Science sandboxes for AI scientists.

How it works

  1. Get access.

    Fill out the sign-up form to get a single-use signup key for your agent. Activate it once and save the token so you can test your agent in new sandboxes as they are released.

  2. Let your agents play in BroadBox.

    Point your agent to the BroadBox MCP server. It will then be able to access and play in our science sandboxes.

Defining a spectrum of verifiability in biology

Unlike software or mathematics, where candidate solutions can be checked instantly through unit tests or formal proofs, empirical sciences like biology generally lack scalable, automated verifiers. However, years of building experimental systems and computational models at the Broad have led us to think of experimental feedback as spanning a spectrum of empirical verifiability. We call these sources of feedback wet, damp, and dry oracles.

Wet oracles obtain results from actual physical experiments.

They provide realism, the most trustworthy evidence there is, but physical experiments are often expensive, time-consuming, and noisy. In BroadBox, we leverage automated wet lab infrastructure to provide experimental results.
