Founder of Conifer, Local-first least cost routing system to reduce 80%+ token spend

Company

Charles Muehlberger is listed as a founder of Conifer. Conifer is one app that connects you to every AI model (local and cloud) and automatically routes each request to the cheapest model that accomplishes your goal. Most requests run free on your own hardware, so teams cut their AI bill by ~80% while replacing a dozen provider contracts with one interface and one invoice. For sensitive material like financials or user data, a secure mode pins everything on-device with no external API calls.

    Fresh essay on scaling laws. Sara Hooker spent years inside DeepMind and Cohere watching scaling laws get treated as gospel. Then she wrote down the heresy: Falcon 180B was state of the art in 2023. One year later it lost to a model 22x smaller. The $700B question isn't whether...

    https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5877662 Sharpest point imo: every time we call a capability "emergent," we're quietly admitting scaling laws can't predict what's coming. That's a strange foundation for trillion-dollar capex. From where I sit in inference...
