ChatGPT quietly makes GPT-6.1 Sol the default, users report sharper voice chats

User shaunralston reports ChatGPT's default model is now "GPT-6.1 Sol" (a screenshot shows the picker with 6.1 Sol, 6 Astra, 6 Sol, 6 Luna, and 5.6-series options), and that combined with recent memory upgrades, voice chats feel sharper in humor and emotional nuance with better retention of older memories — best experienced with Standard Voice on iPhone or Android. Third-party impression, not an official announcement; broader testing pending.
