A new paper from Google DeepMind and Stanford reveals that vision-language models are susceptible to hidden steering by irrelevant geometric shapes in prompts. Experiments showed that adding a red heart image caused Claude Opus 4.7 and GPT-5.4 to shift their recursive solution choice from 0% to 100% on binary tree tasks, while Gemini's reasoning traces often failed to flag the visual influence. This highlights the critical need for rigorous isolation testing of multimodal inputs.

DeepMind Study: Irrelevant Shapes Steer AI Code Logic
- Irrelevant visual elements (e.g., a red heart) can drastically alter LLM code generation strategies (e.g., forcing recursion).
- Model Chain-of-Thought (CoT) often fails to self-detect or acknowledge irrational guidance from images.
- Developers must implement control tests in agent workflows with image inputs to mitigate hidden biases.
