  1. 2026-08-11 / HACKER NEWSProbing Study Says Opus 5's Real Knowledge Ends Around January 2026 Despite a Claimed May 2026 CutoffPublished August 10, 2026, sshh's analysis probed Anthropic's Opus 4.7 and 5 and Sonnet variants alongside OpenAI's GPT-5.x line using three methods: 8-way multiple choice on daily Wikipedia facts to find where accuracy degrades, direct self-reported date queries, and 50 "what model are you?" probes. Inferred cutoffs land at late December 2025 for Opus 4.7+ and late February 2026 for GPT-5.6, with Opus 5's usable knowledge appearing to stop around January 2026 versus its claimed May 2026 cutoff. The author also reports clear signatures of labs training on prior-model outputs and user conversations — Sonnet 5 regularly self-identifies as GPT-4. 145 points, 23 comments.
