Because it is. From OpenAI 9.2.1 CoT Controllability We find that GPT-6 Astra’s CoT controllability is substantially higher than that of GPT-5.6 Sol and GPT-5.5 Thinking (Figure 28)....For example, among CoTs between 750 and 1,250 tokens long, GPT-6 Astra successfully controls 60.9%, compared with 16.1% for GPT-5.6 Sol and 1.7% for GPT-5.5 Thinking. This increase in controllability is consistent across the three datasets (Figure 29) and across the eight CoT instruction types (Figure 30). Qualitatively, GPT-6 Astra is now capable of generating very long CoTs satisfying complex constraints, e.g., alternating between lowercase and uppercase letters (Table 9) and pretending to reason about a different question (Table 10).[1] 9.3 External Evaluation for Monitorability - UK AISI To assess monitorability, UK AISI evaluated Astra using four non-agentic evaluations: No-CoT math time horizon: Astra can solve significantly more difficult math problems in a single forward pass than past models. UK AISI measured Astra’s time horizon at 30.9 minutes compared to 3.6 minutes for GPT 5.6 Sol (Figure 1).
