Definition and comparison boundaryinternal methodology
Can the model reason accurately about difficult scientific material?
Scientific knowledge and reasoning under the benchmark's published question set. Lower is better. Negative log-likelihood for OpenAI's helpful-only Astra checkpoint.
This is a publisher-defined internal evaluation. The task set or grading details are not fully public, so treat it as directional evidence.
OpenAI prints NLL 12.58 for the helpful-only Astra model and 13.13 for ordinary Astra on the same unpublished sequential phage–plasmid evaluation; the indicative threshold is 9.40.
