From 1329e874a49154b3c46ff08a8329d7392195fc0c Mon Sep 17 00:00:00 2001 From: DustyWalker Date: Tue, 5 Aug 2025 18:23:18 +0200 Subject: [PATCH] feat(worker): implement AI vision services and complete image processing pipeline MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add real OpenAI GPT-4 Vision integration with rate limiting - Add real Google Cloud Vision API integration - Create vision service orchestrator with fallback strategy - Implement complete image processing pipeline with BullMQ - Add batch processing with progress tracking - Create virus scanning processor with ClamAV integration - Add SEO filename generation with multiple strategies - Include comprehensive error handling and retry logic - Add production-ready
