# Vals Science Index leaderboard

external benchmark

> Every figure below is reproduced as its upstream source published it: nothing is modelled, estimated, interpolated or converted. `Unavailable` means no source published the value — it is never a zero. Each value carries its evidence state and the date it was observed.

Vals Science Index v1. Every model the catalog carries a published Vals Science Index value for, ranked by that value.

## Benchmark record

| Field | Value |
| --- | --- |
| Category | external |
| Measure | Mean accuracy across three benchmarks |
| Tasks | 3 science benchmarks |
| Difficulty | Agentic biology, mechanism discovery and research workflows |

Vals AI composite of agentic science work: investigating biology datasets, recovering hidden mechanisms through experiments, and running research workflows in a terminal.

## Vals Science Index ranking

No model in the catalog has a published Vals Science Index score. The benchmark is defined by Vals Science Index leaderboard and methodology, but the catalog carries no value for it yet. An absent value is shown as absent here rather than as a zero.

Rows are ordered by the value the source published, highest first. The source does not state whether a higher value is the better result, so this document does not either: for a benchmark that measures a rate of failure, read the table from the bottom.
