My subscription expires tomorrow. Had subscribed ~March, eventually ended up paying for the $200 tier. However, there isn't enough of a moat for me to keep spending $200 if the models aren't being helpful anymore.
The unnecessarily jargon filled language was already pretty bad, but the latest Opus/Fable also just didn't seem to go far enough when asked to look into something, often leading me in circles.
Yeah it feels like they tune or 'optimize' the models after release and they get less useful to me as time goes by. I'm most productive the first few days after a release. Noticed this since opus 4.6.
