Build resilient Playwright AI agents with comprehensive error handling for timeouts, missing elements, navigation failures, and network errors, plus retry decorators and graceful degradation strategies.
Learn how to capture web page screenshots and send them to GPT-4 Vision for element identification, layout understanding, and structured analysis that powers browser automation agents.
Build a complete screenshot-action loop where GPT-4V analyzes web pages, decides where to click, and navigates autonomously. Learn coordinate extraction, click targeting, and navigation decision-making.
Discover how GPT Vision identifies interactive web elements visually, eliminating the need for CSS selectors or XPaths. Learn bounding box extraction, OCR-free text reading, and visual element classification.
Compare GPT Vision and DOM parsing for browser automation. Learn when visual understanding outperforms HTML analysis, how to build hybrid approaches, and a practical decision framework for choosing the right method.
Build an AI agent that uses GPT Vision to detect form fields, understand their purpose, map values to the correct inputs, and verify successful submission — all without relying on CSS selectors.
Implement visual regression testing using GPT Vision to detect UI changes, classify their severity, and generate human-readable reports. Move beyond pixel-diff tools to semantic understanding of visual changes.
Use GPT Vision to perform automated accessibility audits that detect visual WCAG violations including contrast issues, missing labels, touch target sizes, and reading order problems — generating actionable compliance reports.
