Better together.
Models from different providers work as one team. A GPT director sets the goal, a Claude manager splits it, a Claude senior and a Kimi junior build it, and they review, question and correct each other in the same conversation you are reading. No glue code, no copy-pasting between tools.
Spend where the thinking matters. Give each role the model that fits its job and budget: a capable model for scoping and review, lower-cost models for bounded work. Swap a model on one role and the rest of the team keeps working. The model name sits beside every message, so you always know who said what, with what.
