This model is open source and Beats all proprietary models in benchmarks. How is this stagnant?
The only non-thinking LLM the new V3 doesn't decisively thrash is GPT 4.5 which is more than 100 times more expensive than V3 and yet is only a few (essentially negligible) percentage points better than it.
It's pretty good, especially nice since it's open source, but it's not going to be a daily driver for most people.
