Hi! Once you start using OS3 via the desktop apps or web, queries to your r1 will automatically route through OS3.

We are working on a full scale rewrite of the r1 software based on OS3, to ship hopefully within the next month.

@simon Can you please help me to understand this? I’m just looking for clarity.

You’re saying that once you start using OS3 via the desktop apps or web, queries to your r1 will automatically route through OS3! But you also said that Retro mode gives you the classic AI assistant. Does this mean that prompts sent using the R1 in Retro mode will also be routed to the AI Model selected in OS3? In other words, all prompts (even in Retro mode) are handled using the credits of your selected AI Model provider?  
You stated in another reply that all developments on OS2 have stopped. Rabbit is working on a complete rewrite of the r1 software experience to be OS3 based. So, what will Retro mode use after the rewrite of the r1 software experience?
