A reviewer describes hands-on use of Duet, an Anthropic-linked personal-assistant chat tool reportedly built on the Opus 5.5 model, after testing several competing assistant apps like Muse, Dot and NanoClaw. The reviewer highlights three features: faster response times than other Claude interfaces, automatic creation and management of conversation 'channels' to organize work, and per-channel access restrictions to GitHub repositories that avoid requesting user credentials.

Anthropic has released Claude Duet, a new app built on Opus 5.5 that connects to work tools like Gmail, calendar and Slack to proactively manage tasks for professionals. The app flags priorities, surfaces what needs attention, and indicates what can wait, while including safeguards that block or confirm before sharing sensitive data. Duet is currently in research preview, limited to Pro and Max subscribers, with a waitlist open for others.

Google has launched Gemini 4 Argon, a frontier AI model built for deep reasoning in finance, coding, creative writing and cybersecurity tasks. Independent benchmarking firm Artificial Analysis found Argon matches OpenAI's GPT-6 Astra on its Intelligence Index at roughly 60 percent of the cost, with a notably lower hallucination rate of 15 percent. Google says it is already using Argon internally for quantum computing research, codebase migrations, and data center memory optimization, where it freed up 300 TiB of memory.

Developer Carter Leffen used OpenAI's Astra model to locate and decrypt an Enigma-encoded message that had remained unsolved since 2005, with the model conducting its own archival research and building a simulator of the Enigma machine. Cryptology researcher Frode Weirerud, who maintains a database of unbroken Enigma messages, independently verified the solution and called it 'awe' inspiring. Anthropic's Opus model reportedly cracked a separate long-unsolved message as well.

Anthropic released Opus 5.5, claiming it beats its larger Fable model on many coding and knowledge benchmarks while costing 20% less per output token and running faster. The model also communicates more plainly, avoiding jargon and leading with key information. Sonnet 5.5 and Haiku 5.5 are expected to follow in coming weeks with similar gains.
