What this changes for UK buyers
Teams can test the new route without a higher headline token tier, but product-surface access, tools, agent persistence, review and complete cost still need migration evidence.
What buyers should do
Replay frozen GPT-6 Sol tasks with identical tools, permissions and acceptance criteria; measure accepted work, persistence after correction, review and complete billed cost.
