Benchmarks
Independent benchmark results
Scores come from independent evaluators that ran the model themselves, pinned to a dated snapshot. Rank is among current models in the same snapshot. OpenAI's own launch figures are in the next section, because they are not measured the same way.
No independent benchmark has published a result for GPT-Rosalind-6 yet. It is still compared below on price, context and capabilities.

OpenAI's life sciences evaluations at the highest reasoning budget it tested. OpenAI compares them only with GPT-Rosalind-5.5, which is not in this catalog: 28.9%, 16.7% and 44.0% on the same problem sets.
Fit
Strengths, cautions and best uses
- Strengths
- OpenAI's reasoning model for biology, drug discovery and translational medicine, on the same weights as GPT-6 Astra but with fewer refusals on dual-use biology questions
- OpenAI reports 49.6% on MedChemBench v7, 37.7% on GeneBench Pro v13 and 61.3% on LifeSciBench Gold at its highest reasoning budget, up from 28.9%, 16.7% and 44.0% for GPT-Rosalind-5.5
- $15 input, $75 output and $1.50 cached input per 1M tokens, 1.5 times the price of GPT-6 Astra
- Cautions
- Limited access: OpenAI offers it only through its trusted-access program, after reviewing each applicant's intended use, security controls and governance, for internal research
- OpenAI treats it as High capability in the biological and chemical domain, so access comes with security, monitoring and enforcement terms
- OpenAI publishes no context window for it and compares it only with GPT-Rosalind-5.5; no independent benchmark score is recorded here yet
- Best for
- Drug discovery and life sciences research teams approved for OpenAI's trusted access
- Dual-use biology research that GPT-6 Astra is more likely to refuse
