AEC-Bench (Nomic Tools) - Cross-Reference Resolution: leaderboard
Metric: Mean reward (0-100) from the task verifier on the 51 cross-reference-resolution instances (finding cross-references that do not resolve to valid targets) built from real public-sector construction documents, one trial per instance, where the agent runs in its coding-agent harness (Codex for GPT, Claude Code for Claude) augmented with Nomic Parse and Nomic Embeddings structured drawing representations; higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 4 models tracked.
