Anthropic's blind design using unpublished targets addresses the recall problem that weakens many chemistry demonstrations.\n\nAnthropic said on November 9th that three Claude models each produced a complete synthetic route to four targets from unpublished syntheses after receiving one image of each target, with no internet, literature or reaction-database access and local code as the only tool.
