Fwiw the two models that did have access to search disagreed with each other on the bombing one:

> 7.1 Model selection

> Five frontier models, chosen to cover two capability surfaces:

> Parametric (training-only): GPT-5.4 (OpenAI), Claude Opus 4.7 (Anthropic), Gemini 3 Pro (Google)

> Retrieval-augmented: Gemini 3 Pro + Search (Google), Sonar Pro (Perplexity)
