OpenAI unveils GPT-5 with faster speed, greater utility, broader accessibility, and a redesigned ChatGPT interface that adds expanded customization and voice features.

The standout feature is 'vibe coding,' where users describe the desired software in natural language and the AI generates the code and applications.

GPT-5 introduces 'agentic coding,' enabling programs to run in the background with less user oversight.

Live demonstrations showcased a French language-learning app with a Snake-style pronunciation game, producing hundreds of lines of code in minutes.

Mashable tested GPT-5 with a Titanic visualization and interactive timeline, and GPT-5 delivered a compelling visualization while GPT-4 lagged.

Natural language could become the dominant paradigm for coding, though prompts may require refinement and results can contain bugs.

OpenAI system cards and independent evaluations will be important benchmarks, with Claude still cited as a competitor in coding proficiency.
