GPT-5 marks a significant leap in AI-assisted coding, particularly for "vibe coding," where developers use natural language prompts to guide large language models in creating applications. According to Parker Ortolani, GPT-5 surpasses its predecessors, GPT-4o and Claude, in delivering a more complete and refined development experience. While earlier models could generate functional prototypes, GPT-5 offers noticeable improvements in code quality, efficiency, and overall creative control, allowing for a more seamless transition from concept to fully realized application. This advancement promises to democratize app development and empower creators with intuitive AI tools.
