Ethical LLMs

See: What is an Ethical LLM?, my first attempt at this, which also has some additional context

What Makes For an Ethical LLM?

This is by no means an exhaustive list, so if you think I missed anything important, have a good example you think bears inclusion, or know of an “ethical LLM” project you think should have been included, let me know on Mastodon!

Dimensions of an Ethical LLM

So… Are There Any?

I don’t know, but here are a few potential options. I haven’t done a deep dive on any of them yet, I mostly know that they are pitching themselves as ethical alternatives.

Thaura

Thaura is a very interesting one. An actual product, not a standalone model. Built around a non US-produced model (GLM-4.5 Air, at the time of this writing). Started by a couple of brothers from Syria who were sick of using tech that contributed to e.g. the genocide in Palestine. They seem to be claiming they’ve fixed the issues around sycophancy, which I find exciting and intriguing. They also lay out explicitly what “ethical” means to them in a set of core principles that seem more grounded in reality than any similar statements I’ve seen coming out of OpenAI or Anthropic. Shout out to my brother for tipping me off to this one!

Apertus

Apertus, an LLM being offered by the Swiss government under the Apache license. Seems to be based off of Common Crawl? I think the branding looks a bit fascy, but I’m open to the idea that they’re not the only ones who get to use V’s instead of U’s. They too have a document outlining their principles which by my skimming are decidedly non-fascist, so let’s just call the branding different tastes, maybe.

Vintage Vegan

These models aren’t trying to solve the same kinds of ethical issues as Thaura or Apertus. They’re focused primarily on the issue of training data licensing (AKA these are attempts at “vegan” models) and they’re also experimental research into what we can learn by making specific and time-bound language models, in this case Victorian-era text only. Hence the “vintage” models moniker. Both used modern “non-vegan” LLMs in their creation, so there is a bootstrap/contamination issue that hasn’t yet been resolved.
