Anthropic releases Claude Opus 5 — lower-cost model claiming near‑frontier performance

Anthropic announced Claude Opus 5, a new model positioned as a cost‑efficient successor to Opus 4.8 and the new default on Claude Max (and the strongest on Claude Pro). Anthropic says Opus 5 matches or exceeds prior models on many coding, knowledge‑work and scientific benchmarks (Frontier‑Bench, GDPval‑AA, CursorBench, ARC‑AGI, Zapier AutomationBench, OSWorld) at lower cost per task while remaining behind Mythos 5 on security and biology frontier tasks; the company also reports improved alignment and safety in pre‑deployment audits and links a System Card for more details.

Anthropic says it does not advocate banning open-weights models and urges chip controls, distillation crackdowns, and mandatory safety testing

Anthropic clarifies it has never supported a ban on open-weights models, calling non-dangerous open models a public good. The company says bans would not address its main national-security concerns (authoritarian states gaining superior AI and misuse for cyber/biological attacks) and instead advocates restricting sales of powerful chips to China, cracking down on industrial-scale distillation, and requiring mandatory safety testing of sufficiently capable models.
