A thread sharing six takeaways from a conversation with Nous Research co-founder Karan about getting more from Hermes Agent.

Key ideas

The “personal” part of a personal agent is mostly its memory of your conversations and the skills you build on top of it, not the base model itself.
Karan recommends trying different personas with /personality, such as teacher, concise, kawaii, or pirate.
He also suggests separating agents that do the work from agents that evaluate it, to avoid reward hacking and make outputs more reliable.

The post argues that model swapping matters less once the agent has strong context and a useful skill set around it.
