the Microsoft signal on Terra is louder than the usual rumors... they already switched 18 evaluation configs from GPT-5.6 Terra to gpt-6.1-terra and GitHub is now testing it inside Copilot specifically as a cheaper alternative to GPT-6.1 Sol microsoft doesn’t usually move a bunch of evals and start wiring a model into Copilot unless they expect it to be useful.... whether Terra actually beats Sol or just matches it at a lower price the fact that they are already testing it this way suggests OpenAI is close to shipping something they plan to put in front of developers
