Descriptions:
Skill Leap AI takes ChatGPT 5.5 through a set of practical, real-world tests on the day of its release, deliberately skipping trivial prompts in favor of tasks relevant to everyday work. The video examines whether the new model can build functional web apps from HTML, debug its own errors without hand-holding, and deliver a meaningfully improved experience over previous GPT generations.
The host runs identical prompts in both ChatGPT 5.5 and Claude Opus 4.7, including a 3D city builder modeled on SimCity and an interactive photorealistic Earth visualization. Claude Opus 4.7 produced a working city builder on the first attempt; ChatGPT 5.5 required a bug-fix pass before delivering a functional result — though its final output is rated more feature-rich. The video also explains GPT 5.5’s thinking modes (standard, extended, and heavy), showing how switching from standard to extended thinking immediately resolved generation errors on the Earth visualization task.
Availability and pricing are covered briefly: GPT 5.5 is rolling out to Plus, Pro, Business, and Enterprise accounts on launch day, with API access pending. OpenAI notes the model is priced higher per token than GPT-5.4 but is more token-efficient, potentially offsetting the cost increase. The video closes with a mention of ChatGPT’s new workflow agents platform, which the host plans to cover separately. A useful first-look for anyone deciding whether to migrate production workloads from earlier OpenAI models or from Claude.
