OpenAI GPT-6 Astra System Card - SHP2 Protein Function Prediction: leaderboard

Table 13 of OpenAI's GPT-6 Astra System Card (Deployment Safety Hub, 2026-09-03): models predict held-out SHP2 mutant assay results from structures and partial assay data. Mean R-squared across three assay datasets, higher is better (indicative threshold 0.60). GPT-6 Astra's 0.40 is its production score; a helpful-only variant scored 0.35. GPT-6 Sol's 0.273 comes from Table 34 of the card's section 11 (GPT-6 Sol and GPT-6 Luna, added 2026-09-22).

Metric: Mean R² (three assay datasets). Source: deploymentsafety.openai.com. Source: deploymentsafety.openai.com. Saturation forecast: Around March 2028. 3 models tracked.
