AI News Digest | OpenAI Codex Evolves into System-Level Operator; Claude Opus 4.7 Explodes; Ternary 1.58-bit Model Released

1. Core Model Releases & Technical Iterations

• Claude Opus 4.7 Officially Launches with Performance Controversy Anthropic has released the new generation Opus 4.7, which performs excellently on Vending-Bench 2. The official subscription limits have been raised to compensate for the consumption of its “long thinking.” However, experts like Ethan Mollick point out that its “adaptive thinking” has flaws that cannot be manually intervened, often misjudging non-technical tasks as “low intelligence” requirements.
