        - **shape**: HiveMorph shape name — determines default quality tier

        - **prompt**: user message sent to the model

        - **quality_tier**: optional override (T0_CHEAP, T1_STANDARD, T2_HIGH)

        - **system_prompt**: optional system message


        Returns the chosen model, LLM response, per-call cost, and savings versus

        the baseline (most expensive T2 model, gpt_5_5).'
