It is not a full summary and says nothing about implementation. A “not found” record states which part of the edition was inspected. It is not a claim that the text was deleted.
Threshold or trigger CBRN weapons Capability Threshold “The ability to significantly help individuals or groups with basic technical backgrounds (e.g., undergraduate STEM degrees) create/obtain and deploy CBRN weapons.” PDF p. 7 (printed p. 3), §2 Capability Thresholds and Required Safeguards, table row 'Chemical, Biological, Radiological, and Nuclear (CBRN) weapons', Capability Thresholds column Inspect claim & evidence ↗ Required action Commitment not to train or deploy without adequate safeguards “In September 2023, we released our Responsible Scaling Policy (RSP), a public commitment not to train or deploy models capable of causing catastrophic harm unless we have implemented safety and security measures that will keep risks below acceptable levels.” PDF p. 2 (unnumbered), Executive Summary, first paragraph, first sentence Inspect claim & evidence ↗ Required action Pause training until ASL-3 Security Standard implemented “If the pretraining model’s capabilities are comparable or greater, we will pause training until we have implemented the ASL-3 Security Standard and established it is sufficient for the model.” PDF p. 15 (printed p. 11), §6.2 Restrict Deployment and Further Scaling, bullet 'Monitoring pretraining', third sentence Inspect claim & evidence ↗ Required action Restrict deployment and scaling if safeguards showing fails “If, however, we are unable to make the showing required above, we will restrict model deployment and further scaling.” PDF p. 14 (printed p. 10), §4.3 Safeguards Decision, final sentence (after the bulleted process) Inspect claim & evidence ↗ Who decides CEO and RSO deployment decision shared with Board and LTBT “If the CEO and RSO decide to proceed with deployment and training, they will share their decision–as well as the underlying Capability Report, internal feedback, and any external feedback–with the Board of Directors and the Long-Term Benefit Trust before moving forward.” Decides: CEO · Decides: Responsible Scaling Officer · Informed: Board of Directors · Informed: Long-Term Benefit Trust PDF p. 13 (printed p. 9), §4.3 Safeguards Decision, fourth bullet Inspect claim & evidence ↗ Who decides Policy changes proposed by CEO and RSO, approved by Board “Changes to this policy will be proposed by the CEO and the Responsible Scaling Officer and approved by the Board of Directors, in consultation with the Long-Term Benefit Trust.” Recommends: CEO · Recommends: Responsible Scaling Officer · Decides: Board of Directors · Consulted: Long-Term Benefit Trust PDF p. 16 (printed p. 12), §7.1 Internal Governance, numbered item 7 ('Policy changes'), first sentence Inspect claim & evidence ↗ Exception Required Safeguards may be lowered if another actor passes a threshold “In such a scenario, because the incremental increase in risk attributable to us would be small, we might decide to lower the Required Safeguards.” PDF p. 16, footnote 18, second sentence Inspect claim & evidence ↗ Exception May deploy and train above threshold once ASL-3 Required Safeguards met “If, after the evaluations above, we determine that we have met the ASL-3 Required Safeguards, then we may proceed with deploying and training models above the Capability Threshold, provided we have also conducted a follow-up capability assessment.” PDF p. 13 (printed p. 9), §4.3 Safeguards Decision, first paragraph, first sentence Inspect claim & evidence ↗ Exception ASL-3 Security Standard alone suffices to continue training “We consider implementation of the ASL-3 Security Standard alone sufficient to continue training, regardless of whether the ASL-3 Deployment Standard is satisfied.” PDF p. 15 (printed p. 11), footnote 14 (attached to the §6.2 'Monitoring pretraining' bullet), first sentence Inspect claim & evidence ↗ Not found in the inspected text CISO and CEO convened to decide on weight deletion Inspected: RSP v2.0 (effective October 15, 2024), whole text layer, PDF pp. 1–22: cover, summary and contents (pp. 1–4); Introduction and §§1–7 (pp. 5–17); Appendices A–C (pp. 18–20); Changelog (pp. 21–22).
