If you have an use case where you need speed and not the smartest models, GPT-OSS-120B on Cerebras is surprisingly cheap[1] and outputs 3,000 tokens per second. I just started using this for summaries in my RSS reader and the ~1 second UI responsiveness is really nice.
No, Guardian Angels. But to fix pretraining/dynamic evaluation, you need to enrich the principal's data a lot, I think, and dumping in fulltext of references is a good way to ensure the LLM personas have access to the principal's context and avoid encouraging confabulation. (Gwern.net essays/annotations/Wikipedia serve as a kind of implicit 'reference wiki', as do the analyses/writeups we are having the LLMs generate to reverse-engineer writing.)
Most of Cerebras' models are enterprise-only, and I don't even want to think about what a dedicated Sol endpoint would cost. I would be very excited if they added this to the pay-per-request API though.

Yeah, now I'm considering making an AI read every relevant arXiv paper and LessWrong post for a topic and write a citation-heavy reference wiki. Doing this for all of arXiv would still be expensive, but doing it for every paper that vaguely references a topic like Parameter Decomposition or SAEs seems surprisingly tractable.
