The milestone, originally set for May 15, was delayed to focus on broader security efforts. Phase 1 only covers foundational components and cost analysis—not a deployable system—yet its delay underscores tensions between rapid AI development and safety engineering.\n\nThe company has avoided discussing the delay, despite its significance for its planned $2 trillion IPO. Meanwhile, Anthropic has prioritized product releases: Claude now powers 26% of its R&D, Claude Opus 5.5 cut workload costs by 40%, and a biology lab used 950 Claude agents to discover a CRISPR-like enzyme system in 21 hours.","keyPoints":["Anthropic’s September 30 deadline for Phase 1 of provable-inference prototype passed without confirmation","Phase 1 only includes component inventory and cost analysis, not a deployable system","Claude now drives 26% of Anthropic’s R&D, with Opus 5.5 cutting costs by 40%"],"whyItMatters":"The delay raises questions about Anthropic’s ability to balance rapid AI innovation with safety, critical for its IPO ambitions and trust in its security claims.","category":{"slug":"research","name":"Research","url":"https://digestai.news/category/research"},"entities":{"companies":["Anthropic"],"models":["Claude","Claude Opus 5.5"],"people":[]},"firstPublishedAt":"2026-09-28T03:37:00Z","updatedAt":"2026-09-28T03:37:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"finance.yahoo.com","title":"Anthropic’s Self-Imposed Safety Deadline Arrives in Two Days.
