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.

Characterizing web search behavior of conversational LLM agents across four platforms

arXiv:2609.19244v1 reports the first study of agentic Web search across four conversational platforms (ChatGPT, Claude, Grok, DeepSeek), combining real-world user interactions (in vivo) with controlled API experiments (in vitro). The paper analyzes when agents choose to invoke Web search, their query strategies, domain preferences in returned results, and how they transform results into grounded responses, finding substantial variability across platforms, platform-specific result biases, and some reliance on uncited search results.
