Managing 1,000+ analytics models without governance is a liability, especially in energy markets.

ACES solved this by standardizing on Posit Team + Positron, bringing speed, structure, and trust back into their workflows.

How do you use AI assistants in data science without compromising sensitive data?

As tools like Positron Assistant and Databot gain the ability to execute code and access files, this question becomes more urgent.

Privacy and AI Assistants - Posit
Many of our LLM tools can execute code and access your files. What does this mean for privacy?

Thinking about running local models with coding agents like Positron Assistant? 💻

A new evaluation by @simonpcouch.com and @sara-altman.bsky.social suggests we aren't there yet. Between hardware hurdles and performance gaps, hosted models are still the best bet for now.

While coding agents like Positron Assistant and side::kick() are technically compatible with LLMs small enough to run on your laptop, the results leave much to be desired.
