Grammarly can cut down their costs if they use those models themselves. The current LLM advancements aren't disruptive but incremental. What's the hurdle you see they can't rely on their existing distribution and expand from there?
Why would using a more-expensive technology cut their costs?
It's the dot-com strategy. They'll lose money on every sale but make it up in volume.
That’s true but I can replace Grammarly in a few hours with Claude. 99% of the functionality. Then, I can spend a couple more days to add stuff that they can’t add due to copyright.
Grammarly has a function that replaces phrases that are typical for LLM output. Good luck coding that in a few hours.
Last I read, they run it off of MSFT/OpenAI.
I'm sure they haven't created their own model. Probably fine-tuned it + constantly updating a database of the most occurring phrases from all LLMs.
