Is this better than Positron Assistant? https://positron.posit.co/assistant.html
Practically, Positron also requires you to use your own LLM keys (so you're on the hook for the tokens/long context, and if you don't have a BAA or ZDR, you may not be able to use it with sensitive data). For Rao, we manage the tokens and are moving quickly towards HIPAA/SOC 2.
We also plan to develop something similar to Positron in the future.
Also note that Positron perma-unlocks the internal APIs that Microsoft Copilot Chat uses, so any extension can use them. "Positron Assistant" is itself mostly implemented as an extension. So it's possible for a 3rd party extension to become a chat participant in Positron or integrate with the Chat panel/inline chat/etc.
