Morphology-to-molecule matching

Matching four sets of multi-channel liver-cell images to their shuffled molecule-dose perturbations in Axiom Bio’s assay.

How it is run

Section 8.13.2 reports matching accuracy, generally averaged over five attempts per problem at max effort, with Haiku biology safeguards disabled.

What it cannot tell you

Four-way matching has a 25% chance baseline. This assay-specific figure is separate from general biomedical image analysis and medicinal chemistry.

Why there is no independent table

No independent suite in this dataset runs Morphology-to-molecule matching. The numbers below are the ones model publishers report about their own models, which is a different kind of evidence: each publisher chooses its own harness and effort level, so a row is readable on its own and not against the other rows.

Morphology-to-molecule matching. §8.13.2: four-way matching of liver-cell images to molecule-dose perturbations. Haiku biology safeguards off.

Section 8, pages 111–139 of the Haiku 5.5 system card, read 8 October 2026. Values come from exact prose, tables and labelled figures. Unless specified, Haiku uses adaptive thinking at max effort and five trials with evaluation-specific context up to 1M. Each row retains its subset, metric, effort and source notes; no score is assigned to an unspecified SWE-Bench Pro version. Terminal runs use safeguards without fallback and no internet egress. ProgramBench uses filtered tasks and hidden-test pass rate without a time limit. OSWorld partial and strict results use the official 82-task offline subset. CAD uses 0–1 voxel IoU. Healthcare raw and length-adjusted scores stay separate. Life-science results disable Haiku biology safeguards. Independently run figures quoted by Anthropic remain publisher reports here. Missing comparison values are not inferred from rounded charts.
