BenchCAD Vision2Code (no tools)

Generating executable CadQuery code from multi-view renders, scored by voxel intersection over union on a 1,000-file subset.

How it is run

Section 8.9.2 samples 1,000 of 17,900 Vision2Code files and averages five runs at max effort without external tools. Values use the original 0–1 IoU scale.

What it cannot tell you

Tool-assisted visual verification is a separate configuration. IoU is a similarity score, not an accuracy percentage or a full-dataset run.

Why there is no independent table

No independent suite in this dataset runs BenchCAD Vision2Code (no tools). 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.

BenchCAD Vision2Code (no tools). §8.9.2 / Figure 8.9.2.A: random 1,000-file subset, five max-effort runs, original voxel IoU scale.

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.
