, and weekly usage limits. The creator shares pros and cons of ChatGPT Pro vs Cloud Max plan for daily coding.
A short editorial from the VEONIB team on why this content matters.
GPT-5.6 creates attractive UIs but misses features and uses more tokens; Claude Opus is reliable and efficient. Trade-off between aesthetics and reliability.
Real-world token usage per app provides a concrete comparison; SEONIB advises verifying all critical features, especially with GPT-5.6.
Choose Cloud Max for production code; ChatGPT Pro for UI-heavy MVPs, but budget extra time for bug fixes.
OpenAI's advanced language model, known for creative UI design but higher token usage.
Anthropic's model focused on reliable, precise code with lower token consumption.
OpenAI's premium subscription with increased usage limits and access to Codex.
Anthropic's top-tier plan offering higher limits, Fable 5, and Cloud Design tools.
Application with frontend, backend, admin panel, and payment integration built via AI.
Weekly or hourly cap on AI model interactions affecting productivity.
OpenAI's coding agent interface for using GPT models in development.
Anthropic's coding environment integrated with Claude models for app building.
Which AI model is better for full-stack e-commerce apps?
GPT-5.6 offers better UI but misses some features; Claude 3.5 Opus is more reliable but boring. Depends on priority.
How much weekly usage does GPT-5.6 consume?
In the test, building one full-stack app used 9% of the weekly limit on high effort.
How does Claude 3.5 Opus usage compare?
Same app used only 4% of weekly limit on extra high effort.
What is the main disadvantage of GPT-5.6?
It sometimes misses critical features (e.g., missing payment proof view) and over-adds unnecessary extras, increasing token cost.
Why does the creator prefer Cloud Max plan for daily coding?
Better weekly limit management, more predictable consumption, and access to Fable 5 for complex tasks.
Which subscription includes image generation tools?
ChatGPT Pro includes GPT Image 2, while Cloud Max includes Cloud Design for UI/PPT creation.
Can ChatGPT Pro's codex be used in other agents?
Yes, the Codex subscription can be used with third-party agents like Hermes Agent and Open Cloud.
What is the Fable 5 model mentioned?
A high-capability model from Cloud (likely Claude Opus variant) with higher token price but better performance.
Does Claude Opus require more UI prompting?
Yes, because its UI is generic and less intuitive, requiring additional prompts to improve aesthetics.
Which plan is recommended for enterprise-level apps?
Cloud Max plan with Claude Opus or Fable 5 for reliability and functional completeness.
