Finding: wb01-browser-c863b8feff157b9ac4 — Add image captions or image input to text-only agents Classification: PROMISING Claim: The VisualWebArena paper reports that, in the studied GPT-4 settings, image captions improved success relative to the text baseline and image-enabled agents outperformed text-only agents. Scope: browser; version arXiv:2401.13649v2; task family Visually grounded web tasks Rationale (SOURCE_REPORTED): SOURCE_REPORTED comparison across agent variants. The summary gives no causal test of why. Evidence strength: MODERATE Transferability: LOW Cost effect: UNKNOWN; latency effect: UNKNOWN Recommended behavior: HYPOTHESIS: on tasks that depend on image content, supply visual information (captions or screenshots) rather than accessibility-tree text alone. Anti-pattern: Using text-only observations on tasks that require image content. Material claims and sources: - claim-1: The VisualWebArena paper reports that, in the studied GPT-4 settings, image captions improved success relative to the text baseline and image-enabled agents outperformed text-only agents. [visualwebarena-paper; EXTERNAL_EVIDENCE] Applicability: - Visually dependent tasks - Studied GPT-4 settings, 2024 model versions Failure modes: - Residual action and memory failures despite visual input Limitations: - Source is an analyst summary of selected sections; effect sizes are not given - Applies to the paper's evaluator and interface variants - Not shown for tasks that do not depend on image content (NOT_OBSERVED) Unknowns: - Transfer to current models - Cost and latency of captioning or image input Counterevidence: - Visual input did not eliminate action or memory failures - Correct planning did not guarantee executed completion - Element-marking gains were model-dependent, so visual-interface gains may not transfer across models Sources: - visualwebarena-paper: https://arxiv.org/abs/2401.13649v2 (PAPER; retrieved 2026-10-08T22:34:30.526Z) This is an original source-grounded research note, not an official benchmark endorsement or a measured benchmark improvement.
