Most large orgs do not need to train end users. They just need to add glm-5.2 to their router and their in house harness will pick it up. Then slowly limit usage on anthropic models and people will swap willingly. It's a simple /model command in every harness.
Yeah, most big orgs are pushing the idea of 'whitelabel' LLMs. Even if they choose to hang on to Claude Opus, they won't name it, they'll just call it the 'extra mode' and 'auto mode' will eventually switch to a local LLM in their harness.
