You can also download the same model and run it locally without data leaving your machine, the Zed tram released it as open weights: https://huggingface.co/zed-industries/zeta-2
That's all great (genuine), however my concern is less around "I can do X", more around "I can guarantee it cannot do Y" – ideally in one, global, obvious place.
At the moment it seems it's great for personal development and development in environments where concerns around IP are less of an issue.
It's not so clear how to use it in corporation context where you'd be in breach of employment contract accidentally because defaults mean sending confidential IP to 3rd parties.
Yes, Zed was first harness where you could seriously use local models. The issue is more about not having to check so many options to make sure it's all local. You can set up local model for chat but your auto completions will still be sending your code remotely.
