I tested Gemini, ChatGPT, and Claude on simple 5th-grade geometry worksheets. Claude delivered perfect, consistent results across both tests, while Gemini and ChatGPT stumbled on triangles. ChatGPT recovered after a retry, but Gemini doubled down on errors. The takeaway: AI can solve geometry, but reliability is still a real issue.

Can AI handle basic math? I tested ChatGPT, Gemini, and Claude on 5th-grade word problems. All three delivered perfect results—accurate answers, clear explanations, and zero errors. A simple test. Results can still vary

Simple AI image test: ChatGPT, Claude, Grok, and Gemini all given the exact same prompt with no optimization. The differences were striking from cartoonish interpretations to near-photorealistic scenes revealing each model’s instincts, strengths, and blind spots right out of the box.

The Tester AI scoring explained: At The Tester AI, every test is built around a simple principle: Can AI actually do the job—not just in theory, but in practice? Each test is evaluated across five core categories, scored on a scale of 1 to 5: Output Delivered – Did the AI complete the task? Accuracy – How correct was the result? Quality – Is the output usable in a real-world setting? Ease of Use – How much effort, prompting, or iteration was required? Reliability – Was the be
