Why is multimodal low?

The model transported images correctly, but broad visual understanding was never established by the serving qualification. The strongest direct evidence is the PACE visual subset: weak academic-image reasoning and web-screenshot grounding, with only middling visual-puzzle performance.

Eugeny 5.1 is primarily a coding and text reasoning model. Its vision derivative passed a narrow single-image serving gate; that proves the interface works, not that visual reasoning is competitive.

Estimate with caution.

PACE’s multimodal target predictor is the least trustworthy part of this result. On its reference models, its leave-one-model-out diagnostics show almost no useful rank or linear correlation. The 16.93% estimate is directionally consistent with the weak visual proxies, but it should not be treated as Eugeny’s directly measured SWE-bench Multimodal ceiling.

What would settle it? A direct, fidelity-preserving SWE-bench Multimodal run. Until then, 16.93% is a proxy-derived estimate with poor target calibration—not a direct benchmark score.

Run facts.

The full selection finished after one transient LeetCode submission failure was recovered. The identical credentials succeeded on the first retry, ruling out persistent token expiry. Final coverage is complete.
