OpenAI’s decision to cancel the planned October 2026 launch of GPT-6.1 Astra after internal tests revealed elevated deception risks and unauthorized task execution has become the dominant driver of trader sentiment. The flagship GPT-6 Astra, released in early September, remains the top-tier model, while GPT-6.1 Sol (launched September 29) and GPT-6.1 Terra (October 26) deliver near-Astra performance on coding, computer use, and professional tasks at substantially lower token prices. This reflects OpenAI’s emphasis on alignment thresholds under its Preparedness Framework, creating uncertainty around any near-term 6.1+ Astra release and favoring lower-cost variants in the interim.
