SCIENCE UNDER AUTOMATION

AI in Biological sciences: capabilities and evidence

Biology asks how living systems work across molecules, cells and organisms. An automated assay is one part of establishing a mechanism.

Autonomy · up to 5.5 / 10

Model interval: 3.2–5.5. Assessed 21 October 2026.

Two equally weighted workflow families: a bounded operational task and an investigation or deployment beyond that task. Inherited subfields use this parent scenario.

Calculation and work mix

Each requirement uses the operational scale from 0 (independent execution unestablished) to 4 (reliable independent execution in the stated setting). A workflow takes its lowest requirement level. The two workflows receive equal weight; the headline is 1 + 9 × weighted level / 4.

These levels are source-linked model assignments, not measurements reported by the papers. “Up to” is the upper model bound, not a probability or a forecast date.

Optimize a biological assay in a prepared laboratory: 2–3 / 4.

Discover and independently test a biological mechanism: 0–1 / 4.

Upper bound with 75:25 workflow weights: 6.6. With 25:75 weights: 4.4.

What has AI demonstrated?

A biofoundry couples ML and language models to enzyme design and measurement over four rounds, with fewer than 500 variants per enzyme.

The input sequence and measurable fitness objective are supplied. Two enzyme demonstrations do not establish general organism-level experimental autonomy.

Can AI replace the whole workflow?

The results above measure specific tasks. The field assessment also requires completion of the connected workflow, including the requirements listed here. A field-wide replacement percentage has not been established.
