Hey PH! Sarthak here 👋
Random stat that got me thinking — 4.5% of all ChatGPT usage is just translation. People are literally firing up a massive cloud model to translate a sentence. That felt like a huge waste to me, both in compute and in privacy.
So I built TweeTaal to take that offline. Smaller model, runs entirely on your iPhone, nothing ever leaves your device. Better for privacy, better for the planet, and honestly fast enough that you won't miss the cloud.
I also trained a custom Dutch ↔ English model from scratch — Dutch is surprisingly underserved despite being spoken by 25M+ people. Inference runs on MLX so it's properly optimized for Apple Silicon, not just a hacky port.
A few things I'm curious about:
Do you think about the compute cost of using LLMs for simple tasks?
Any other "boring" use cases you think deserve their own dedicated offline model?
What would make you actually ditch Google Translate?
Happy to get into the technical weeds if anyone's curious about the MLX side of things!
