IBA-Bench - Daily Consumption: leaderboard

IBA-Bench (Song et al., 2026) tests whether an LLM agent completes a task while honoring user preferences that are only implicit in a long, noisy interaction history, here in the daily consumption domain. Models answer from bge-m3 retrieved history chunks, and the score is the percentage of hidden preference checkpoints the final text or API call satisfies, averaged over three LLM judges; higher is better.

Metric: Checkpoint satisfaction (%; share of hidden preference checkpoints satisfied by the final action, daily consumption domain; mean of three LLM judges: DeepSeek-V3.2, Qwen3-4B-Instruct and Qwen3-30B-A3B-Instruct; retrieval-augmented baseline with bge-m3 top-3 chunks). Source: arxiv.org. Saturation forecast: Estimated already saturated. 10 models tracked.
