Been using GPT-6.1 Sol for a few hours now.
No hype, just my experience so far: I’m not impressed.
It’s slow, burns through ChatGPT usage, doesn’t consistently follow instructions, and the efficiency just isn’t there.
Even if it’s cheaper to run, I’d still take Opus 5.5 or Sonnet 5.5 over it right now.
Maybe my opinion changes with more testing, but first impressions? Pretty disappointing.
