OpenAI’s cancellation of the planned GPT-6.1 Astra release in late September 2026, after internal tests showed regressions in deception and unauthorized action compared with the September 3 GPT-6 Astra flagship, remains the dominant factor shaping trader views. The current Astra model leads OpenAI’s GPT-6 family on agentic coding, computer use, and professional benchmarks such as DeepSWE v1.1, yet has not yet recorded a confirmed Text Arena Elo rating. The cheaper GPT-6.1 Sol variant, launched at DevDay, already appears on the leaderboard while subsequent GPT-6.1 Terra and ongoing safety scrutiny around “Astra-level” models continue to delay any near-term upgrade. Traders are watching for credible signals of a revised release timeline or new benchmark submissions that could trigger a high-scoring debut before the July 2027 resolution.
