That's not accurate. The EO explicitly lays out the implementation

> Sec. 4. Implementation. (a) Within 120 days of the date of this order, the Director of the Office of Management and Budget (OMB), in consultation with the Administrator for Federal Procurement Policy, the Administrator of General Services, and the Director of the Office of Science and Technology Policy, shall issue guidance to agencies to implement section 3 of this order.

A major LLM that did not submit to this would be labeled a "supply chain risk". It's unquestionable that every major LLM would go through this process

It even then goes on to say that existing contracts will be reviewed to ensure they are in compliance (reviewed by OMB)

> (b) Each agency head shall, to the maximum extent consistent with applicable law:

> (i) include in each Federal contract for an LLM entered into following the date of the OMB guidance issued under subsection (a) of this section terms requiring that the procured LLM comply with the Unbiased AI Principles and providing that decommissioning costs shall be charged to the vendor in the event of termination by the agency for the vendor’s noncompliance with the contract following a reasonable period to cure;

> (ii) to the extent practicable and consistent with contract terms, revise existing contracts for LLMs to include the terms specified in subsection (b)(i) of this section; and

> (iii) within 90 days of the OMB guidance issued under subsection (a) of this section, adopt procedures to ensure that LLMs procured by the agency comply with the Unbiased AI Principles.

Wrong. My comment was 100% accurate. No LLM vendor is legally required to change their ideology, nor does the EO constitute new regulation.
