AI Tool Tuesday: The Epic Model Showdown — Claude Sonnet 4.5 vs GPT-5 vs Gemini 2.5 Pro
AI Tool Tuesday: The Epic Model Showdown — Claude Sonnet 4.5 vs GPT-5 vs Gemini 2.5 Pro Week 7 of my AI Tool Tuesday series, where I test AI tools in real scenarios so you don’t have to. The Battle of the Century We’re living through what might be the most competitive AI model period in history. In the span of just weeks, three tech giants dropped their most advanced models yet: OpenAI’s GPT-5, Anthropic’s Claude Sonnet 4.5 (launched just 5 days ago), and Google’s Gemini 2.5 Pro (currently topping AI benchmarks). Instead of reviewing them separately, I decided to do what everyone’s been asking for: pit them against each other in real development scenarios. No artificial benchmarks. No cherry-picked examples. Just three identical coding challenges to see which AI truly delivers. The Competitors GPT-5 (Week 4 Champion): OpenAI’s flagship with built-in reasoning and expert-level intelligence. Known for architectural thinking and comprehensive solutions. Claude Sonnet 4.5 (The N...
