Definitely not using something like an Anthropic model for research, FWIW. The amount of data the LLM needs to consume to build context for even simple trade sequence comprehension makes it next to useless.

There are a litany of other mathematical and ML models that can more aptly be applied to the space.

But to answer your question more directly, yeah...there's no way in hell you'd let the questions your traders are asking in research out of the four walls of your building if you can avoid it.
