The DeepMind Blog announcement is a notable step toward more credible model evaluation, but its real-world impact remains to be seen. While the cryptographic 'box' addresses a genuine technical problem, the pilot involves a single, less-capable 'Lite' model and a small consortium of partners. For this to become a meaningful industry standard, Google would need to apply the method to its most advanced models and open the protocol for broader, truly independent adoption. In our view, the pilot's success will hinge less on the technology and more on whether Google and other frontier labs commit to its use at scale.
