[Feature Request] Support OAuth subscription with non-Anthropic model providers

Bug Description
please let me use my oauth subscription with hermes, i will be forced out of claude, and claude is my first Ai automations framework i built but now am moving away because i need model agnostic setups where i'm not dependent on just one company. please understand that this is what a customer wants, your inference, with my memory files and reference files and specs that are transferrable accross model providers
