Frozen v2's effectiveness is constrained by architectural lock-in risk, as the chip would become less useful if Google makes major changes to Gemini's design

"The chip would work well only if future Gemini models continue using the same core architecture. If Google makes major changes to Gemini's design in the future, Frozen v2 may become less useful."

"The trade-off is flexibility. The chip would work with future Gemini models only if Google sticks with the same underlying architecture. Google reportedly currently views Frozen v2 partly as a trial run and does not plan to produce it at the same scale as its TPUs."
