I've noticed that GPT-6 Sol in ChatGPT may have improved speed and task performance, but seems to have lost some conversational finesse compared to GPT-5.6 Sol.
Regressions I've noticed :
1. Reuses similar dialogue, phrases, and ideas too frequently.
2. Struggles to consistently follow established preferences without repeated reminders.
3. Starts conversations with personality and energy, but gradually becomes generic, repetitive, and less engaging in longer chats, especially with default settings
Quality is reduced.
