OpenAI's GPT-6 Astra achieves 99.9% on ARC-AGI-3, solves financial modeling tasks four times faster than human champions, and scores 100% on ExploitBench, outperforming Claude Opus 5 and GPT-5.6 Sol across coding, reverse engineering, and scientific workflow benchmarks.
OpenAI's GPT-6 Astra integrates reasoning, computer operation, and continuous execution into a single model, scoring 72.6% on OSWorld 2.0, 57.9% on Terminal-Bench 4.0, and 99.9% on ARC-AGI-3 with a Provider Adapter, while demonstrating autonomous tax filing, CRM updates, code migration, and zero-day vulnerability discovery — all with new cross-context memory and safety boundaries.
OpenAI’s upcoming GPT‑6 model, codenamed Astra, has been given a new "Critical" security rating after ExploitBench and internal tests showed it can discover unknown vulnerabilities, craft full zero‑day attack chains, and operate autonomously in hardened environments, prompting both excitement and genuine anxiety within the company.
OpenAI unveiled three GPT‑5.6 models—Sol, Terra and Luna—featuring tiered pricing, record‑breaking benchmark scores in programming, security and biology, new max and ultra inference modes, and a limited early rollout, while also noting several unexpected failure cases.
