Anthropic introduced Claude Opus 5.5, claiming performance comparable to Claude Fable 5.1 on most work at 40% lower operating cost than Opus 5. External evaluations also produced Anthropic's strongest automated behavioral-audit result to date.
Claude Code cloud sessions are now generally available, allowing long-running coding tasks to continue on remote servers after a laptop is closed. Sessions run on separate branches through linked GitHub accounts and can be started from the web, mobile, desktop, or CLI.
Anthropic confirmed that it runs a Bay Area wet lab in which Claude directs physical biology experiments. The facility was built on the company’s $400 million acquisition of Coefficient Bio.
Anthropic's Claude used 950 agents over 21 hours and 210 million tokens to search DNA databases, identifying ART, a previously unknown array-associated reverse transcriptase system that may cut, copy, and paste DNA. Scientists directed the work and conducted the laboratory experiments.
