Week 33 of 2026 put three frontier models on the table inside 48 hours — DeepSeek V4 Pro at 1.6T params under MIT, Grok 4.6 one point behind Claude Opus 5, Meta back in open weights with Muse-Glimmer-30B. Then a paper showed the encrypted reasoning those closed models hide can be decoded by a weaker sibling model, and 315,320 scraped blocks gave up 182 credentials.
