Lessons after a Half-billion GPT Tokens
[custom_views_and_hn_comments hn_id=”40015185″] My startup Truss (gettruss.io) released a few LLM-heavy features in the last six months, and the narrative around LLMs that I read on Hacker News is now starting to diverge from my reality, so I thought I’d share some of the more “surprising” lessons after churning…

Building an email-to-calendar LLM
Talk is cheap, show me the code Introduction A common problem my friends and I have is receiving actionable emails whose priorities are medium level. They do require action of some sort ($ \geq lowest\ priority$), but the action is due in the near future ($\leq highest\ priority$). I tend to skim over these emails…

I'm going to keep opting out
Marketing, solicitations, advertising, political contact, direct mailers, email campaigns, cookies, ads — it's all opt out. It puts the burden on you to opt out of each communication each message, each outreach from a loyalty program. It can feel like weeding a garden, but that garden is your attention. The weeds keep…

Where is Noether's principle in machine learning?
Physics likes optimization! Subject to its boundary conditions, the time evolution of a physical system is a critical point for a quantity called an action. This point of view sets the stage for Noether's principle , a remarkable correspondence between continuous invariances of the action and conservation laws of the…
