Ask HN: Are there other language/framework-specific LLMs?

We've been using V0 (https://v0.dev/) for a while now, and relative to other LLMs it definitely seems to be a level up in terms of the quality and readability of the code.

I've watched a few talks by the Vercel engineers and they mention that they've done a lot of work specifically for this by leaning into a strategy of:

* Training the model for specific language + frameworks (typescript, nextjs, react and shadcdn)

* Collecting and using high-quality code samples for training

I'm wondering if anyone else knows of any other model providers that have similar offerings where they're building LLMs to be better within the context of a specific language and/or framework (eg: Python + FastAPI, etc.).
