Tool calling and computer-use functions on Terra and Sol are restricted exclusively to the new Responses API; the migration frequently breaks production workflows, drops cache hit rates, and increases first-token latency — combined with ‘Sign in with ChatGPT’ and always-on Dots agents, developers read it as a lock-in play.
