I'm sad man. GPT-6-Sol has no soul, no humour, just a mechanical robot compared to GPT-5.6-Sol. I'm going to really miss 5.6-Sol when they retire it. I can now sympathize with the "Bring Back 4o" crowd.
The thing is, I saw this coming. This is why I trained and released Synthia, to have that humour, the warmth and the empathy.
Give this a go in your personal AIs, I'm always open to feedback and will keep improving.
I'm bringing back Synthia.
Here's Synthia-4-27B:
Synthia-4-27B is fine-tuned as a personal AI with the ability to do real work. It combines an expressive, conversational presence, with the tool use and persistence needed for coding, research, planning, creative work, and day-to-day assistance.
It's built on Qwen/Qwen3.8-27B, and post-trained on a deliberate blend: 64K-token long-context agentic traces, a combination of day-to-day tasks (such as web browsing, news), research (read and summarize articles), creative work (writing blogs) and engineering (pretty heavy and novel work).
Enjoy!
