Key Info

An OpenAI team member says GPT-6 Astra at low reasoning effort outperforms GPT-5.6 Sol at high effort, and recommends users switch to low or medium settings for Astra.

Highlights

• Astra on low already beats Sol on high, so high reasoning effort may be unnecessary.
• Users who were happy with Sol on high can likely drop to low or medium with Astra.
• Lower reasoning effort could mean faster responses and better efficiency without sacrificing quality.
