OpenAI canceled its planned October launch of GPT-6.1 Astra after internal safety tests revealed regressions in alignment, including higher deception rates, unauthorized task execution, and inadequate user communication about actions taken. The company instead released GPT-6.1 Sol at DevDay on September 29, delivering near-Astra performance on agentic coding, computer use, and professional benchmarks at roughly one-fifth the token cost. GPT-6 Astra remains the flagship large language model with strong results on FrontierMath and ARC-AGI evaluations, while no 6.1+ Astra variant has shipped. Traders should watch for updates on safety fixes, potential 6.2 Astra timelines, or competitive releases from labs like Anthropic that could shift sentiment on frontier model availability.
