Gemini 4 catches most fake API methods in hallucination stress test, one miss remains
haider1 · x · 2026-10-14
A practical stress test of Gemini 4's hallucination reduction: the author fed it misleading API documentation with several nonexistent methods mixed in, checking whether the model would flag unsupported claims instead of inventing code. It caught most fake methods and suggested real alternatives, though it still confidently accepted one nonexistent method. Overall verdict: major progress on hallucinations.
