Malde: Continual learning will be AI's next major unlock

Malde: Western open-source AI lags Chinese models at trillion-parameter scale
“I think America or the Western world has some work to do still. Like obviously having one trillion parameter models like Kimi or like an amazing models like GLM and DeepSeq, I don't think we're quite there yet for that size of model.”
Malde: Direct user modifications, not binary feedback, drive effective AI continual learning
“I think when people think about, like, online learning, continual learning, they'll first think of, like, accept, reject, or thumbs up, thumbs down, like some of those, like, kind of binary signals. It turns out that that's actually, like, very noisy. You can …”
