Anthropic launched Claude Opus 5 — its new default Opus, priced at $5/$25 per million (unchanged from Opus 4.8 and half of Fable 5's rate) with a per-request low/medium/high effort dial that trades cost for capability, and Anthropic's numbers put it around Fable 5-level intelligence with a new state-of-the-art on agentic coding, reframing the flagship tier as a cheaper, tunable model rather than a pricier one.

A wave of independent benchmarks this week put Zhipu's freely downloadable, MIT-licensed GLM-5.2 at or near restricted US frontier models on cybersecurity work — the exact capability the June 12 Fable 5 / Mythos 5 export ban was meant to contain — with CNBC clocking it within a point of Opus 4.8 on agentic tasks at roughly a fifth of the cost, the first concrete sign that API-level export controls can't hold a capability once an open-weight model reaches it.
