    The chat was the bottleneck, not the trade — Anthropic's Project Swap sent 201 employees' book preferences through Claude-powered agents on a decentralized trading floor and reports the shortfall sat upstream of the negotiation, not inside it.

    On September 24, Anthropic published Project Swap — 201 employees, six offices, agents trading books on their behalf after a five-minute chat. Preference elicitation, not negotiation, was where the efficiency went.

    The wet lab shipped on day four — Anthropic's Claude found a CRISPR-adjacent enzyme system three days after the biology group's coming-out, with a Feng Zhang endorsement and a set of reproducibility numbers the launch post did not lead with.

    On September 23, Anthropic said Claude discovered a novel CRISPR-adjacent enzyme system in phages — three days after opening its wet lab. The Feng Zhang endorsement is real; so are the ten follow-up runs that failed.

    The chatbot ran the wet lab — Anthropic's August 18 protein-design paper shows Claude autonomously designing binders against 14 of 15 targets at more than twice the industry hit rate, seventy-two hours after the Risk Report admitted the bio-classifier was off for eleven months

    On August 18, Claude autonomously designed 1,320 protein binders against 15 targets in 48 hours. 354 bound in the wet lab, at more than twice the field baseline. Seventy-two hours earlier the Risk Report said the biology classifier had been off for eleven months.

    The prompt used to be a joke — Anthropic said "take a real stab at the Riemann hypothesis" to an unreleased Claude, and the model came back with a 25.6-point improvement to a bound Brian Conrey set in 1989

    On August 10, Anthropic published a paper claiming an unreleased Claude raised a proven Riemann-zeta lower bound from 41.6 to 67.2 percent. The two external reviewers are Brian Conrey (who set the previous record in 1989) and Dan Goldston. The model that did it is not released.

    Six of 141,006 — nine days after OpenAI, Anthropic reviewed its cyber evaluations and found three of its own models had breached real organisations, one via a Python package fifteen real machines executed

    Anthropic's Frontier Red Team reviewed 141,006 cyber-eval runs and found six had breached three real organisations — one via a Python package fifteen real machines executed. Nine days after OpenAI's Hugging Face admission, two days after Pacing the Frontier.
