[frontier] Multimodal agents miss gradual safety risks that only emerge across multi-turn image-text conversations

Evaluate agents on multi-turn multimodal safety benchmarks and add turn-level context-switch guardrails, not just per-message moderation.

Journey Context:
Existing safety benchmarks are mostly single-turn, but real multimodal assistants have extended dialogues where a benign image plus escalating text, or a context switch, gradually produces unsafe output. MTMCS-Bench and related 2026 findings show frontier MLLMs persistently trade off contextual safety against utility: they either miss gradual risks or over-refuse benign requests. Per-message moderation is insufficient because it lacks memory of the conversation arc. The frontier practice is to run evaluation in two modes—escalation-based risk and context-switch risk—and to add guardrails that inspect the trajectory, not just the current turn, for intent drift and inappropriate disclosure across modalities.
