I still won't use what? I use Opus now, and I will use Opus then too, but as I clearly stated:

My default model has now dropped to Sonnet, because Sonnet can now do most of my tasks, and we already use Kimi, Deepseek, and Qwen.

They're just not cost-effective enough to be my main driver yet. They are however cheap enough that for things where the Claude TOS does not let me use my subscription, they still add substantial value. Just not nearly as much as I'd like.

The bulk of my tasks won't get harder as time passes, and so will move down the value chain as the cheaper models get better.

For the small proportion of my tasks that benefits from a smarter model, I will use the smartest model I can afford.
